Length of head 5 to 6J, of caudal 8i, height of body 5 to 6^ in the total length. JJ^/es— diameter 

 4 to 41 in the length of head, li diameters from the end of snout, and 2|- apart. The greatest width of the 

 head equals its length behind the middle of the eyes. The lower jaw slightly in advance of the upper : the 

 width of the gape of the mouth equals half the length of the head. Bwrbels — the maxillary ones reach the 

 hind edge of the eye or a little further; the mandibular ones fine and short. Tee^i'i— in two short transverse 

 patches rather distant from one another in the median line. Fms — the dorsal situated in the commencement 

 of the second-third of the length of the body. Pectoral fin as long as the head behind the angle of the mouth, 

 the spine feebly serrated (entire in Burma) and half as long as the head. Ventral with ten rays in India, nine 

 in Burma. Golowrs — silvery, with a badly marked shoulder-spot. 



I found in Burma a variety of this fish, G. nigrescens, it was clouded all over with fine dark spots, and 

 had black tips to the caudal lobes, and nine ventral rays. 



The only specimen I obtained in India was the one figured from the Jumna. There are several in the 

 Calcutta Museum from the Ganges. The species is not common. 



Habitat. — Jumna and Ganges rivers, alBO Burma. Ham. Buchanan observes that it is termed at Patna, 

 TdmbuUyd pdptd or Gallichrous resembling a betel leaf.

Length of head 5^ to 6, of caudal 6 to 7, height of body 5 to 6 in the total length. Eijes — diameter 3| 

 to 4 in the length of head, 1 to 1^ diameters from end of snout, and 2 to 2^ apart. The greatest width of the 

 head equals its length excluding the snout. Cleft of the mouth descends to opposite the upper third of the 

 eye : the width of the gape equals 1/2 to 4/9 of the length of the head. Barbels — the maxUlary pair reach to 

 opposite the eighth or tenth anal ray : the mandibular ones are nearly 1/2 the length of the head. Teeth — in a 

 very narrow oblong patch on either side of the vomer, and not continuous in the median line. Fins — the dorsal 

 1/2 as high as the body, narrow (especially in Madras specimens) and situated in the commencement of the 

 second third of the length of the fish excluding the snout. Ventrals equal \\ diameters of the eye. Anal not 

 united to the caudal, the latter deeply forked. Golowrs — silvery, a dark round shoulder-spot over the middle 

 of the pectoral spine, this mark is very indistinct in Madras specimens fig. 3, but exceedingly dark in those 

 from Burma. 



The only objection to uniting the Madras with the Assam and Burmese form is that the former has 

 P. 1/12-13, the latter P. 1/15. The shoulder spot is not so well marked, and the dorsal fin not so developed in 

 the Madras variety. 



This fish is closely allied to C. bi/mactdatus, but has a larger eye, a narrow band of palatine teeth, much 

 longer pectoral fins and maxillary barbels. 



The Burmese form G. vwtatus is more elongated. 



'Habitat. — ^Madras, Assam, and Burma. Pig. 2 is from an Assam specimen 10'6 inches in length : fig. 3 

 (life-size) is from a Madras specimen.

Length of head 5 to 6i, of caudal 7, height of body 6 in the total length. Eyes — opposite the angle of the 

 mouth, diameter 5| in the length of head, IJ diameters from the end of snout, and 3 apart. The greatest width 

 of the head equals its length excluding the snout. Lower jaw strongly prominent. Barbels — the maxillary 

 reach to above the commencement of the anal fin, the mandibular ones are short. Teeth— in an interrupted 

 band across ^he vomer. Fins — dorsal narrow. Pectoral rounded, as long as the head excluding the snout, its 

 spine strong, nearly 1/2 as long as the head, and rather strongly serrated internally. A notch between the end 

 of the anal and the base of the caudal, the last being deeply forked with the upper lobe the longer. Golowrs — 

 of a deep grayish-brown shot with purple, fin membranes densely spotted with black. 



Specimens captured to the South of Canara or in the Cochin district show the most anal rays, a moi'e 

 elongated body, and longer mandibular barbels. 



Habitat.— Malah&r coast of India up to 20 inches in length. The specimen figured (16^ inches in length) 

 was from Canara.
