Venus (Linn.). 



V. imbricata (Sowb.) 



This little shell abounds in the sandy shingle of the 

 shore. 



V. {Chione, Megerle) co)\ (Wood), also found at Karachi. 



V. „ pmgius (Hinds.). 



V. „ Layardi (Reeve) = Ratnagiri. 



V. „ radiata (Chem.) = Tapes marmorata 



(Lam.) 

 „ orientalis 

 (Reeve). 



C pingtiis and radiata are extremely common, and the 

 latter is very variable in shape, young specimens being of 

 the typical Tapes form, whilst the old ones become much 

 more gibbous. Both are much sought for edible purposes, 

 and perfect specimens of all growths can easil}' be obtained. 



V. (Anaitis, Romer) isabellina (Phil,), Rare. 

 Clementia (Gray). 



C. papyracea (Gray). 



A single valve, which we cannot think can be other than 

 this species, though it is smaller than the typical specimen. 

 Tapes (Megerle). 



T. {Pjillastra, Sowb.) Malabarica (Chem.). 



T. „ textrix (Chem.). 



T. „ Indica (Sowb.) 



These are all beautiful shells when perfect, and T. Mala- 

 barica and T. textrix, the latter especially, are common. 

 With textrix the general form is very smooth and shiny, but 

 old specimens are often irregularly concentrically striated 

 and lose the characteristic web markings. 



Venerupis (Lam.). 

 V. macropJiylla (Desh. 



N.B. — Petricola bipartita (Desh.) There are specimens 

 in the British Museum of this shell from Bombay, but we 

 have not been fortunate enouijh to find it ourselves.
