of Florida. The fourth, Sic. laevigata Stimps., occurs also in the sea of the Antilles and on 

 the coasts of Florida, and it ranges northward to Charleston, S. C. 



Three species are known from the tropical and subtropical seas on the west coast of 

 America. Sic. penicillata Lock, occurs in the Gulf of California and on the coast of Lower 

 California, while the two others, affinis Fax. and picta Fa.x., are found on the west coast of 

 Central America : Sic. Edivardsi Miers from the Antilles is represented on the west coast by 

 the former, while Sic. picta is the representative both of the atlantic Sic. dorsalis King.sley 

 and the indopacific Sic. laevis Sp. Bate. 



A dozen of species of Sicyonia are found in the Indopacific, including the 4 new species 

 discovered by the "Siboga". Sic. laiicifer (Oliv.) is distributed from Japan (Sagami Bay, Kagoshima) 

 and the Arafura Sea, south of Papua, to Penang, the Gulf of Manaar, the Maldives and to the 

 Red Sea; it is one of the nine species that w'ere captured by the "Siboga", a specimen having 

 been taken in the Bay of Pidjot, Lombok. Sic. cristata de Haan occurs on the coast of Japan 

 and is recorded by Pearson from Ceylon, but this species is perhaps identical with Sic. lancifer. 

 Sic. trispinosa. a new species, that bears a close resemblance to the mediterranean Sic. carinata 

 Olivi, but that has a much smaller size, was discovered at the Paternoster-islands and in Molo- 

 strait. Sic. ocellata Stimps. ranges from Thursday Island to Hongkong, Singapore and Ceylon. 

 Sic. bispinosa de Haan, hitherto only known from Japan, was captured off North Ubian in the 

 Sulu Sea. Sic. laevis Sp. Bate was taken by the "Challenger" North of New Guinea, by the 

 "Siboga" between the islands of Ceram and Burn and is recorded by Miss Rathbun from the 

 Hawaiian Islands. Sic. parvula de Haan, hitherto only known from Japan, was captured near 

 Salawatti and off the Jedan Islands by the Aru Islands. The new Sic. rcctirostris was taken 

 in Sanana-bay, east coast of Sula Besi and Sic. fallax, which is also new to science, was 

 discovered near the Sulu-islands ; the latter is closely related to Sic. longicatida Rathb., which 

 is only known from the Hawaiian Islands. Sic. ftircata Miers occurs at the Sulu-islands. The 

 new Sic. dc7itliopkila, finally, was taken off the Kei-islands. Two unnamed species have been 

 described by W. A. Haswell from specimens occurring on the east coast of Australia; one of 

 them, from Port Jackson, is probably identical with Sic. ocellata Stimps. 



When Sic. ftircata is included, all the indopacific species of Sicyonia prove to occur in 

 the East Indian Archipelago, except only Sic. longicaiida Rathb. and Sic. cristata de Haan. 



It is quite remarkable that all the species captured by the "Siboga" are represented in 

 the collection only by one or two specimens, excepting Sic. parviila, of which nine specimens 

 were taken. 



Most species of this genus seem to occur in rather shallow water. Sic. carinata Olivi 

 e. g. was taken in Goree Bay between 9 and 1 5 fathoms, the variety americana at a depth 

 of 2,5 fathoms; Sic. Edwardsi and Sic. brevirostris are not found deeper than 27 resp. 35 

 fathoms, Sic. laevigata., trispinosa, lancifer^ ocellata^ penicillata and rcctirostris are also only 

 known from shallow water and of Sic. bispinosa a specimen was captured by the "Siboga" at 

 the surface. Sic. laevis was taken by the "Challenger" at 150 fathoms, but by the "Siboga" 

 in water of 36 meter. 



Other 'species, however, are found in considerably deeper water. The new Sic. fallax
