and seven in the anal fin j with scarcely any lateral line, and 

 with a diaphanous body. 



The Guganio (Gugani) is probably found in most of the rivers 

 and ponds of the Gangetic provinces, as I have seen it in both 

 the Brahmaputra and Yamuna, the extreme rivers of that ter- 

 ritory. It scarcely exceeds an inch and a half in length, and 

 has a considerable affinit\ r to the Mola, (Species 71.) The form 

 is compressed, deep, and more prominent below than above. It 

 is diaphanous, so that eleven ribs on each side may be seen 

 through the scales. The back is dotted : the head, eyes, the 

 membrane lining the visceral cavity, and the spine, are coloured 

 like silver. The fins are diaphanous, the fore part of the dorsal 

 being dotted. 



The head is oval, small, blunt, and dotted. The mouth fs 

 small. The jaws protrude in opening ; the upper is the longest. 

 The nostrils cannot be clearly distinguished, The eyes are far 

 forward on the sides of the head, and large. The membrane of 

 each sill-cover contains four ravs. 



Before the fin the bach slopes downward. The scales are large 

 in proportion, and adhere firmly. The lateral line, if any exists, 

 is very faint. The vent is behind the middle. 



The dorsal fin is near the middle : the first of its rays is short, 

 the second strong, undivided, and indented behind : the others 

 are branched. Each of the pectoral fins has about twelve rays ; 

 but the lower ones are so slender as to be scarcely visible. Each 

 of the ventral fins has nine rays, of which the first and last are 

 undivided. The first ray of the anal fin is short, and the last 

 divided to the root. The tail fin is divided into two lobes.
