298 MR. F. DAY ON THE FISHES OF COCHIN. __[Mar. 14, 
the caudal, and a little in advance of the ventrals; it is higher in 
front than behind; its base is without scales. Pectorals inserted 
subhorizontally. Anal short, situated entirely in posterior fourth 
of the body, its commencement being midway between posterior ex- 
tremity of the pectoral and the termination of the lower lobe of the 
caudal. Ventrals short. Caudal large, emarginate, but not deeply ; 
base scaly. 
Lateral line nearly straight from upper margin of operculum to 
centre of caudal, and nearer the back than it is to the abdominal 
surface. 
Colours. Back deep olive, fading to dirty white on the abdomen ; 
a wide leaden-blue stripe runs along either side of the lateral line, 
becoming of a shot green along the four central rays of the caudal. 
Fins yellowish. 
Not rare in the Kurriavanoor River.

L. tr. 4/3. Cirri 4. 
Length of specimens from 1 to 2,3; inches. 
Length of head 2, of pectoral fin 4, of base of dorsal ;2;, of base 
of anal 54, of caudal 2 of total length. Height of head 4, of body 4, 
of dorsal 4, of anal + of total length. Diameter of eye nearly 4 the 
length of head, eyes upwards of | diameter from end of snout, 14 apart. 
Profile rises to anterior margin of dorsal; thence to caudal it 
slightly descends. Abdomen flat below, and its profile not so con- 
vex as that of the back; sides compressed. 
Mouth directed forwards and slightly downwards ; upper jaw over- 
hanging lower. Upper half of mouth forming a half circle; when 
it is wide open, the whole orifice is nearly oval. Tip of lower jaw un- 
covered by the lip. Lips continuous from upper to lower jaw ; post- 
labial sulcus deep, simple ; lower lip with numerous fine pores, thick- 
ened below symphysis. Przeorbital bone rather triangular, base in 
front. Snout bulging, and continued laterally into a slight lobe ; 
both it and preeorbital covered by crenulations. Cirri four, two on 
snout, two on superior maxillaries, which are as long as orbit. Nos- 
trils nearer to orbit than to end of snout; anterior tubular, and se- 
parated by a membranous valve from the posterior, which is broad, 
oval, and patent. Some widely scattered pores exist over the whole 
of the upper surface of the head. 
Fins. Dorsal arises midway between snout and base of caudal, and 
is slightly in advance of the commencement of the ventral, which 
last is nearly horizontal. Anal arises midway between posterior ex- 
tremity of operculum and termination of the caudal, and is completely 
behind the whole of the dorsal. Caudal deeply lobed. Dorsal and 
anal fins with a row of scales at their bases. Pectoral reaches almost 
to the ventrals, the tip of which last nearly touches the anal. 
Seales large; lateral line slightly descends. Pharyngeal teeth 
sharp, pointed, and slightly curved at their extremities, placed in 
three closely approximating rows.
