| The chirostyloid squat lobster Pristinaspina gelasina from the Upper Cretaceous of Alaska is most closely related to members of the genus Kiwa (Kiwaidae) as indicated by the presence of supraocular spines, a medially carinate rostrum and similar carapace groove patterns. Evidence from morphology, stratigraphic position and molecular divergence estimates of extant chirostyloids supports its position in the stem of Kiwaidae. Pristinaspina, however, also differs significantly from kiwaids and is here assigned to a new family, Pristinaspinidae. The chief distinction between the free-living pristinaspinids and vent- or seep-associated kiwaids (and an important synapomorphy of the latter) is the enlargement of the metabranchial regions in kiwaids, which meet in... |

| A NEW SPECIES OF SULCIA In 1962, Dresco described the first representative of the genus Sulcia from the Greek mainland, Sulcia lindbergi. Recently, Brignoli (1968a) considered this species a subspecies of Sulcia cretica Fage. The genus is also known from Dalmatia, Hercegovina, Montenegro, and some adjacent islands (Kratochvil, 1938) and from the Island of Crete (Fage, 1945). In January 1969, my husband P. R. Deeleman, had the opportunity to visit the Koutouki Cave near the village of Ljopessi (officially also called Peania), situated at approximately 20 km west of Athens. This visit was made possible by the assistance of Mrs. A. Petrochilos and Mr. A. Kanellis, to whom we feel very much obliged. In this cave a new species of Sulcia was collected. The cave... |

| The author deals with taxonomy, character variation, phylogeny and biogeography of Heterometrus, a scorpion genus occurring in Southeast Asia. The taxonomic value of 131 characters is studied, including 75 biometric ones; 72 characters are selected to be used in the present revision for purposes of classification. In the numerical analysis and in the study of descriptive characters, specimens are clustered polythetically; this method allows variation as observed in the taxa, the sharing of the total set of taxon characteristics not being absolutely required. A total of 21 species (4 new) and 31 subspecies (16 new) are discriminated, classified in five subgenera, two of which are new. The African genus Pandinus Thorell is found to be the sistergroup of... |

| We describe a possible new defensive behaviour of larval stages of mantis shrimps (Stomatopoda). Mantis shrimp larvae are rarely observed in nature, thus the study is based on postures of museum material and functional morphological aspects. Specimens described here are tightly enrolled, their pleon is bent forward,and the telson is locked into the frontal margin of the shield. This margin has two lobes into which the two posterolateral spines of the telson fit. The shield shows further adaptions to enrolment; e.g., the ventral gape of the shield perfectly matches the width of the pleon and leaves no major gaps when the pleon is bent forward. Based on these observations, we briefly discuss the possibilities to infer behavioural aspects from functional... |

| A comparative study is made of four chelicerate classes: Apatellata (Solifugae and Pseudoscorpionida), Arachnida s. str. (both groups of Uropygi, i.e. Holopeltida and Schizomida, Amblypygi and Araneida), Scorpionida and Xiphosura. Methods, principles and terminology, adopted in this paper, correspond with those of parts I -111 of the present series of comparative studies in Chelicerata. Special attention is paid to segmentation of the body, respiratory organs, orifices of coxal glands, mouthparts, and appendages. The evolution of these structures is studied, and the relationships of the chelicerate classes and subclasses are reinvestigated and discussed. |

| Pagurus loxochelis a été décrit et figuré par C. Moreira (1901, p. 24 pl. 2 fig. 1, 1a-f) d'après un unique exemplaire mâle provenant de Bahia. L'auteur ne plaçait pas sans hésitation cette espèce dans le genre „Pagurus" Fabricius (= Dardanus Paulson) 1). Il constatait en effet que le flagelle des antennes était orné de longues soies, alors qu'il était nu chez les autres "Pagurus". Considérant cependant que Miers (1881, p. 275-276) avait décrit Pagurus imperator et P. granulimanus comme possédant des antennes, non pas nues, mais faiblement ciliées, il choisissait d'étendre l'acception du genre, plutôt que d'en décrire un nouveau pour une unique espèce. Précisons immédiatement que la raison invoquée par Moreira pour rattacher P. loxochelis au genre... |

| Les espèces du genre Anthessius Della Valle, 1880, sont associées de façon très préférentielle à deux classes de Mollusques: les Pélécypodes et les Gastéropodes. Notre connaissance taxonomique du genre progresse actuellement de manière très rapide. Il y a cinq ans seulement, on ne connaissait que 11 espèces d'Anthessius; Illg, en 1960, en énumérait 17; récemment, Stock, Humes & Gooding (1963) en dénombraient 23. Ces derniers auteurs intégraient, pour la première fois, dans le genre Anthessius, une espèce malaise, décrite par Leigh-Sharpe, en 1934, sous le nom de Lichomolgus brevicaudis. La description originale de cette espèce, beaucoup trop insuffisante, n'en permettant pas une détermination exacte, son appartenance au genre Anthessius fut établie par... |

| INTRODUCTION In this paper the species of spiders belonging to the families Lycosidae and Pisauridae, known from the Netherlands, are described and figured. In addition a number of species, which possibly may occur in the Netherlands though they have not yet been found here hitherto, are mentioned in the keys. In order to make the keys useful also for identifying immature specimens, I have based these keys not only on the well-known differential characters in the adult sexual organs, but also, as far as possible, on characters derived from colour-pattern and chaetotaxy. The system of notation, used to indicate the situation of the spines on palps and legs, is briefly stated as follows (Wiebes, 1956, pp. 408, 409) : d, 1', 1", v', and v" indicate dorsal,... |

| During the years 1942-1949 investigations were made on the fauna of the greenhouses of several Botanic Gardens in the Netherlands, on the initiative of Dr. A. D. J. Meeuse; material was also collected in greenhouses belonging to other institutions and in those kept for commercial purposes. A list of publications based on the results of these investigations has been given by Van der Hammen (1969). In a number of greenhouses the terrestrial amphipod, Talitroides alluaudi (Chevreux), was collected. This paper reviews the distribution of this species in Dutch greenhouses, and gives a survey of the occurrence of terrestrial species or the genus Talitroides in Europe. The genus Talitroides was erected by Bonnier (1898) for a species later named T. bonnieri by... |

| Since 1870 it has been a matter of debate among araneologists whether Meta mengei, described by Blackwall in that year, and separated by him from Meta segmentata (Clerck, 1757), is a real species or only a variety. In order to find an answer to this question I give an historical survey of the views of the most important authors concerning this matter, followed by a discussion of the peculiarities generally regarded as characters distinguishing the two species or varieties, and a short account of my own investigations. 1757. Clerck figures and describes a species of spiders of which in the beginning of September he observed a great number ; he names it (Araneus) segmentatus. 1758. Linnaeus publishes a concise description of the same species and names it... |

| Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae) Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and... |

| A small collection of copepod samples from several wells in the Canterbury region, South Island, was examined. It contained a few cosmopolitan cyclopoid species, three interesting harpacticoids, as well as two new cyclopoid genera. The latter are presented in this paper, together with a redescription and first description of the male of Goniocyclops silvestris Harding, 1958, a cyclopoid species previously known only from North Island. Both new genera are from the Diacyclops-Acanthocyclops complex. Abdiacyclops gen. nov. is easily distinguishable from the complex by its unique swimming legs segmentation formula (2/2, 3/3, 3/3, 3/3), and is so far monospecific and known only after females. The most important characters of the second new genus, Zealandcyclops... |
