Colour -The upper and lateral parts of the head and body dull lavender- 
purple, shaded with brownish red ; the under surface of the head the sides o( 
die body interiorly, and the belly, light wood-brown tinted with flesh-red, 
which tint is very strong on the anterior portion of the head -d the hinder 
edges of the fins. On the upper and lateral parts of the head and body and 
also on several of the fins, the ground colour is much broken by a profusion 
of small circular white spots, and a great number of narrow vertical lines 
which commence at the centre of the back and terminate at the belly. The 
spots are smallest and most numerous on the head and upper surface of the

edge ; the second dorsal, the anal, and the ventral fins are without spots.

behind the angles of the mouth ; pupil transversely oval ; temporal orifice

the middle of the hind head, slightly arched and strongly keeled ; back, 
posterior to dorsal fin, fiat and depressed. Sides of body irregular from two 
distinct longitudinal keels, which commence together a little in front of, 
and considerably above, the upper extremity of first branchia, and recede 
a little from each other as they proceed backwards. 01 these, the lowermost
