584 SURGEON F. DAY ON INDIAN FISHES. [Nov. 26, 



Lateral line in a single tube in each scale, but only distinctly ap- 

 parent in the anterior third of the body ; still a rudiment of it is per- 

 ceptible at irregular intervals as far as the centre of tbe base of the 

 caudal fin. A small row along the base of the dorsal fin. 



Colours. Light greenish superiorly, becoming white along the 

 abdomen. A brilliant broad silvery band extends from the eye along 

 the side to the root of the caudal fin. A small black spot is present 

 at the base of the dorsal fiu at its anterior margin, and a large black 

 finger-mark at the root of the tail. The coloration is essentially 

 that of an Ambassis. 



This elegant little fish does not seem to grow to any large size. 

 At Kurnool, in October, females 2 inches in length were found full 

 of ova. 



Hah. Kurnool, in Madras ; some specimens have also been re- 

 ceived from Arcot, showing that its geograi)hical range is wide. 



This fish cannot be looked upon as a typical Barhus, but approaches 

 that genus, as defined by Dr, Giiuther, more nearly than any other.

Length of specimens up to 5^^ inches. 



Length of head +, of pectoral 4, of base of dorsal \, of base of 

 anal -^, of caudal | of the total length. Height of head g, of 

 body \, of dorsal fin ^, of anal ^ of the total length. 



Eyes without any adipose lid ; diameter ^ of length of head, 1 dia- 

 meter from end of snout, 1 \ diameter apart. 



Mouth antero-inferior ; there is a slight thickening of the mucous 

 membrane covering the jaws, but not sufficient to be termed horny ; 

 in fact it would be scarcely apparent were it not that it is of a dark 

 colour ; if the species grows much larger, which is doubtful, it may 

 become horny. Lips thin, not fringed, no lateral lobe, no tubercle 

 on symphysis, nor pores on the snout. No barbels. 



Pharyngeal teeth crooked, sharp, 5, 4, 3/3, 4, 5. 



Fins. Dorsal arises slightly in advance of the ventral, but does not 

 extend so far as to above the commencement of the anal ; the upper 

 margin of the fin slightly concave, its third undivided ray articulated 

 aud weak. Caudal deeply forked. 



Scales. No enlarged ones along the base of the anal fin. 



Lateral line proceeds direct to the centre of the base of the caudal fin. 



Colours. Eeddish brown along the back, and silvery over the ab- 

 domen. A black band passes from the eye to tbe centre of the base 

 of the caudal fin. Fins whitish. A dark band along the middle 

 third of the dorsal, and a dark edging to the caudal. 



This very pretty little fish was collected for me, amongst others, 

 from the Fraserpett river, at the base of the Coorg Hills. Judging 

 from its coloration, it is a small species and only found in hilly 

 regions or along their bases. 



I have named it after Dr. Nash, to whom I am indebted for many 

 specimens from the Coorg district.
