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...

A Checklist of the Curaçao Sponges (Porifera Demospongiae) including a pictorial key to the more common reef-forms Naturalis
Soest, R.W.M. van.
Although sponges are by no means unimportant organisms, in biomass and diversity, of the Curaçao coral reefs, very few scientific studies have been undertaken in this area involving sponges. To date, apart from taxonomie studies by Arndt (1927) and myself (Van Soest, 1978, 1980), only the boring sponges received attention (e.g. studies of De Groot, in progress). The main reason for this, no doubt, is the confused taxonomy of West Indian sponges. While taxonomie studies are in full progress (but are necessarily slow), it is now already possible to present sufficient data to allow certain identification of the more common reef forms by non-taxonomists for ecological or other purposes. It is one of the objects of the present paper to provide these data; they...

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.

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...

A new sponge Desmapsamma vervoorti spec. nov. (Poecilosclerida: Desmacididae) from Indonesia Naturalis
Soest, R.W.M. van.
A new poecilosclerid sponge species Desmapsamma vervoorti spec. nov. is described from several Indonesian localities: Ambon, Jedan, Salayar, Komodo, Java, and Irian Jaya. The species was earlier reported from several Indo-Pacific localities as D. anchorata (Carter, 1882), a common Caribbean shallow water species. Comparison with Caribbean specimens makes it clear that Indo-Pacific specimens demonstrate small but consistent differences.

A new sublithistid sponge Monanthus ciocalyptoides n.sp. (Porifera, Halichondrida), from the West Indian region Naturalis
Soest, R.W.M. van; Zea, S..
Monanthus ciocalyptoides n. sp. is described from two localities in the West Indian region, viz. the Saba Bank (17°25’N 63°33’W) and the Colombian Caribbean (11°20’N 74°09’W). The genus was hitherto known from South African waters only, by the type-species M. plumosus Kirkpatrick (1903). The systematic status of the new species and the genus as sublithistid members of the order Halichondrida is discussed.

A revision of the genera Salpa Forskål, 1775, Pegea Savigny, 1816, and Ritteriella Metcalf, 1919 (Tunicata, Thaliacea) Naturalis
Soest, R.W.M. van.
Based on material from all oceans the Salp genera Salpa, Pegea and Ritteriella are revised. Particularly the study of the number of muscle fibres has shown that Salpa maxima var. tuberculata, the subspecies Pegea confoederala bicaudata and the generally synonymized species Ritteriella retracta are valid taxa, which are given the status of species. The existence of two groups of individuals differing biometrically within the species Salpa aspera and Ritteriella retracta is reported.

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...

Affinities of the family Sollasellidae (Porifera, Demospongiae). I. Morphological evidence Naturalis
Soest, R.W.M. van; Hooper, J.N.A.; Beglinger, E.; Erpenbeck, D..
Comparison of Sollasella digitata Lendenfeld, 1888, up until the present assigned to its own family Sollasellidae Lendenfeld, 1887 in the order Hadromerida, and Raspailopsis cervicornis Burton, 1959, assigned to Raspailiidae Nardo, 1833 in the order Poecilosclerida, leads to the conclusion that both should be considered congeneric and are best assigned to a single genus Sollasella. This conclusion is based on examination of habit and skeletal characters of the type material of S. digitata and both type and freshly collected material of S. cervicornis. The conclusion is strengthened by the discovery of a new species, Sollasella moretonensis n.sp. collected in North Australia (primarily in the northeastern coast, but also an isolated record from the...

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...

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.

Deficient Merlia normani Kirkpatrick, 1908, from the Curaçao reefs, with a discussion on the phylogenetic interpretation of sclerosponges Naturalis
Soest, R.W.M. van.
A specimen of the sclerosponge Merlia lacking a basal skeleton of calcareous chambers (corresponding to the description of Merlia deficiens Vacelet, 1980) is reported from the underside of the coral Agaricia at a depth of 10 m on the reef of Curaçao, Netherlands Antilles. Its spiculation is identical to Merlia normani Kirkpatrick, 1908 specimens with the basal skeleton, from which it is concluded that M. deficiens and M. normani are probably conspecific. The phylogenetic significance of a sclerosponge with an unstable calcareous skeleton is discussed and in accordance with Vacelet (in press) it is postulated that sclerosponges are polyphyletic. It is suggested that sclerosponge skeletons are an ancestral character for a large part of the Demospongiae. The...

Didiscus verdensis spec. nov. (Porifera: Halichondrida) from the Cape Verde Islands, with a revision and phylogenetic classification of the genus Didiscus Naturalis
Hiemstra, F.; Soest, R.W.M. van.
A new species of the circumtropical/subtropical genus Didiscus Dendy, 1922 is described from the Cape Verde Islands. Based on a phylogenetic analysis of all known species of the genus, using morphological and microscopical (including SEM) characters, it was demonstrated that the new species is closest to the eastern Mediterranean D. styliferus Tsurnamal, 1968.
