300 MR. F. DAY ON INDIAN FISHES. [Mar. 14, 



Eyes. Diameter f of length of head, li diameter apart, 1 dia- 

 meter from end of snout. 



Profile from snout to anterior margin of dorsal fin almost straight, 

 then sinking along its hase it again becomes straight. Abdominal 

 profile more convex. Body compressed. 



Cleft of mouth short, oblique, not extending halfway to the orbit ; 

 the anterior surface of the lower jaw, when the mouth is closed, 

 forms part of the upper profile. Snout rather depressed. Lower 

 lip rather fleshj^, not covering the tip of the lower jaw. The supe- 

 rior pair of cirri reach as far as the middle of the orbit ; the inferior 

 pair extend from the angle of the mouth to beyond the base of the 

 ventral fin. Prgeorbital triangular, apex below. 



Flits. Dorsal short, placed opposite the anal, and commencing 

 midway between the anterior margin of the orbit and posterior 

 extremity of the caudal fin. Pectoral large, falcated, reaching to 

 the commencement of the ventral, which is short. Caudal deeply 

 lunated. 



Teeth. Pharyngeal teeth slightly crooked and pointed, bla, in a 

 single row. 



Scales of moderate size. 



Lateral line absent. 



Colours. Greyish silvery above, becoming silvery white below the 

 middle of the body, along which runs a silvery stripe, which has a 

 narrow yellow edge superiorly. In one specimen the silver stripe 

 was edged superiorly by a broad black band. 



Hab. Trichoor in Malabar. 



Subgenus Nuria. 



Differs from Esomiis in the presence of a lateral line strongly 

 curved. 



EsoMus (Nuria) maderaspatensis, sp. nov. 



B.iii. D. 2/7. P. 12. V. 9. A. 3/5. L. 1. 32. L. tr. 5/2. 



Length of specimens up to 3 inches. 



Length of head -fj, of pectoral |, of caudal ^ of the total length. 

 Height of head \, of body |, of dorsal \, of anal j- of the total 

 length. 



Eyes. Diameter f of length of head, 1 diameter apart, | of a dia- 

 meter from end of snout. 



Cleft of mouth short, oblique, not extending above one-third of 

 the distance to below the orbit, and gape three times as wide as the 

 cleft is deep. Two pairs of cirri, as in the last species. 



Fins. Dorsal short, its anterior half in advance of the origin of 

 the anal. Pectoral does not extend so far as the ventral ; neither 

 does the latter reach the anal. Caudal deeply lunated. 



Teeth. Pharyngeal teeth in one row, straight and sharp, 5/5. 



Colours. Silvery white, with a silvery line extending along the 

 centre of either side. Fins diaphanous. 



JJab, Bowany River. It is also exceedingly common at Madras.
