| The Sumba-Expedition undertaken by Dr. E . Sutter of the Naturhistorisches Museum of Basle and Dr. A . Bühler of the Museum für Völkerkunde of the same town, visited the Lesser Sunda Islands, Indonesia, in 1949. Dr. Sutter, the zoologist, stayed in the islands from 19 May to 26 November; most of the time was spent by him in Sumba (21 May-31 October), and extensive collections were made there, among which a most interesting material of Decapod Crustacea, which forms the subject of the present paper. A few Crustacea were collected on the islands of Sumbawa (on 19 May) and Flores (19 and 21 November). The animals taken at Flores belong to species also obtained in Sumba and will be treated here with those; at Sumbawa two hermit crabs belonging to the species... |

| Dedicated to Professor H. Boschma on the occasion of his seventieth birthday. INTRODUCTION The family Burhinidae or Stone Curlews, consists of large ploverlike birds which have no hind toe, long yellow legs with thickened tibiotarsal joints, hence the sometimes used popular name of "thickknee". The head is relatively big and very round and the eye is yellow, large and very striking. The bill is short and stout. The plumage is very cryptic when the bird is at rest, but in flight or in postures with wings raised a rather striking contrasty pattern becomes visible in the wing. All members of this family are nocturnal in their habits and during the day time they often squat on the ground among rocks and vegetation and are then difficult to spot unless they... |

| Up to the late sixties of this century the number of species of the genus Uca occurring on the East and Gulf coasts of North America seemed rather well established. Usually ten species were listed: U. burgersi Holthuis ( = U. affinis (Streets)), U. leptodactyla Rathbun, U. minax (Le Conte), U. pugilator (Bosc), U. pugnax (Smith), U. rapax (Smith), U. speciosa (Ives), U. spinicarpa Rathbun, U. subcylindrica (Stimpson) and U. thayeri Rathbun. Subsequently, however, some uncertainty arose about the number of fiddler crab species of the Gulf coast area. Barnwell (1968) mentioned an undescribed species from Ocean Springs, Mississippi, and Salmon and co-workers described no less than three new Gulf coast species of Uca (Salmon & Atsaides, 1968; Novak &... |

| In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella. Transferred to Tethysbaena are: M. argentarii Stella, 1951; M.... |

| A new alpheid shrimp, Thuylamea camelus gen. nov. & spec. nov., from Dong Hoa, a coastal community of Can Gio district, and northwest of Vung Tau (Cap St. Jacques), Vietnam, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. It has the postero-dorsal margin of the carapace armed with two high and short crests which are slightly outward inclined and directed backward, and between these crests with a low but distinct conical spine, and an elevated conical boss in the anterior median area slightly behind the anterior margin of the first abdominal somite. |

| Through the kindness of Mr. Philip Chapman of Culford, Bury St. Edmunds, Suffolk, it was made possible for me to examine a male and a female of a species of cavernicolous crab from the Western Highlands of Papua New Guinea, collected there by Mr. N. Plumley. The species proved to be new to science and its description is given below. A recent revision of the New Guinea freshwater crabs (Bott, 1974) listed 13 certain and 3 dubious species from the island. These 13 species belong to 3 genera (Rouxana Bott, 1969: 5 species; Geelvinkia Bott, 1974: 3 species; and Holthuisana Bott, 1969: 5 species). The first two genera and the nominate subgenus of the third are confined to New Guinea. All three genera belong to the family Sundathelphusidae Bott, 1969. The new... |

| INTRODUCTION The present paper deals with some morphological features found in the species of the genus Euchirella Giesbrecht, 1888, family Aetideidae. In the course of my studies on the genus, I noted that the structures situated on the anterior surface of the endopodites of the first pair of swimming legs, which will be described below, have never been given the attention they obviously deserve. In none of the principal works on Calanoida, e.g., Scott (1909), Sars (1924-25), Rose (1933), and Brodskii (1950) these structures are dealt with in the text. The same holds for the important reviews by Vervoort (1957, 1963), and Tanaka & Omori (1969). Although most authors somehow figure a row of spinules on the tubercle of the endopodite, their drawings are... |

| Progress in classification of Chelicerata has been thwarted especially by two factors, viz., the concept of mites as one monophyletic group, and the opinion that this group consists of species with a highly modified plan of construction and without any trace of true segmentation. The only characters which are generally shared by all groups of mites refer to the presence of a gnathosoma (i.e. the cone-shaped, movable structure comprizing the mouthparts), and the occurrence of a larva with only three pairs of legs (the last-mentioned character is also found in Ricinulei). A comparative morphological study of the gnathosoma (Van der Hammen, 1970b, 1972) has, however, demonstrated that two fundamentally different types can be distinguished, which must be the... |

| A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae... |

| The earliest known crabs are of Early and Middle Jurassic age; in general, they are rare. Here we describe a new species of homolodromioid from the late Bathonian of Sarthe (France), based on a single dorsal carapace, Tanidromites raboeufi n. sp. This specimen has mostly well-preserved cuticle, and shows two episkeletozoans (bryozoan colonies) on its dorsal side, which is unique amongst early brachyurans (Early and Middle Jurassic). These bryozoans are identified as juvenile colonies of the morphogenus Berenicea (sheet-like tubuluporines), typical encrusters of hard substrates. Their presence directly on the carapace crab shows that they were closely cohabitating with this early brachyuran in its palaeoenvironment. One of these colonies appears to have... |

| Due to the kindness of Mr. Y. Therezien, Ingénieur-hydrobiologiste of the Centre Technique Forestier Tropical at Tananarive, Madagascar, the Rijksmuseum van Natuurlijke Historie received at several occasions freshwater Crustacea from Madagascar. Two previous reports (Holthuis, 1964, 1965) dealt with the crayfishes and the atyid shrimps of these collections. Among the fresh-water Palaemonid prawns a new species of Macrobrachium was found, which is the subject of the present note. It is a great pleasure to dedicate this beautiful species to Mr. Therezien. Macrobrachium therezieni new species River of Maningory, Fénérive district, Tamatave province, eastern Madagascar; 16 February 1961; Y. Therezien, no. 9. — 1 adult male (holotype); Rijksmuseum van... |

| A new species of gall crab is described from the free-living stony coral Trachyphyllia geoffroyi. Specimens were collected during field work in Lembeh Strait (Indonesia) and of Kudat (Malaysian Borneo). This new species, here named Lithoscaptus semperi sp. n., is the ninth species assigned to the genus. It can be separated from its congeners by not having the internal orbital angle extending beyond the external orbital angle, and by the stout female P2 merus with prominent distomesial projection. In addition, the carapace surface appears smooth, despite having small tubercles on the anterior half, and is without noticeable spines, other than those on the frontal margin. The distinctive carapace pattern in life is a diagnostic character in male specimens. |
