28 MR. F. DAY ON THE FISHES OF COCHIN. — [Jan. 10, 
oblique ; lower jaw the longest. The superior maxillary bone ex- 
tends as far backwards as the anterior third of the orbit. Rather a 
strong prominent crest at the nape; the bony bridge between the 
orbits narrow, with a low crest running along its centre. Orbits very 
closely approximating at upper surface ; a well-developed projecting 
angle at their anterior and posterior margins; the anterior the 
strongest. A bony ring surrounds opening to nostril. No scales on 
head. 
Feeth. Conical, an external row in upper jaw the largest ; smaller, 
but conical ones in lower jaw. 
Fins. Origin of ventral in front of pectoral, of first dorsal over its 
first third; one-tenth of an inch between first and second dorsal. 
Spines weak. Caudal wedge-shaped. Ventrals united. 
Scales nearly quadrangular, elevated along their centre. 
Colours. Of a general light brown, with some irregularly disposed 
dusky bands on the sides and back ; a dark brown bar descends 
directly downwards from the eye; several irregular brown marks 
about operculum and head. The first dorsal has a deep black cres- 
centic mark, commencing between second and third spines, and con- 
tinued to the last ; above this a white curved band, bordered above 
with black. Second dorsal, anal, and caudal brownish, barred with 
several series of rows of a darker colour. 
This fish appears in large quantities in the Kurriavanoor River, 
north of the town of Cochin, when the bar is broken down, and the 
freshes from the Ghauts reach the sea. It is not captured there 
more than 2 or 3 inches in length; but perhaps they may be the 
young of a larger species.
