Length of head 7|-, height of body 12 in the total length. Fyes — diameter :!■ of the 
length of the head, half a diameter from the end of the snout, and 1 diameter apart. The 
greatest width of the head of its length. Snout rounded. The upper jaw the longer : 
the maxilla reaching to behind the posterior edge of the eye. Teeth — in the upper jaw in 
a rather widely-set, recurved row, and a canine-form one near the centre of the jaws : an 
outer row of small teeth. In two rows in the lower jaw the outer being the larger and 
somewhat curved, they are largest near the symphysis : 2 or 3 rows on the palatines : 
2 large ones, placed one before the other on the vomer, and surrounded by smaller teeth. 
Vent in front of a line from the base of the pectoral fin. Scales — absent. Fins — vertical 
ones enveloped in skin : the dorsal commencing the length of the head behind the front 
edge of the eyes : the anal beginning behind the vent. Pectoral as long as the head 
behind the eyes. Colours — ^yellowish-red, a silvery band going from the upper edge of the 
opercles along the first fourth of the body : opercles silvery : end of tail with some black 
reticulations. 
Habitat. — An example 4‘8 inches long received from Madras. It is found in the Malay

Length of head dj, of caudal fin 5i, height of body 5 in the total length. Fyes — rather 
small, high uj) and in the anterior half of the bead. The greatest width of the head 
equals two-thirds of its length. There is a moderate rise from the snout to the base of 
the dorsal fin. Upper jaw the longer, upper surface of head smooth. Barbels — a maxillary 
pair reaching to the posterior edge of the orbit, no others were detected. Teeth — in an 
uninterrupted villiform band across the palate. Fins — dorsal spine smooth and nearly as 
long as the fourth ray which is 4/5 as high as the body below it. Adipose dorsal rather 
long, commencing a short distance behind the base of the rayed fin. Pectoral spine 
denticulated internally. Caudal forked. Colours — yellowish horny with darker shades of 
olive brown on the snout and along the back, also some cloudy mai’kings. A large black 
blotch on the lateral-line above the anal fin, another between the pectoral and first dorsal.
