33 DISCOVERY REPORTS 



170 mm. in total length, stranded on an ice floe in 67° 24' S, 177" 34' W, taken by the 

 'Terra Nova'. 



This species is closely related to T. borchgrevinki, but may be readily distinguished 

 by the larger scales and the lower number of dorsal and anal rays.

Depth of body 3 to 4^ in the length, length of head 3^ to 4. Snout as long as or 

 rather shorter than eye, diameter of which is 3 to 4I in length of head ; interorbital 

 width 5 to 9. Jaws equal anteriorly or lower a little projecting; maxillary extending to 

 below anterior part or middle of eye ; cheeks, opercles and occiput scaly ; interorbital 

 region naked or with a median series of scales; 13 to 15 gill-rakers on lower part of 

 anterior arch. Scales on body ctenoid ; 60 to 75 in a longitudinal series from above base 

 of pectoral fin to caudal ; 30 to 42 in upper lateral line ; lower lateral line usually without 

 tubular scales. Dorsal IV-VI, 34-38. Anal 31-35. Pectoral with 23 to 25 rays, about 

 I length of head, about as long as pelvics, which just reach anal in young but not in 

 adult. Caudal rounded; caudal peduncle deeper than long. Brownish; large dark

The types of the species, 120 to 250 mm. in total length, are from Cape Adare, 10 to 

 16 metres, and from Duke of York Island, near Cape Adare, 6 to 8 metres. Like the 

 previous species, T. bernacchii usually occurs in rather shallow water, but the ' Aurora ' 

 obtained one example from Commonwealth Bay at a depth of 635 to 732 metres. 



Three young specimens (45-47 mm.), from Deception Island, South Shetlands, 

 collected by Mr A. G. Bennett in February 1918, appear to be referable to this species. 

 I have examined the specimen in the Paris Museum (No. 06 — 126), 118 mm. in total 

 length, identified by Vaillant as Notothenia elegans. The fish (No, ?) from Peterman
