MELVILL AND STANDEN : MARINE MOLLUSCA OF MADRAS. 33 



Sanguinolaria hendersoni n. sp. (PI. I., fig. 7). 



S. testa tenui, fere Icevi, subnitida, obscure concentrice inmqiialiter 

 striata ; valvis postice et antice paullulwn hiulcis ; margine postico 

 subtrapezoide, paullum producto ; antico prolongate, rotundato, ventrali 

 rectiusculo ; dorsali leniter utrinque declivi ; umbonibus Itzvibus, roseis, 

 tcetera superficie pallide rosea. Long. 23, lat. 35 mm. 



A beautiful addition to a circumscribed genus. To no known 

 species does it nearly assimilate, save in colour, coming perhaps 

 nearest to the West Indian S. sangui?iolenta Gm., which, however, 

 is far more produced and gaping posteriorly. The type, from Mr. 

 Henderson's collection, is of the dimensions given above, but three 

 other specimens, smaller but quite perfect (long. 20, lat. 32 mm.) 

 exist in J. C. MelvilPs collection, which were obtained at a sale at 

 Stevens' auction rooms, in Dec, 1866, without label of locality. We 

 have much pleasure in naming this species after its discoverer.
