 (PI. I. figs. 1, 1«, \h.) 



I propose to describe this variety in detail, and later 

 briefly indicate the points of difference between it and the 

 foregoing species, G. jerdonia, Day.

The body is cylindrical, the ventral snrface rather broad, 

 compressed behind the vent. The dorsal profile in front of 

 the dorsal fin is distinctly convex and, behind it, gently 

 slopes towards the caudal fin. The ventral profile in front 

 of the ventral fin is equally convex. The height of the body 

 in front of the dorsal fin is contained slightly more than 

 3| times in the total length without the caudal fin, and the 

 depth of the caudal peduncle at its narrowest part is less 

 than 7| in the total length. The head is small compara- 

 tively, and its length is contained nearly 4^ times in the 

 total length, and the depth at the occiput is exactly 5§ times 

 in the total length. The upper profile of the head gently 

 slopes down to tip of snout. The eyes, placed in the middle 

 of the head, are small, whose diameter is three in the intei'- 

 orbital distance, which is broader than the length of snout. 

 The intei'orbital space is convex or slightly flat. The snout 

 is obtuse, very faintly grooved between the nostrils, covered 

 with open mucous pores, which are rather small. The 

 upper lip is large and fringed, the mental disk is sub- 

 triangular, the labial fold being nearly as wide as the 

 cartilaginous pad. Both folds are granular. The anterior 

 barbels equal the posterior ones, or are only slightly longer. 

 The chest nearly free from scales f. A very large obtuse 

 angle is formed by the ojDercular folds with the mental disk. 

 The length of the pectoral fin equals the distance between 

 its anterior root and tip of snout, which also equals the 

 longest dorsal fin-ray. The longest anal and ventral fin-rays 

 nearly equal. The caudal peduncle merges insensibly into 

 the root of the caudal fin, which is lobed. The upper lobe 

 nearly always longer than the ventral lobe. The colora- 

 tion is variable. Uniform reddish all over, with the lower 

 surface of snout and mental disk redder, or uniform olive- 

 green, somewhat clouded darker on the back. A dark 



* 4i shown in the protograph is incorrect.

 This condition is certainly different from the undescribed Manipur 

 form referred to hv Dr. Aunandale.
