2. Pliniragramma, Bonleng., 1902. 

 ''■ Southern Cross" Pisces, p. 187 (1902). 



Closely related to Trcmatomus, differing especially in the very thin cycloid scales, 

 the absence of pitted or tubular lateral line scales, and the feebly ossified skeleton, with 

 parapophyses developed only on the posterior prsecaudal vertebrte. 



Coasts of the Antarctic Continent. 



BouLENGER has placed this genus in the family LeptoscopidtB, but it has no affinity 

 with Leptoscopiis, and, on the other hand, is very near to Trenmtomus. A comparison 

 of Pleurac/ramma antarcticnm with Trematomns nctvnesii shows a very close agree- 

 ment in external and internal characters, even to the number of fin-rays and vertebrse ; 

 the pectoral arch is precisely similar. In Pleura;/ ram ma the two lateral lines are 

 marked by scales with notched posterior edges, or, if the scales have been lost, by series 

 of pores.

Depth of body 5 to 6 in the length, length of head 3.1 to 4. Diameter of eye S^ to 

 3 J in the length of head, interorbital width 5 to 6. Lower jaw projecting ; maxillary 

 extending to below anterior \ of eye ; upper surface of head naked ; cheeks and opercles

Here described from several specimens, 150 to 200 mm. in total length, including 

 the types of the species from Victoria Land [Sovtlion Cross) and examples from near 

 Cape Armitage, Ross Island, and from south-west of the Balleny Islands (Z)i.9cot'er3/).
