-f- ro° to -f- 1-4°. Ohlin has recorded it from a place west of Spitzbergen: Lat. 76°36' N., Long. i2°io' E., 

 929 fath., temp. -=- 1-3°; Dollfus had it from a place in Lat. 79°28' N., Long. 3°2o' E., 990 fath. 



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

 temp. -=- o - 5° to -4- i'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.
