1901.] MOLLUSKS FROM THE PERSIAN GULF. 447 



Dredged iu company with Mangilia spursa and ohtasicostata, but 

 only in juvenile condition. The gradate whorls, straight ribs 

 (twelve in number on the body-whorl), and especially the smoky 

 black spiral dorsal band, most conspicuous just behind the outer 

 lip, amply characterize the species.

A most graceful white species, resembling a Mitra of the section 

 Gancilla. In addition to the description above given, we might 

 point out that on the fourth and fifth whorls the longitudinal ribs 

 are fewer and more incrassate than on the penultimate and body- 

 whorls ; the same with the spiral lirae. On the body-whorl these lii'se 

 are of varying thickness, the interstices are alveate. By some 

 malacologists this might be termed a Clatliurella, but the very 

 graceful form suggests greater affinity with the genus where we 

 have, at all events provisionally, located it. Our best thanks are due 

 to Mr. W. N. Sturt for the loan of the species, which, with many 

 other Mollusca of great interest, he has received direct from 

 Mr. Townsend.

 apicales duo subvitrei, delicatissime sub lente deciissati, eceteris ad 

 suturas multum impressis, ventricosis, arctissime longitudinaliter 

 costulatis, costis subobliquis, ad juncturas lirarum spiralium 

 multarum. gemmulato-tiitidis, anfractus ultimi costis ad sex et 

 viginti; apertura ovata, labro incrassato, albo, tiitido, sinu ad 

 suttiram lata, sed obscuro, canali paidlulum recurvo, brevi.
