A Bibliography of Pelagic Tunicates Naturalis
Waard-Pouw, G. van; Soest, R.W.M. van.
The present bibliography on pelagic Tunicates has been compiled over a period of 4 years, mainly by the first author. It is meant, not as an official publication, but as a working aid for students of pelagic Tunicates. It comprises about 1300-1400 different titles of books and articles. For obvious reasons the mere listing of all those titles in alphabetical order would be impractical for specialized demands. Splitting this list in as many subheadings as possible in a way like the Zoological Record would be ideal. However, many articles and books are difficult to place under one heading; the same titles would have to be mentioned under a number of different headings. With as many headings as possible this would mean a multiplication of the 1300-1400 titles...

Haliclona (Halichoclona) vanderlandi spec. nov. (Porifera: Demospongiae: Haplosclerida) from Indonesia Naturalis
Weerdt, W.H. de; Soest, R.W.M. van.
A new sponge species, Haliclona (Halichoclona) vanderlandi is described from three Indonesian localities: Take Bone Rata, Kapoposang (SW Sulawesi) and Manadotua Island (NE Sulawesi). The species belongs to the family Chalinidae and is assigned to the subgenus Halichoclona of the genus Haliclona, hitherto known as the “fistulosa” group as distinguished by de Weerdt (1989).

A revision of the megacanthoxea-bearing tetillids (Porifera, Spirophorida), with a description of a new species Naturalis
Soest, R.W.M. van.
A sponge collection dredged by Dr. P. WAGENAAR HUMMELINCK in the vicinity of Barbados (West Indies) contained a Cinachyralike specimen bearing large and conspicuous acanthoxea. This find induced the present author to re-examine all specimens with similar spiculation reported so far. A review of the literature revealed that a total of three such specimens has been described in two different genera, all as separate species, viz. Acanthotetilla hemisphaerica Burton, 1959, Acanthocinachyra enigmatica Levi, 1964, and Acanthocinachyra seychellensis Thomas, 1973. Both genera are reported to differ in the presence (genus Acanthocinachyra) or absence (genus Acanthotetilla) of sigmaspire microscleres. In view of the close similarity of the two genera it seemed wise...

Phylogenetic classification of the halichondrids (Porifera, Demospongiae) Naturalis
Soest, R.W.M. van; Díaz, Maria Cristina; Pomponi, Shirley A..
Using a multicharacter approach and numerical cladistic computer programs a phylogenetic analysis is made of a newly defined order Halichondrida (which includes all Halichondrida and parts of the Axinellida sensu Lévi, 1973), with emphasis on the newly defined family Halichondriidae (which includes the families Halichondriidae and Hymeniacidonidae sensu Lévi, 1973, and some genera formerly assigned to the Axinellidae and Desmoxyidae). The newly defined order consists of the “old” families Axinellidae/Bubaridae and Desmoxyidae, a “new” family Dictyonellidae (containing Dictyonella, Acanthella, Liosina and Dactylella), and the new concept of the family Halichondriidae. On the basis of numerous specimens, including many type and other original material from...

Taxonomy of the subfamily Cyclosalpinae Yount, 1954 (Tunicata, Thaliacea), with descriptions of two new species Naturalis
Soest, R.W.M. van.
The genera Cyclosalpa de Blainville, 1827 and Helicosalpa Todaro, 1902 are revised on the basis of material from all three oceans. Two new species, Cyclosalpa foxtoni and Cyclosalpa ihlei are described, and four taxa, formerly described as varieties or subspecies, are raised to specific rank. The existence of morphological groups of species within the genus Cyclosalpa is discussed.

Indonesian sponges of the genus Petrosia Vosmaer (Demospongiae: Haplosclerida) Naturalis
Voogd, N.J. de; Soest, R.W.M. van.
Sponges of the genus Petrosia (Demospongiae: Haplosclerida) are large and characteristic components of many Indonesian reefs. We identify and provide descriptions of seven species of Petrosia collected recently on SW Sulawesi reefs (Eastern Indonesia), two of which are new to science: Petrosia (Petrosia) alfiani spec. nov. and Petrosia (Petrosia) hoeksemai spec. nov. Additional species recorded are Petrosia (Petrosia) lignosa Wilson, 1925, Petrosia (Petrosia) nigricans Lindgren, 1897, Petrosia (Petrosia) plana Wilson, 1925, Petrosia (Strongylophora) corticata (Wilson, 1925) and Petrosia (Strongylophora) strongylata Thiele, 1903. The species are discussed and compared with Petrosia records from other Indonesian and neighbouring Indo-West Pacific areas. We...

