1865.] MR. F. DAY ON THE FISHES OF COCHIN. 13 
Inferior margin of interoperculum strongly denticulated : thus with 
the double denticulated edge of the przoperculum and the denticu- 
lations on the interoperculum there are three parallel lines of teeth- 
ing in this species. A sharp spine directed backwards at the poste- 
rior superior angle of the orbit; and two or three more along its 
posterior edge, but separated from the first by a notch. Ventral 
spine comparatively long, reaching close to the origin of the anal, 
whilst its soft rays extend as far as the third anal spine. 
Length of head one-third of the total ; height of body two-sevenths 
of total length ; second dorsal spine two-thirds the height of body ; 
second anal spine half the height of body.

All the Therapons are indiscriminately termed Keetcha, and, un- 
less by the poorest of the population, are utterly rejected as food, 
as they are reputed to prey on any corpses that may be floating in 
the backwater. They do not, in Cochin, attain to the size they are 
found in Madras.
