3. Trematomus brachysoma, Pappenh. (PI. 1, fig. 3). 
A specimen of 170 mm. in total length, stranded on an ice floe in Ci 2 AS ivi 
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 bernacchii, Bouleng. (PI. 1, fig. 1). 
Cape Evans and off Cape Adare, 45 to 50 fathoms ; bottom shingle. 
5. Trematomus hansoni, Bouleng. (PI. 1, 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 loennbergiu, Regan. 
Trematomus loennbergii, Regan, Trans. R. Soc. Edinburgh, xu1x, 1913, p. 263, pl. vm, f. 4. 
Depth of body 4 to 5 in the length, length of head 3 to 32. Diameter of eye 
3 to 34 in leneth of head, interorbital width 6 to 10. Maxillary extending to below 
anterior 4 or 4 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—vit, 31-35. Anal 31-35. 
Pectoral nearly as long as head ; pelvics reaching anal. Caudal rounded or subtruneate. 
Caudal peduncle as long as or longer than deep. 60 to 75 seales in a longitudinal 
series, 34 to 46 in upper lateral line; lower lateral line, when developed, sometimes 
with as many as 15 tubules. Body with irregular dark cross-bars. 
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’ 8, 164° 18’ W., 
207 fathoms.
