Length of head 6 to 6, of caudal fin 9 to 12, height of body 9 

 to 12 in the total length. Eyes small, situated above and behind 

 the angle of the mouth and in the anterior half of the head ; the 

 width of the interorbital space rather exceeds half the length of the 

 head. Upper jaw slightly the longer. Barbels four, the maxil- 

 lary reach the base of the ventral, the single mandibular pair as 

 long as the head. A single row of six widely separated open 

 glands under the mandible. Teeth in a single uninterrupted 

 horseshoe-shaped band on the vomer. Fins the pectoral as long 

 as the head behind the eyes, rounded, its spine moderately strong, 

 short, entire, and having a soft termination ; dorsal fin rudimentary, 

 and in the anterior third of the total length excluding the caudal 

 fin ; anal and caudal scarcely united. Colour uniform, purplish

Hob. The Himalayas ; Griffith is said to have sent this fish from 

 Afghanistan, but some Khasi hill specimens were unfortunately 

 mixed with his Afghan collections. I received several specimens 

 from Dr. Duka, who obtained them at Darjeeling, and Jerdon pre- 

 sented some to the British Museum, the largest of which is about 

 7'2 inches in length ; the locality was not stated, but the specimens 

 probably came from either the Kashmir or Assam regions.

 spine ; ventrals extend to the origin of the anal, which last is
