variation in the size of the eye, and its diameter is 

 proportionately greater in the younger specimens than 

 in the larger ones. But even in the largest it is distinctly 

 longer than the postorbital portion of the head, as is 

 shown in Giinther's figure. None have any scales on 

 the under surface of the head. 



Localities. South-south-east of Gabo Island, Vic- 

 toria, 176-200 fathoms; 15th February, 1914. 



Eastern edge of Bass Strait, 100-220 fathoms. 



North-east of Babel Island, Bass Strait, 70-100 

 fathoms. 



35 miles south-east of Bruni Island, Tasmania, 150- 

 230 fathoms. 



Great Australian Bight, south-east from Eucla, 250- 

 300 fathoms ; 6th May, 1913. 



Great Australian Bight, south from Eucla, 350-450 

 fathoms ; 14th May, 1913. 



Great Australian Bight, south-west from Eucla, 126 

 45i' E. long., 190320 fathoms; 4th May, 1913.

Br. 6; D.ii/11; P.17; V.7. Three scales between the 

 lateral line and the middle of the first dorsal, and four 

 at the origin of the second dorsal. 



Head and trunk (83 mm.) 2-7 in the total length 

 (228 mm. tail incomplete). Depth (40) 1-2 in the head 

 (50). Eye (19) 2-6 in the head, and subequal to its post- 

 orbital portion; snout (12) 1-5 in the eye, its length a 

 little greater than the interorbital width (11-5). Second 

 dorsal spine (39) as long as the postrostral portion of 

 the head. Pectoral fin (27) 1-8, anterior anal rays (13) 

 3-8 in the head. 



An area on each side of the anterior portion of the 

 snout, and around the nostrils is naked; the rest of the 

 upper portion and sides of the head is covered with scales, 

 though they are widely spaced on the interorbital region. 

 The lower surface of the head is largely naked, but the 

 area between the angle of the mouth and that of the 

 preoperculum is covered with rugose scales. The rostral 

 tubercle is covered with short spiuules, and a median 

 ridge extending backward from it to the level of the eyes
