Hah. Persian Gulf, ofFHenjam I.slaud. 



A very narrow aciculate species, quite distinct from tlie 

 Bombay C. sykesii, Mel v.*, with which, from tlie figure, it 

 migiit easily be confounded. That is a much broader shell in 

 ])roportion, and coarser in its substance and sculpture. 



Tliree examples only, the most perfect being selected for 

 the type.

Uab. Karachi, 190G. 



A small Sella, conspicuous for its ochraceous and grey 

 colouring alternating spirally on the whorls, tlie spiral keels 

 on either side of the sutures being livid, while that in the 

 centre is ochraceous. Upon the bady-whorl the two inner of 

 the four spirals are of that hue, the outer being livid. The 

 base is curtly flattened and deplanate, with the columellar 

 margin very callous. 



The only example of this distinct form is imperfect, and 

 the nuclear details are therefore wanting.

C. testa breviter fusiformi, nitida, parva, laevi, alba, vel stramineo- 

 zonata; anfractibus sex, apicali parvo, ca^teris gradatulis, ad
