232 CRUSTACEA MALACOSTRACA. III. 



-4- ro to -T- 1-4. Ohlin has recorded it from a place west of Spitzbergen: L,at. 76^6' N., L,ong. i2io' E., 

 929 fath., temp, -f- 1-3; Dollfus had it from a place in L,at. 7928' N., Long. 32o' E., 990 fath. 



G. stygia is thus only known from the cold area in depths from 293 down to 1309 fath., 

 temp. -f- 0-5 to -4- 1-4. - - When Tattersall (Isopoda, 1905) referred with a query a "larval female" taken 

 west of Ireland to this species, because it was blind and similar to Sars' figure of the larva, the 

 determination was certainly wrong; it may also be taken into account that above I have described two 

 new blind species from the warm area.
