ELLOBIOPSIDAE 313 



authors belong to E. chatloni, the species has a more or less world-wide distribution, as shown on the 

 map in Steuer's (i932Z>) paper. E. elongata Steuer is known from one locality only, in the South 

 Atlantic in the South Georgia region. 



The specimens belonging to the genus Ellobiocystis were all collected in the region from the Bay of 

 Biscay to the Azores. Parallobiopsis is known from the Mediterranean coastal waters of France 

 only. Rhizellobiopsis was found in the material of two stations of the expedition of Prof. Deruguine in 

 the White Sea. These seemingly restricted areas probably do not constitute the real regions of distribu- 

 tion of the genera mentioned here. 



The available data concerning the distribution of the compound Ellobiopsidae seem to point to the 

 fact that all these are of world-wide occurrence. 



Amallocystis racemosus (Coutiere) was found in the region to the north-east of Iceland. The EUo- 

 biopsid mentioned and figured by Bate, and regarded by Coutiere as belonging to A. racemosus, came 

 from the region of the Fiji Islands. 



A.fasciatiis Fage is known from the Pacific (oflr New Zealand and the Fiji Islands), from the Atlantic, 

 and from the Indian Ocean. 



A. capillosiis Fage is known to occur in the Skagerrak (Fage, 1938) and in the Strait of Magellan 

 (specimens dealt with in the present paper). 



The two specimens of A. umbellahis n.sp. are both from the Atlantic, one from the tropical region, 

 east of Brazil, the other from the South Atlantic, west of Capetown. 



The specimens oiA.fagei Boschma dealt with in the present paper were all collected in the southern 

 hemisphere and mostly in the Antarctic region. Some of them are from the South Atlantic : off South 

 Brazil (St. 712), off Patagonia (St. WS 770), and Scotia Sea and off South Georgia (St. 665, 748, 751, 

 766, 1056). Others are from the South Pacific: Bellingshausen Sea (St. 733), and about half-way 

 between New Zealand and Tierra del Fuego (St. 963, 965). Others again are from the South Indian 

 Ocean: south of Australia (St. 892), and south-west of Australia (St. 869, 871, 872). Amallocystis sp., 

 reported upon by Einarsson (1945), occurring in the waters around Iceland, in all probability belongs 

 to A.fagei. It is probable that the specimen mentioned by Macdonald (1927) from Cumbrae Deep in 

 the Firth of Clyde also belonged to the same species. This species then would also have a large area of 

 distribution.
