Crista divaricata Chemn.* — Many specimens. Mozambique 

 (Hanley), Red Sea, Philippines (Cuming). 



Crista gibbia Lm. — One of our examples is unusually obese and 

 large. Philippines, Red Sea. 



Crista pectinata L. — Many, in all stages of growth. Indian 

 Ocean, Philippines, Red Sea. 



Circe personata Dh. — A delicate example of this somewhat 

 common Indian species. 



Sunetta meroe L. (=S. picta Schum.). — Two ; a pretty species, 

 and extremely variable in colour. Philippines. 



Sunetta seminuda Rv. — One beautiful specimen, pale flesh 

 coloured, with epidermis. Moluccas (Cuming). 



Dosinia modesta Rv. — A few typical specimens. Spain (Paetel). 



Dosinia radiata Rv. (—Artemis amphidesmoides Rv.). — Three or 

 four, but only one exhibiting the characteristic rayed marking, so 

 conspicuous in the figure in Conch. Icon. (pi. vii., fig. 37). The 

 geographical distribution would appear to be wide, extending from the 

 mouth of the R. Gambia, W. Africa, eastwards. 



Dosinia salebrosa Romer. — A pure white shell, very delicately 

 concentrically ribbed. Specimens in British Museum from Ceylon. 



Chione graphica Lm. (= Cytherea petechialis Lm. var.). — Also 

 reported from Sumatra and Japan. 



Chione (Omphaloclathrum) gibbosula Dh. — A few examples, 

 in good condition. 



Chione (Omphaloclathrum) layardi Sow.* — Not, perhaps, 

 quite typical. Found all round the coasts of India, Persian Gulf, and 

 extending to the Andaman Islands. A very abundant Indian shell, 

 occurring in every collection we have received from that country. 



Chione (Omphaloclathrum) puerpera L. — Two ; very large 

 and fine, and well marked. Philippines. 



Chione (Omphaloclathrum) scabra Hani. — A minute, but 

 elegantly chased Chione, of which there are some dozen examples in 

 the collection. Philippines, New Holland. 



Anaitis calophylla Hani. — Two small butcharacteristic specimens. 



Tapes (Textrix) malabarica Chemn. — Typical. Moluccas. 



Tapes (Textrix) sulcosa Phil. — Remarkably fine, with the 

 purple rays, and grey spots very distinct. Australia. 



Tapes (Textrix) textrix Chemn.* — Some rather small speci- 

 mens of ordinary character.

 form. In the Romerian arrangement adopted in some museums this 

 species is known as Chione pinguis. Ceylon, Tranquebar.
