dle of the upper eye, and increasing in the height 
of its rays towards the middle, decreases from that 
point gradually towards the caudal fin, a short dis- 
tance in front of which it terminates. 
The Pectorals are situated just beneath the pos-

The Ventrals, of moderate size, arise on the same 
plane with the Pectorals. 
At the commencement of the Anal fin, a project-

The Caudal fin, when expanded, is one third 
deeper than high. 
The rays are: D. 65; P. 10; V. 6; A. 48; C.
