Iravadia trochlearis A. (;d.* -Many, in excellent < ondition, 

 Evidently abundant throughout the Indian Ocean. We have many 

 specimens from Bombay, and have seen it from Ceylon, Karachi, and 

 Persian Gulf Japan, Hong Kong. 



Family CAPUUDyli. 



Amathina tricostata Gm.— Very perfect, though not large. Only 

 one example. I\ast Indies, Japan. 



Crucibulum (Dispotaea) extinctorium Lm. (=C. scutellatum 

 Gr. var.)— Three, fine. West Indies, Ceylon, West Coast of America 

 from Chili to Mazatlan. 



Crepidula (Crypta) scabies Rv. — Many specimens, in good 

 condition. Ceylon, Singapore, China Sea, Japan. 



Crepidula (Ergaea) walshi Herm. (=C. plana Ad. Rv. var).— 

 Many good and characteristic examples. Abundant also at Bombay. 

 Japan, Singapore, China, Ceylon. 



Calyptraea diaphana Rv. (z=zMitridaria eguestris L. var). — Many 

 examples. Tryon has " interpreted this species in accordance with 

 general usage, the Linntiean species being indeterminable," He gives 

 a long synonymic list of forms representing such variety in shape and 

 sculpture, that it is not surprising that they were described as distinct 

 species by the older school of conchologists. China Sea, l'hilii)pines, 

 Indian Ocean, Prince's Island, West Africa, West Indies, AVest Coast 

 of Central America, Galapagos Islands. 



Calyptraea fibulata Rv. (=.Mitnilaria equesiris L. var.) — Several 

 good examples. Philippines, AVest Indies. 



Family XENOPHORID^E. 



Xenophora Solaris L. — One beautiful example. Malacca, 



Singapore. 



Family LAMELLARIID/E. 



Lamellaria perspicua L.— Neither we nor Mr. Edgar Smith 

 can discover any means of differentiating the ^Madras form from that 

 found in English waters. 



Family NATICIDyE. 



Natica lineata Lm.*— Medium-sized specimens, of typical form. 

 Singapore, Philippines. 



Natica marochiensis Lm. (=yV: maroccana Chemn.)— The 

 many examples in this collection of a small cinereous shell, quite 

 plain, and concentrically wrinkled in a characteristic manner round 

 the sutures, we cannot exactly identify, but presume it is one of 

 the many forms of Lamarck's protean species. West Africa, West 

 Indies, Panama to Mazatlan, Society and Philippine Islands, Lifu, 



Australia,
