This fish agreeing in its general form, the disposition and number of its fins, as well as in most other respects, 
with the one last described, it will be sufficient to mention the most material circumstances in which 
they differ. 
The head towards the point is more ovate, and the mouth higher, the eyes oval, the posterior nostril much 
larger than the anterior; the last of the three rays of the first dorsal fin is not distant from the other; the 
pectoral fin is more central. The second dorsal fin only is streaked, as in the former, the anal and caudal 
being without streaks. 
The colour here is not dusky but greyish; and the spots which in the former, were below the pectoral fin, 
are here above it, and of a fainter yellow. The narrow stripes, on the second dorsal, are yellow and white, like 
those on the anterior fin.
