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



spine was present, in the other it was absent. In dissecting seven 

 of these, four males and three females, the spine was present in the 

 former, absent in the latter. I am the more disposed to consider 

 this a sexual peculiarity, from having obtained a second Loach, in 

 which the same sexual difference exists. In this latter species, which 

 I shall describe at a future date, out of about forty specimens, I only 

 found the adult males thus armed. 



In these fresh specimens of the Platacanthus agrensis all have 

 about fifteen marks or blotches along the lateral line, with rows of 

 irregular longitudinal pencillings above it, and a superior row of 

 blotches crossing the back. Caudal more emarginate than lobed, 

 with three or four bars upon it, and a jet-black spot at its base having 

 a light ring around it. A number of small black spots on the side 

 beneath the pectoral fin. 



Garra gotyla (Gray).

At least twenty or thirty were captured at each haul of a small 

 drag-net, in a stream at the foot of the Neilgherries. On July 20th 

 one large female was found full of ova ; but this was not the rule, the 

 breeding-season being apparently completed. There were many 

 young ones, and the transverse fissure was apparent across the snout, 

 even in the smallest specimens. 



Hab. Common in the Bowany and most of the streams around 

 the base of the hills, but rarer in the Seegoor River. 



Garra jerdoni, sp. nov.

Length of specimens from 2 to A^-^ inches. 



Length of head ^, of pectoral -f^, of base of dorsal i, of base of 

 anal y\-, of caudal f of the total length. Height of head i, of 

 body %, of dorsal -f^, of anal g of the total length. 



Eves nearer to the posterior than they are to the anterior extre- 

 mity of the head ; diameter \ of length of head, 2 diameters from 

 end of snout, 2| diameters apart. 



The profile ascends in an almost regular curve from above the 

 snout, which is thick and prominent, to the anterior extremity of the 

 dorsal fin, whence it sinks to the base of the caudal. The abdo- 

 minal profile is not so convex as that of the back. Sides mode- 

 rately compressed. 



Mouth below. Snout broad, becoming rather pointed anteriorly 

 (not rounded as in the Garra malabarica, P. Z. S. 1865, p. 297), 

 and covered with mucus-pores, which remain persistent in the 

 adult. The gape of the month equals the length of the base of the 

 anal fin. The two lips are united and moderately thick. Behind 

 the lower lip is a round suctorial disk, the diameter of which is one-
