3. Trematomus brachysoma, PappenL (PL n, tig. 3). 



A specimen of 170 mm. in total length, stranded on an ice Hue in 67° 24' S., 177° 

 34' W. A water-colour sketch made by Mr. Lillie shows the body purplish gray, and 

 the fins blue, with the dark spots of the same tint as the colour of the body. 



4. Trematomus bemacchii, Bouleng. (PI. i, fig. 1). 



Cape Evans and off Cape Adare, 45 to 50 fathoms; bottom shingle. 



5. Trematomus hansoni, Bouleng. (PI. i, fig. 2). 



A large number of examples of this and the preceding species were caught in 1911 

 at the winter quarters, Cape Evans, by means of a fish trap made of wire netting 

 stiffened by iron hoops and bars, which was lowered through holes in the ice. It was 

 noted that when a new hole was tried one or two good catches would result, and then 

 no more at all. perhaps because the attention of Weddell Seals had been attracted. 

 The fish were eaten and had a distinctly sweetish taste. 



Three water-colour sketches were made by Dr. Wilson to show the natural 

 coloration ; two of these are reproduced on Plate I. 



6. Trematomus loenribergii, Eegan. v 



Trematomus loenribergii, Regan, Trans. 1!. Sec. Edinburgh, xlix, 1913, p. 263, pi. viii, f. 4. 



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

 3 to 3^ in length of head, interorbital width 6 to 10. .Maxillary extending to below 

 anterior t or -g- of eye; upper surface of head to nostrils, cheeks and opercles scaly. 

 10 to 13 gill-rakers on lower part of anterior arch. Dorsal v— VII, 31-35. Anal 31-35. 

 Pectoral nearly as long as head ; pelvics reaching anal. Caudal rounded or subtruncate. 

 Caudal peduncle as long as or longer than deep. 60 to 75 scales in a longitudinal 

 series, 34 to 40 in upper lateral line ; lower lateral line, when developed, sometimes 

 with as many as 15 tubules. Body with irregular dark cross-liars. 



Several examples up to 190 mm. in total length, from off new land south of 

 the Balleny Islands, at a depth of 200 fathoms, from near Inaccessible Island, 222 to 

 241 fathoms, and from the entrance to McMurdo Sound, 77° 13' S., 1G4° 18' W., 

 207 fathoms.
