MELVILL AND STANDEN : TEREBRA IN THE PERSIAN GULF. 205 



acteristic. The spiral noduled band below the sutures is well marked, 

 the body-whorl possessing a double row, the rest of the surface of the 

 shell being closely transversely Urate. 



2. — Terebra babylonia Lamk.

T. babylonia Kiener, Coq. Viv. Terebra, pi. xiv., fig. 35, 35a. 



T. babylonia Reeve, Conch. Icon., xii., pi. 11, fig. 43 a, b, i860. 



T. babylonia Sowerby, Thes. Conch., I., p. 169, pi. 43, f. 67. 



Hab. : P.O., Henjam Island, Muscat, 10 fathoms, sandy mud. Also 

 not infrequent on the shores of the Gulf of Oman. 



This elegant, attenuate species, with fulvous orange tinge, becom- 

 ing more prominent on the body-whorl, while over all a pinkish 

 coating tends to subdue the more glaring colours beneath, is, with its 

 near ally T. deshayesi Reeve, one of the most refined of the genus. 

 It is widely distributed throughout the Eastern Tropics.

Lnpages carulescens Smith, Ann. and Mag. N.H., xi., 1873, p. 263. 



Hab.: P.G., Gulf of Oman, Maskat (Muscat) 10 fathoms, sandy 

 mud. Jask beach at low tide ; extending to the Mekran coast, and 

 fairly general on the shores of Beluchistan. At Charbar a large and 

 handsome variety was obtained, 2*25 inches in length, well and 

 notably marked upon a grey ground, with warm brown distinct longi- 

 tudinal flames. Mr. Edgar Smith's definition of Iinpages is as follows: 

 'Shell subulate, whorls entire, moie or less longitudinally striate or 

 punctate, suture indistinctly separated, with a narrow callous band 

 above it.' This equals the Leiodomus of Gray, non Swainson.

Hab. : P.G., Henjam Island ; Charbar. I., Karachi. 



A small, rather insignificant species, considered a Myurella by its 



author, 16 mm. in length, longitudinally closely ribbed, smoothish, 



particularly as regards the base of the body-whorl. We have not seen 



specimens from this region, but understand that Mr. Smith confirmed
