Length of head 5i to 5|, height of body 3| to 4 in the total length. Byes — diameter 8| in the length of 

 head, nearly 3 diameters from the end of snout, and close together : the upper one-half in advance of the lower. 

 Head rather higher than long. The length of the snout equals about 1/3 of that of the head. The angle of 

 the mouth situated below the middle or last t^ird of the eye : the rostral hook covers the mandibular symphysis. 

 Two nostrils, a patent one between the orbits and a tubular one opposite the anterior-inferior angle of the lower 

 eye. Fins — right ventral absent. Dorsal and anal fin-rays low, the highest equalHng 1/4 of the height of the 

 body. Scales — ctenoid on both sides. Lateral-lines — two on the coloured side, separated by sixteen or seventeen 

 rows of scales : a single one on the blind side. Colours — on the left side reddish-brown with irregular vertical 

 bands which are continued on to the dorsal and anal fins. 



Habitat. — Prom Sijj-d through the seas of India to the Malay Archipelago and China. The one figured 

 was from Madras.
