Arr. XXVII.—On a new Fish. By W. D. Caurszzzr, C.E., F.G.S. 
(Read before the Westland Institute, 8th January, 1879.] 
Tue following description is of a new genus of fish, four specimens of which 
were obtained by myself on the 18th of May last, on the Hokitika beach. 
It has very marked peculiarities. The single dorsal, and the stout spinous 
rays in both it and the anal, connected by a perforated membrane, presents 
entirely distinct characters from any previously described genus. The most 
nearly allied appears to be the genus Drama. There is a possibility that 
the specimens obtained are young, but the characteristic points described 
below appear uniformly in them all. "E 
Fam. Scompripz. 
Group 5. Coryphenina. 
Genus nov. Discus. 
Body compressed and elevated ; general form circular-pointed at snout 
and tail. Head and lower portion of body scaleless, minute scales on
