If to 1^ head-lengths behind head. Pectoral f or f the length of head. Grayish or 

 brownish. 



Wilhelm Land, 380 metres. 



Here described from two co-types, 155 and 150 mm. in total length. These differ 

 greatly in form and proportions, as is shown by the accompanying figures, but I cannot 

 doubt that they belong to the same species. 



FIG. 2. Austrolyeichthys brachycephaliu. 



(2) Austrolyeichthys bothriocephalus. 



Ly axles bothriocephalus, Pappenheim, Deutsclte Sudpolar-Exped., xiii., Zool., v. p. 178, pi. x. fig. 2. 



Apparently related to the preceding species, the more slender of the two examples 

 of A. brachycephalus described above showing considerable resemblance to the photo- 

 graph of the type. But this species is said to have more numerous fin-rays, about 110 

 in the dorsal and 90 in the anal. 



Wilhelm Land, 380 metres. 



Total length of the unique type, 181 mm.
