as long as wide. The longitudinal furrow on the head extends to 

 the base of the occipital process. Barbels the maxillary extend 

 to, or even beyond, the base of the caudal fin ; the nasal halfway 

 to the orbit; the outer mandibularto the base of the pectoral, and 

 the inner two-thirds of that distance. Teeth in an uninterrupted 

 semilunar band across the palate. Fins dorsal spine rather weak, 

 nearly or quite as long as the head (in the young occasionally 

 shorter), finely serrated posteriorly. Pectoral as long as the head 

 excluding the snout, and reaching four sevenths of the distance to 

 the ventral ; pectoral spine stronger -than dorsal but shorter, being 

 from one half to three fifths of the length of the head, it is rugose 

 or finely serrated externally and denticulated internally. The 

 adipose dorsal commences above the last third or end of the ven- 

 tral, and its base equals about that of the rayed fin or even a little 

 more, whilst the extent of the interspace between the two fins 

 equals half the length of that of the rayed dorsal fin. Ventral 

 does not reach the anal. Caudal with deeply pointed lobes, the 

 three outer rays in the upper lobe being produced. Air-bladder 

 large and pyrit'orm. Colour bluish leaden superiorly, becoming 

 white beneath ; fins yellowish, stained with dark externally in both 

 the dorsal and caudal. A black spot about equal to the diameter 

 of the eye on the posterior and inferior portion of the soft dorsal. 

 Hob. Throughout Sind and India to Burma. Said to attain 

 feet ; a specimen in Calcutta is 3 feet long.

Length of head 4|, of caudal fin 4|, height of body 7| to 8 in 

 the total length. Eyes diameter 7 to 8 in the length of head, 2 to 

 2 1 diameters from the end of snout, and 1 j to 2 apart. The greatest 

 width of the head equals one half to four ninths of its length ; 

 snout spatulate ; upper jaw rather the longer ; the width of the 

 gape equals one third of the length of the head, the cleft shallow. 

 Upper surface of the head granulated in ridges, its median longi- 

 tudinal groove reaches the base of the occipital process, which is 

 twice as long as wide at its base, between its posterior extremity 

 and the basal bone of the dorsal fin is a separate interneural shield 

 from four times as long as broad in the young, to twice as long 

 in the adult. Barbels the maxillary extend to the middle or just 

 beyond the hind margin of the dorsal fin, the nasal to opposite the 

 middle of the orbit, the external mandibular to the base of the 

 pectoral, whilst the internal are one third shorter. Teeth on the 

 palate in an uninterrupted cresceutic baud. Fins dorsal one
