1870.] SURGEON F. DAY ON INDIAN FISHES. 371 
This fish is very similar to the L. thermalis ; but in this species 
the dorsal fin, consisting of 8 rays, is opposite to the ventrals, in the 
latter it is in advance of them. 
Colours. Body dotted with rows of black spots; a black ocellus at 
the upper margin of the base of the caudal fin; six to eight rows of 
black spots along the dorsal fin, and about ten more bruoken-up lines 
of spots on the caudal, which is cut nearly square. 
The suborbital spine becomes minute in this species when adult.

Kyes situated in the middle of the length of the head, 2 diameters 
from end of snout, 13 diameter apart. 
Barbels long and thin. 
Scales distinct. 
Lateral line ceases opposite the end of the dorsal fin. 
Fins. Dorsal arises slightly in advance of the ventrals, and mid- 
way between the snout and the base of the caudal, which last is cut 
square, but some of the outer rays are rather shortened.
