MELVILL AND STANDEN : TEREBRA IN THE PERSIAN GULF. 213 



A highly pob'shed little shell (13 mm.) when in fresh condition ; 

 longitudinal costul^ very lightly impressed with dark brown narrow 

 fasciae beneath the sutures, and often regularly spirally brown spotted 

 at the interstices between the ribs in the centre of each whorl. The 

 body-whorl is thrice banded. 



Dr. R. Brinsley Hinds described it originally as from Ceylon and 

 Malacca coast. It is probably of wide distribution. It belongs to 

 the section Abretia H. and A. Ad. (Gen. Rec. Moll., i., 225, 1853). 



27 — Terebra trailli Deshayes.

Hab. : Bombay. 



This has not been recorded either by Mr. Townsend or Mr. A. 

 Abercrombie, but we have received specimens from another source 

 from this locality. It is peculiar to the Indian region ; the first 

 examples are recorded from Vizagapatam. Reeve describes it as most 

 nearly allied to T. cuspidata Hinds, an elegant smooth lightly coloured 

 shell from Cape Coast Castle, West Africa. The two examples in 

 J.C.M.'s collection are 25 mm. long, elegantly attenuate, subulate, 

 very smooth, the riblets becoming slight longitudinal straight waves, 

 'crenuled,' as the author of the Conch. Icon, expresses it; pale straw 

 colour, once banded with pale indigo, base by the canal dark brown. 



28. — Terebra tricincta Smith.

Hab. : P.G.. Henjam Island, rare. Bushire. I., Karachi, once 

 dredged. Ratnagiri. 



A species of about 15 mm. length, very nearly akin to T. persica of 

 the same author. 



29. — Terebra tricolor Sowerby.

A fine example from this place, accidentally omitted from the record 

 in our first paper. Originally from the Friendly Islands, it is found 

 to be widely distributed, and pretty frequent in the Eastern Archi- 

 pelago, Flores, etc. (Siboga Expedition). We recorded it from Lifu, 

 but no specimen exists to confirm our record ; and it may have been 

 inadvertently mixed up with the similarly QoXov^xt^ pygmcza Hinds.
