Show 1873.] SURGEON F. D A Y O N INDIAN FISHES. 237 It is also remarkable that at the time I collected a new species of Rohtee with barbels, m y old friend, the Rev. H. Baker, of Cottayam in Travancore, should have also found a second species furnished with these appendages. Amongst a small collection of fishes received from Dr. Duka at Darjeeling is a second Silurus new to India. The species which I termed S. punctatus (Proc. Zool. Soc. 1868, p. 155), I have altered to S. wynaadensis, as Cantor's Silurus punctatus from China is said to belong to this genus. I have received from various friends several other local collections, some of a large size, but have not yet had time and opportunity to examine them. CARANX BIDII, sp. nov. D.8'|£. A.2|i. L.1.24. Length of head f, of caudal §, height of body | of the total length. Eyes, diameter f- of length of head, 1 diameter from end of snout, and 1| apart. The maxilla extends to below the anterior edge of the orbit. Teeth fine in the front of the lower jaw, none on vomer or palate. Lower jaw slightly the longer. Fins : dorsal spines weak, the third and fourth of equal lengths, and the longest in the fin; caudal forked; pectorals falciform, rather longer than the head, and reaching to above the third or fourth anal ray ; ventrals scarcely extending to above the two preanal spines; no detached dorsal or anal rays, none elongated. Scales on body, head, and chest. Lateral line nearly straight from the opercle to below the first third of the second dorsal, where it very gently descends downwards; its plates are badly developed. Colours silvery; a broad, burnished, golden stripe extends from above the eye to the upper edge of the tail. Lower two thirds of the dorsal fin yellow, its upper third dark ; outer third of anal white, the rest yellow. A large deep-black shoulder spot. Hab. Madras. I found it very common in the markets up to 10 inches in length. The first specimen I saw had been collected, however, by Dr. Bidie, after whom I have named the species. POMACENTRUS JERDONI, Sp. nOV.

Eyes, diameter \ of length of head, £ of a diameter from end of snout, 1 diameter apart. Preorbital entire ; preopercle finely serrated along its vertical margin, and with a few coarse teeth at its angle. Opercle with two spines, the upper having a few more at its base. Angle of opercle slightly serrated, as is also the contiguous portion of the subopercle. Infraorbital ring narrow, not covered by scales. Fins: dorsal spines increase in length posteriorly ; the soft dorsal and anal pointed ; caudal lobes, especially the upper, produced ; second anal spine the longest and strongest; ventral reaches the |
