ANTARCTIC FISHES OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 345 



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

 13 to 16 gill-rakers on lower part of anterior arch. Dorsal V-VII, 36-41. Anal 

 33-36. Pectoral f to |- the length of head, longer than pelvics, which do not reach 

 the vent. Caudal subtruncate. Caudal peduncle about as long as deep. 60 to 68 

 scales in a longitudinal series from above base of pectoral fin to caudal, 38 to 46 in 

 upper lateral line ; lower lateral line usually without tubules. Brownish, with large 

 dark spots or cross-bars ; head often spotted ; fins usually barred with series of 

 dark spots. 



South Georgia ; Graham Land ; Coats Land ; Wilhelm Land ; Victoria Land. 



Here described from several specimens, 160 to 380 mm. in total length, including 

 the types of the species, from Cape Adare, 4 to 8 fathoms, and Duke of York Island, 

 near Cape Adare, 3 to 4 fathoms (Southern Cross), examples from the Discovery 

 winter quarters, Ross Island, and three from Coats Land, Station 411, 74 01' S., 

 22 00' W., 161 fathoms ; temperature 28'9 F. ; trap; March 1904. 



Dr LOXNBERG'S supposed subspecies from South Georgia is fully identical with the 

 typical form. He gives "the number of anal rays as (31) 32-33. but the figure shows 

 36, and in an example that he has kindly sent me I count 35. There is no difference in 

 the shape of the pectoral. 



Dr PAPPEXHEIM has kindly sent me for examination the smallest specimen of his 

 N. lepidorhinus, 160 mm. in total length, which he has noticed as differing from the 

 types in the larger number of dorsal rays (38 instead of 32 or 33). It differs also in the 

 naked snout and praeorbital, shorter pelvic fins, lower lateral line without tubules, 

 foramen enclosed in the hypercoracoid, etc., and is in every way similar to one of the 

 types of T. hansoni, with which I have compared it. 



(8) Trematomus loennbergii, sp. n. (PL VIII. fig. 4.) 



Depth of body 4f to 5 in length, length of head 3 to 3|. Diameter of eye 3 to 4^ 

 in the length of head, interorbital width 7 to 10. Maxillary extending to below 

 anterior of eye ; upper surface of head to nostrils, cheeks, and opercles scaly ; 1 3 gill- 

 rakers on lower part of anterior arch. Dorsal V-VI, 33-34. Anal 31-33. Pectoral 

 as long as or a little shorter than head ; pelvics extending to origin of anal or beyond. 

 Caudal rounded. Caudal peduncle longer than deep. 60 to 70 scales in a longitudinal 

 series from above pectoral fin to caudal ; 36 to 42 in upper lateral line, which ends below 

 posterior rays of dorsal ; lower lateral line without tubules. 



Victoria Land, Graham Land, and neighbouring islands. 



Here described from three specimens, two from the Discovery collection the larger, 

 132 mm. in total length, from south-west of the Balleny Islands, 254 fathoms; the 

 smaller, 65 mm., in total length, from Tent Island, near Ross Island. The third 

 example, also about 65 rnm., is from Seymour Island, and has been sent to me for 

 examination by Dr LONNBERG, who has recorded this species as Notothenia nicolai
