Show 1869.] SURGEON F. D A Y O N INDIAN FISHES. 513 In Madras, during the last two years, I have obtained several of the young S. lanceolatus, aud on dissection discovered that cseco-pyloric appendages were invariably absent. I was in hopes of obtaining the adult form to dissect, but in this I have been disappointed. On the other hand, I have now had the opportunity of personally examinihg Mr. Blyth's specimens, and commence answering the before-mentioned criticism by objecting to the words after S. coides, II. B. (=S. serillus, C. V.). I admit, S. coides, H. B., and S. se-rillus, C. V., are identical ; but Mr. Blyth's specimens turn out to be the same as the one I have figured as S. horridus, which is certainly not S. serillus, C. & V. Some of the specimens in the Calcutta Museum are as follows ; the others offer no particulars calling for notice :- a. S. lanceolatus, 4 inches long, stuffed, presented by the Madras Museum. Coloration as shaded in Bloch & Russell's figures. b. A stand of three specimens, collected by Mr. Blyth to demon-strate his views, and marked in his own handwriting. In Mr. Blyth's deductions I most entirely concur, only objecting to his name S. coides, H. B. ; for the adult is identical with what I figured as <S. horridus, C. & V. c. 9| inches long, still showing the markings of the immature ; but the yellow portion is being broken up by bands. d. 18 inches long, the bands on the body have disappeared, and the black bands on the fins are broken up into black blotches. e. 22 inches long, the mature S. horridus, C. & V., exactly like pl. 1. fig. 2 in the ' Fishes of Malabar.' In the museum of the Medical College in Calcutta, I had au opportunity of examining another fine collection of stuffed fish, mostly brought together by the late Dr. Walker. Amongst them is a beautiful specimen of the adult S. horridus, C. & V., 34 inches in length. I have not deemed it necessary to advert to the specimens Captain Mitchell sent to the British Museum ; the number of cseco-pyloric appendages in the S. serillus, C. <% V., and S. bontor, C. & V., at once show they cannot be the adult $. lanceolatus, Bloch. Probably Captain Mitchell only gave his opinion after reading Mr. Blyth's paper, which is incorrect, as the species he terms S. coides, H. B., is the one which I have figured as S. horridus, and amongst Hamilton Buchanan's M S . drawings I find an unfinished sketch of his $ coides, which at once shows it to be the same as iS. serillus, C. & V. Thus a personal inspection of the specimens in the Calcutta AIu-seum has distinctly proved that the species I figured as the adult 5. lanceolatus, Bloch, is identical with what Mr. Blyth considered to be the mature one. It therefore appears the more likely to be a correct conclusion, having been come to by two different persons in distant places, who were ignorant of each other's investigations, which were made from two distinct series of specimens. Only one thing appears to be now requisite, namely, to examine whether the S. horridus, C. & V., has or has not ca**co-pyloric appendages, as at present |
