﻿200 GANGETic FISHES. Order V. 



with eight tendrils, all a little longer than the head ; with a 

 smooth brownish olive body ; with eight rays in the fin be- 

 hind the vent j and with seven in the foremost fin on the 

 back. 



The Mangois (Mmiggoi) I found in the tanks of Northern 

 Behar. It is from three to four inches in length, little com- 

 pressed before, but wedge-shaped toward the end of the tail. 

 It is every where of an uniform lurid brown colour, inclining 

 to olive. 



The head is small, blunt, fleshy, and smooth. Two tendrils 

 proceed from the nostrils, four from the corners of the mouth, 

 and two from the chin. The mouth extends straight from the 

 extremity of the nose, and is large. The under jaw is rather 

 the longest. The lips are fleshy. The only teeth consist of a 

 slight roughness on the edges of the jaws. The nostrils are 

 near the jaw. The eyes are minute, high, far forward, and 

 near each other. The gill-covers are smooth, their apertures 

 large, and their memhranes exposed to view, but so thick that 

 the number of rays cannot be readily determined ; there 

 seems, however, to be about eight in each. There is no slit 

 under the throat. 



There are no naked bony plates on the shoulder, nor are the 

 shoulder-bones visible. There are no lateral lines. The vent 

 is near the middle. 



The first ray of the foremost dorsal fin is a strong prickle, 

 smooth on the edges, and ending in a point like whalebone ; 

 the others are branched. The second fin is small and oblong. 

 Tlie pectoral fins are low, and shorter than the head, each con- 

 taining eight rays, of which the first is a strong prickle, termi- 

 nating in a substance like whalebone. The ventral fins are 

 smaller than the pectorals, each having six rays. The first 

 three rays of the fin behind the vent are undivided, and gradu-
