7. Trematomus pennellii, Regan (PI. in. fig. 2). 



Trematomus pennellii, Regan, Ann. Mag. Nat. Hist. (8) xm, 1914, p. 12. 



Depth of body i\ to 5 in the length, length of head 3^ to Mi. Diameter of eve 

 :;] to ■'<}> in length of head, interorbital width 8 to 10. Maxillary extending to below

 30. Pectoral | or -, length of head; pelvics extending to origin of anal. Caudal 

 subtruncate. Caudal peduncle as long as deep. 52 to 56 scales in a longitudinal scries 

 from above base of pectoral tin to caudal, 32 to 36 in upper lateral line; lower lateral 

 line without tubules. Olivaceous, with two or three series of large dark spots which 

 may unite to form irregular cross-bars. 



Off Cape Adare ; 45 to 50 fathoms: bottom shingle. Five specimens, 100 to 140 

 nun. in total length. 



This species is named after Commander II. L. L. Pennell, k.n. 



8. Trematomus centronotus, Regan (PL [ii, fig. 1). 



Trematomus centronotus, Regan, Ann. Mag. Nat. Hist. (8), xm, 1914, p. 12. 



Depth of body 4 in the length, length of head 3^ to 3f. Diameter of eye :;{ in 

 the length of head, interorbital width 10. Maxillary extending to below anterior [ or 

 .1 of eve; occiput, interorbital region, cheeks and opercles scaly. 14 gill-rakers on lower 

 part of anterior arch. Dorsal v-vi, 32-35: spines stiff, pungent. Anal 29 32. 

 Pectoral ;-; or § length of head; pelvics extending to origin of anal. Caudal peduncle 

 as long as deep. 52 to 56 scales in a longitudinal series from above base of pectoral 

 tin to caudal, 30 to 36 in upper lateral line; lower lateral line without tubules. Large 

 dark -pots uniting to form irregular cross-bars. 



Two specimens, 175 and 210 mm. in total length, from McMurdo Sound. 100 to 

 200 fathoms. 



The pungent dorsal spines distinguish this species from all others of the genus, but 

 it so closely resembles T. pe?inellii in other characters, scarcely differing except in the 

 larger eve. that it is undesirable to place it in another genus.

Notothenia scotti, Bouleng. Nat. Antarct. Exped. Nat. Hist, u, Fish, p. 2, pi. i, f. 1 (1907);
