Several large Tunnies sent by Mr. Jayakar belong to this species, being undistinguishable from Atlantic specimens. In my first report I recorded the true Tunny, T. thynnus, from Muscat. And if I am right in not separating the Pacific T. macropterus from the Albacore, it must be admitted that both the true Tunny and the Albacore roam over the Atlantic, Indian, and Pacific Oceans. In the Indian Ocean T. thynnus must be by far the rarer of the two species, since it was not on record until discovered at Muscat by Mr. Jayakar. CARANGIDJE. 7. CARANX ROTTLERI, Bl. 8. CARANX LIOGLOSSUS, Gthr. A specimen 29 inches long. It differs from the much smaller specimens described by Bleeker as Lioglossus carangoides in the total absence of teeth, the still greater projection of the lower jaw, and the very small extent of the scaleless portion of the breast. The differences are, however, ascribable to age ; and I have not the slightest hesitation in referring this large example to the species described by Bleeker, of which a type specimen is now in the British Museum. 9. LACTARIUS DELICATULUS, C. & V. PHYSOSTOMT. CYPRINID^E. 10. DISCOGNATHUS LAMTA, Ham. Buch. This well-known Indian freshwater fish has been previously recorded from Aden, in Arabia. It is also found in Abvssinia. MUR^ENIDJE. n. MURJENA AFRA, Bl. CHONDROPTERYGII. CARCHARIIDJE. 12. CARCHARIAS ACUTUS, Riipp. 13. CARCHARIAS ELLIOTI, Day. This Shark is very closely allied to G. murrayi, Gthr.; but differs |
