Superfamily PASIPH^OIDA Borr. 



Family Pasiph^idae. 



The family Pasiphseidae includes at present seven genera: Pasiphcea Sav., Parapasiphae 

 S. I. Smith, Dantecia Caullery, Sympasiphcea Alcock, Orphania Bate, Psathyrocaris W.-Mas. 

 and Leptochela Stimps. Pasiphcea Sav. is a cosmopolitan genus, the 26 species having been 

 observed in all seas of the world. Of the 6 species of Parapasiphae two occur in the Andaman 

 and Arabian respectively Laccadive Sea, one occurs off the west coast of California, while the 

 three remaining species are found on the east coast of the United States and in the North 

 Atlantic, one of the latter even at Cape Point. The 5 representatives of the genus Psathyrocaris 

 are all indopacific, excepting the variety atlantica Caull. of Psath. fragilis, which variety 

 inhabits the Gulf of Gascony. Of the 7 species of Leptochela two are found in the West Indies, 

 while the rest are distributed throughout the Indopacific. The three last genera Dantecia, 

 Sympasiphcea and Orphania are represented each by one species, found respectively in the 

 Gulf of Gascony, the Arabian Sea and south-east of New York. 



The species, collected by the "Siboga", belong to the genera Pasiphcea, Psathyrocaris 

 and Leptochela. Of the genus Leptochela not only a nice new form was discovered, but of the 

 other species, Lept. robusta Stimps., no less than 86 specimens were taken, of which 61, 

 collected north of Waigeu-island, are adult, so that I was enabled to contribute rather largely 

 to the knowledge of this interesting animal, that hitherto was rather insufficient. Of the genus 

 Pasiphcea Sav. 5 species were captured, unfortunately, however, 3 are represented by a single 

 young specimen, so that it proved impossible to determine them with certainty : the single 

 specimen of Psathyrocaris is rather much mutilated.