Amsterdam Expeditions to the West Indian Islands, Report 13. Marine sponges from an island cave on San Salvador Island, Bahamas Naturalis
Soest, R.W.M. van; Sass, Daniel B..
Dixon Hill Lighthouse Cave, about 800 m (0.5 miles) inshore on San Salvador Island, Bahamas, was found to hold populations of three sponge species new to science, viz. Pellina penicilliformis n. sp., Prosuberites geracei n. sp., and Cinachyra subterranea n. sp. The new species are described and figured, and compared with Caribbean congeneric species. The geological history of the cave is described and its implication for ideas on speciation rates in sponges is discussed.

A new species of Biemna (Porifera, Poecilosclerida) from the Sultanate of Oman Naturalis
Soest, R.W.M. van; Beglinger, E.J..
Recent (1998) collecting off the coasts of Oman in the course of the EC-MAS3 funded ‘Symbiosponge’ project yielded three species of the genus Biemna Gray, 1867 (Demospongiae, Poecilosclerida, Mycalina, Desmacellidae) not previously known from the area. One of these appeared to be new to science and is described as Biemna omanensis n.sp.. Its distinguishing features comprise the possession of oxea megascleres, which is of rare occurrence in Biemna, and a full complement of microscleres including microxeas, sigmas, commata, all of which are divisible in two non-overlapping size categories, and raphides. One of the other two species conformed to an earlier described species Biemna ciocalyptoides Burton, 1959, which was discovered to be a junior synonym of...

Affinities of the family Sollasellidae (Porifera, Demospongiae). II. Molecular evidence Naturalis
Erpenbeck, D.; Hooper, J.N.A.; List-Armitage, S.E.; Degnan, B.M.; Wörheide, G.; Soest, R.W.M. van.
This is the second part of a revision and re-classification of the demosponge family Sollasellidae, and an example of a successful use of combined morphological and molecular data. Sollasella had been a poorly known, long forgotten taxon, placed incertae sedis in the order Hadromerida in the last major revision of the demosponges. It has recently been suggested to belong to Raspailiidae in the order Poecilosclerida due to striking morphological similarities. The present analysis verified this re-classification using molecular markers. Comparing 28S rDNA fragments of Sollasella cervicornis, a newly described species S. moretonensis and a representative set of raspailiid and hadromerid samples. In our analyses Sollasella clearly clusters inside the...

A new Agelas (Demospongiae: Agelasida: Agelasidae) from the Thousands Islands, West-Java, Indonesia Naturalis
Voogd, N.J. de; Parra-Velandia, F.J.; Soest, R.W.M. van.
Agelas linnaei spec.nov. (Porifera: Demospongiae: Agelasida: Agelasidae) is described from the Thousands Islands reef complex, West- Java, Indonesia. The new species is compared with all other Agelas species occurring in the Indo-West Pacific region. The new species differs from these other species by the overall morphology and the size of the verticillated acanthostyles. Surprisingly, this is only the second Agelas species ever described from Indonesia.

Tetractinellid and hadromerid sponges of the Sultanate of Oman Naturalis
Soest, R.W.M. van; Beglinger, E.J..
The Sultanate of Oman harbours rich populations of sponges, especially in the four coral reef areas (Musandam Peninsula, Muscat coast & Daymaniyat islands, coasts of Masirah Island, and the Khuriya Muriya Islands). Up till now, apart from a few incidental samples, the sponges of Oman were known only from five dredge stations made by the John Murray Expedition 1933-1934 off the south coasts of Oman, near the Khuriya Muriya Islands, between 13.5 and 1415 m. Descriptions of the sponges obtained in these dredges were published by Burton (1959) and the specimens are deposited in the collections of the Natural History Museum, London. To complement these dredge samples, we recently obtained samples collected by SCUBA and shore collecting, mostly from the...

The layered structure of bones of birds as a possible indication of age Naturalis
Soest, R.W.M. van; Utrecht, W.L. van.
A method of age determination, new in birds, is described. The method has been derived from similar methods commonly used to determine age of fishes, amphibians, reptilians, and mammals. It consists of demonstrating, by preparation of transverse transparent sections, the presence of annual deposits in the periosteal zone (= zone of outer circumferential lamellae) of bone. Evidence is presented that the layered structures in the periosteal zone are indeed annual and thus related with age.

Monanchora stocki n. sp. (Porifera, Poecilosclerida) from the Mid-Atlantic islands Naturalis
Soest, R.W.M. van.
A new species of the tropical-subtropical genus Monanchora Carter, 1883, is reported from São Tiago (Cape Verde Islands) and Ascension Island. The new species, M. stocki n. sp., is compared with related Atlantic and Indo-Pacific species, viz. Caribbean M. arbuscula (Duchassaing & Michelotti, 1864) (senior synonym of Echinostylinos unguiferus De Laubenfels, 1953, and Monanchora barbadensis Hechtel, 1969), and Indo-Pacific M. unguiculata (Dendy, 1922). The new species stands out among Monanchora species by the longer and more pointed teeth of its spatulate-unguiferate chelae, which in extreme cases almost meet. The structure of the chelae of Monanchora species of various parts of its range are compared with that found in some other (? related) genera,...
