Length of head 4| to 5, of caudal fin 5, height of body 5 in 

 the total length. Eyes without adipose lids, situated behind the 

 cleft of the mouth, diameter one third of the length of the head, 

 one diameter from the end of snout, and also apart. The greatest 

 width of the head equals half its length. Upper surface of the 

 head flat and rugose. Upper jaw elongated, and projecting con- 

 siderably beyond the lower. The median longitudinal groove on 

 the head reaches the base of the occipital process, which is narrow 

 and twp sevenths as wide afe its base as it is long. Barbels the 

 nasal rather longer than the head, the maxillary reach the base of 

 the anal fin, the mandibular as long as the head. Teeth the 

 whole under surface of the snout toothed, the premaxillaries 

 being entirely in advance of the lower jaw, in two minute 

 patches on the vomer, and of the same character on the palatines, 

 the latter not continuous with those on the vomer. Fins 

 dorsal spine as long as the head behind the angle of the mouth, 

 finely serrated posteriorly. Pectoral spine strong, rough ex- 

 ternally, and with about ten strong teeth internally ; it is as long 

 as the head excluding the snout. Ventral arising somewhat 

 behind the base of the dorsal fin ; caudal deeply forked. Colour 

 silvery, a black spot on the occiput, and a black blotch at the base 

 of the dorsal fin. 



Hal. The Irrawaddi and other large Burmese rivers. It does 

 not appear to attain a large size.

 Length of head 5 to 6, of caudal fin 5| to 6, height of body 5| 

 to 6 in the total length. Eyes lateral and very slightly on the 

 lower surface of the head ; each with a broad, circular, adipose lid, 

 diameter 3 to 3| in the length of head, f of a diameter from 

 end of snout, and 1 apart. The greatest width of the head is 

 rather above two thirds of its length. Jaws compressed, the 

 upper slightly the longer, the cleft reaches nearly or quite to 

 below the front edge of the eye ; the width of the gape equals 

 one third of the length of the head. The median longitudinal 

 groove on the head extends to the end of the occipital process,
