1892.] FISHES FROM MUSCAT. 135 



Sci^NIDiE. 



5. SCI^NA SINA, C. & V. 



ScOMBRID^. 



6. Thynnus albacora, Lowe. 

 Thynnus macropterus, Schleg. 



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. tkpnnus, 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, B1. 



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^. 



10. DiscoGNATHus LAMTA, Ham. Buch. 



This well-known Indian freshwater fish has been previously re- 

 corded from Aden, in Arabia. It is also found in Abyssinia. 



MUR^NID^.

CHONDROPTERYGII. 

 Cakchariid^. 



12. CaRCHARIAS ACUTUS, Rijpp.
