1869.] SURGEON F. DAY ON INDIAN FISHES. 919 
Eyes elevated, diameter 17 of length of head, 1} diameter from 
end of snout, | diameter apart. 
Body subcylindrical and compressed. 
Snout rounded anteriorly. A short fringed tentacle over the pos- 
terior third of the orbit; a small, simple, nasal one. Snout with 
a lateral lobe, the two lips continuous, the lower forming a broad ad- 
hesive sucker behind the symphysis of the lower jaw, with a distinct 
posterior fold. The upper edge of the lower lip is coarsely fringed. 
Gill- -openings wide, extending on to the lower surface of the head. 
Teeth in a fine single row, implanted in the gums of both jaws. 
No canines. 
Fins. Dorsals divided by a notch, or continuous. The first dorsal 
commences a short distance behind the occiput ; its spines are free 
to a greater or less extent; in some specimens the second is the 
longest. ‘The soft dorsal mostly equals in height the posterior third 
of the first dorsal ; sometimes the second dorsal is higher than the 
first, but it does not appear to ever be higher than the body. Anal 
lower than the dorsal, all its rays free in their external half. Pee- 
toral arises close to the gill-opening, its lower seven rays are free at 
their extremities. Extremity of caudal rays undivided and free. 
Colours. Olive, banded with a darker shade, the bands and the 
ground-colour being about equal in width. Head spotted. All the 
fins with dark margins, except the anal, which is tipped with 
white. 
Many specimens, up to 3} inches in length, exist in the Calcutta 
Museum. All were received from the Andaman Islands.

Snout elongated, lower jaw the longest, lower margin of preopercle 
denticulated. Preorbital large, also denticulated. Opercle entire, 
ending in a soft pointed extremity. Intermaxillaries very protractile. 
The posterior extremity of the maxilla. extends two-thirds of the dis- 
tance to below the anterior margin of the orbit. 
Eyes. Diameter 2 of length of head, 13 diameter from end of 
snout. 
Head acute, depressed, dorsal profile nearly horizontal. 
Teeth in pointed tufts, or two incomplete rows on the margin of 
the intermaxillaries. 
Fins. Dorsal small, situated in the posterior portion of the back. 
Pectoral short. Anal extending almost to the caudal, from which it 
is separated by a slight notch. 
Scales ctenoid. Lateral line absent. 
An accessory cavity exists above and behind the gills. 
Colours. A white band passes from the eye to the centre of the 
caudal fin, a second from the pectoral along the side, and a third 
along the base of the anal fin. 
Three specimens (not in a good state) exist, given by Dr. J. C.
