1 Localities: N. longipcs. Port Churruca, Straits of Magellan, 02-27; Sandy Point, Straits of Magellan, 

 01-3, 01-35; Albatross station 2770, near lliilv Point, and Cape V/atchmap, east coast of I'atagonia, 01-55, 

 02-19, 02-20, 02-23. N. tessellata, Port Grappler, 01-5, 01-4; Sandy Point, Straits of Magellan, 01-6, 01-47; 

 Laredo Bay, Straits of Magellan, 01-19; Mavne Harbor, Patagonia, 02-40; Port Churruca, Straits of Magel- 

 lan, 01-54. 



No difference could be seen in the average extension of the maxil- 

 lary farther under the eye with age, but it varied much more in older 

 specimens and was greatest among the very young, with large eyes. 

 Tlie highly variable depth varies between 0.15 and 0.20 of the body 

 length of specimens 70 and 150 mm.; those above 150 mm. vary 

 between 0.18 and 0.22, tlius including that given for N. wiltoni Regan. 



15. NOTOTHENIA CANINA Smitt. 



Notothenia tessellata, iorrasi canvna Smitt, Bih. Svenska Akad., vol. 23, IV, No. 

 3, 1897, p. 25, pi. 1, figs. 10, 11; pi. 2, figa. 20-22. Port Gallegos, Patagonia. 

 Notothenia canina Boulenger, Southern Cross, 1902, p. 183 (after Smitt). 



Tlie foUowhig characters are taken from Smitt's ^ paper on Noto- 

 tlienia, as the species has not been seen by any other author. These 

 are changed from measurements in hundredths of total length to 

 those in hundredths of body length, so as to compare with measure- 

 ments of the other species. The large number of scales m the upper 

 lateral line would appear diagnostic save for the fact that Smitt gives 

 a variation of 25 scales in 15 specimens of N. longipes, whereas the 

 greatest variation among 30 of our specimens of N. longipes is only 9 

 scales. The occasional extraordmary range of variation in his work 

 casts some suspicion on his identifications. 



Head in hundredths of length to base of caudal 0.27 to 0.29; eyes 

 0.06 to 0.075; snout 0.06 to 0.07; width of interorbital space 0.05; 

 length of maxillary 0.097 to 0.12; of mandible 0.13; length of anal 

 base 0.45 to 0.48; height of first dorsal 0.10; of second 0.115; of 

 anal 0,10 to 0.11; of pectorals 0.22 to 0.255; of ventrals 0.17 to 

 0.19; depth of body 0.15 to 0.17; of caudal peduncle 0.075; D. VI, 

 32 or 33; A, 30 or 31; pectoral rays 26 to 28; scales with pores in 

 upper lateral line 62 to 64; m lower 7 to 12; in lateral series 68 to 71;
