Pasiphaea Sav. 



The genus Pasiphcra Sav., with which Wood-Mason's genus Phye is united, because in 

 my opinion it should hardly be regarded as a subgenus, includes at present nearly 26 species. 

 The first described. Pas. Sivado (Risso), is the most widely distributed of all. This Pasiphcea, 

 indeed, is well known in the Mediterranean from Nizza and Genua to the coasts of Greece and 

 in the Southern Adriatic, it is rather common off the Portuguese coast and in the Bay of Biscay, 

 but has not yet been observed in the English Channel and North Sea. It is found, on the 

 contrary, in the Bristol Channel, in the Irish Sea, off the west coast of Scotland and Ireland, 

 while it has been taken also, though rarely, off the south and west coasts of Norway. This 

 species, however, occurs moreover in the Red Sea, the Bay of Bengal and the Andaman 

 Sea and has even been dredged off the coasts of Japan '). Pas. sicula Riggio is the second 

 species that inhabits the Mediterranean. Still three other species are found on the west coast 

 of Europe. Pas. principalis^ which has always been confounded with Pas. tarda., until it was 

 distinguished by Oscar Sund in 191 2 as a proper species, has been observed at the north 

 side of the Bay of Biscay, off the south-west of Ireland, south of the Wyville Thomson ridge 

 and off the west coast of Norway to Andenes; it occurs also south of the Faeroes and has 

 even been captured by the "Tjalfe" east of Labrador. Pas. tarda Kroyer occurs in the seas 

 around Greenland and Iceland, has been observed in the Skagerack and seems to occur also 



i) On this occasion I wish to call attention to the fact that an exhaustive description of Pctsipliaa Sivado (Risso) has not yet 

 been published, as far as I am aware, the descriptions, known to me, being all more or less incomplete.
