tudinaliter oblique pluricostatis, transversivi regtilariter 

 I i rat is, apertura oblongd simplice, labro exterior e in medio 

 crassiusado, canaii brevissimd, inargine columellari obliqui- 

 planato. 



Long. 44 mill.

Hab. Bombay, up the coast {Abercronibie). 



A large, conspicuous species, of which all the specimens 

 before us are somewhat worn : not sufficiently so, however, as 

 to efface the sculpture. 



From P. Atkinsoni (Smith), crenularis (Ldim.), Jlavidula 

 (Lam.) it is quite distinct, being more allied to the smaller

Purpura (Stramonita) Blanfordi, sp. nov. 

 (PI. I. f 3). 



T. testa ovato-ftisiformi, crassa, cinereo-carned, anfractibus 

 qninqiie, longitudinaliter tubercnlato-cosiatis, undiqiie trans-

 conspicii^ unangulatis, idtiino anfractu bind serie tuberculato, 

 apertura ovatd, earned, labro extus biangulato, intus denti- 

 culato, margine columellari recto, simplice.

Hab. Bombay and Ratnagiri {A. Abercrombie, Herford, 

 and also W. T. Blanford in Brit. Mus.), Kurrachee (Brit. 

 Mus.). {Blanford). 



This species would appear common upon the rocks of 

 the West Coast of India. We have seen specimens from 

 Kurrachee, and believe the same shell occurs in Ceylon. 



The two specimens collected by Mr. Abercrombie, one 

 of which is figured, are the only ones I have seen quite
