NOTOTHENIIDAE 75 



from Island Harbour, Patagonia; another was from Gregory Bay; and seven were from 

 'Albatross' Station 2771, at a depth of 50! fathoms. I have examined one of these 

 last, but it is in such a poor state as to be useless for comparison. After considering 

 Thompson's description and figure, I agree with Regan (1916, Ann. Mag. Nat. Hist., 

 Ser. 8, xviii, p. 379) that his type at least is referable to the species here identified as 

 N. brevicauda. It is probable, however, that the examples taken by the ' Albatross ' in 

 deeper water may have belonged to the form described below as N. guntheri. The type 

 of N. brevicauda from Ushuaia (120 mm. long without caudal), judging from Lonnberg's 

 figure, has an exceptionally short and deep caudal peduncle, but is in other respects 

 similar to specimens identified by Regan as this species.
