Length of head 7|, height of body 12 in the total length. Eyes — diameter i of the 

 length of the head, half a diameter from the end of the snout, and 1 diameter apart. The 

 greatest width of the bead *■ 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 

 Archipelago and the Australian Seas.

Length of head 4^, of caudal fin h\, height of body 5 in the total length. Eyes — rather 

 small, high up and in the anterior half of the head. 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 

 uninteiTupted 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 markings. A large black 

 blotch on the lateral-line above the anal fin, another between the pectoral and first dorsal.

 teriorly. Mouth terminal : the upper jatv slightly the longer. Nostrils, the anterior one ivith 

 slightly tubular edges, posterior with a barbel before it. Barbels eight. Eyes small. Villiform 

 teeth in the jatvs, none on the palate. A short dorsal fin toith one spine and five rays :
