Show 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 ahout 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). B. iii. D. 2/8. P. 1/3. V. 9. A. 2/5. C. 20. L. 1. 33-34. L. tr. 4/3. Length of specimens from 2 to 5T 47y inches. 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. B.iii. D. 2/8. P.15. V. 10. A. 2/5. C. 20. L. 1. 36. L. tr. 5/4. Vert. g. Length of specimens from 2 to 4-^y inches. Length of head fa, of pectoral -fa, of base of dorsal ^, of base of anal fa, of caudal f of the total length. Height of head \, of body f-, of dorsal fa, of anal g of the total length. Eyes nearer to the posterior than they are to the anterior extremity 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 abdominal profile is not so convex as that of the back. Sides moderately 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 mouth 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- |
