Length of head 6f to 5|, of caudal 5^, height of body 5 to 5^ in the total length. Hyes — diameter 2/5 

 of length of head, 1/2 a diameter from end of snout, 2/3 of a diameter apart. Body elongated, strongly 

 compressed. Maxilla reaches to below the middle of the orbit. Fins — dorsal arises rather nearer the base of 

 the caudal than the snout, and rather behind the origin of the ventrals : the anal commences under the posterior 

 Extremity of the dorsal and has its last two rays detached : caudal forked in its posterior third, the lower lobe 

 the longer. Scales — 10 or 11 serrated scales along its abdominal edge, commencing below the pectoral fin : 

 anterior to the ventral fin there are 10 or 11, and 7 or 8 posterior to it. Colours — silvery, with a light band. 



Habitat. — Orissa and Bengal : rarely attaining above 2 inches in length. The example figured (life-size) 

 was from Orissa. 



Genus, 6 — Pellona, Gwoier and Yalenciermes. 



nisha. Gray : Platygaster, Swainson. 



Bramchiostegals six. Body rather elongated and strongly compressed., with the thoracic and abdominal edges 

 serrated. Mouth of moderate size, upper jaw generally emargimate and shorter than the lower. Fine sharp teeth in 

 the jaws, palatines, and pterygoid bones, also on the tongue, but none on the vomer. Dorsal fin small, median. 

 Ventrals small, inserted anterior to the dorsal : anal elongated. Scales large, or of moderate size, rarely small. 



Owing to the individual variations amongst examples of this genus they are difficult to distinguish : 

 besides which, the types of Cuvier and Valenciennes require to be thoroughly re-examined.
