 extraordinary shell. Singapore, Malacca. 



Cucullaea concamerata Chemn. — Two, very fine. Indian Ocean

 distinctive and full grown. The geographical distribution includes 

 Ceylon.

 Also from Malacca. 



Nuculana CUSpidata A. Gd. — Many beautiful examples, abso- 

 lutely identical with a solitary specimen, in the British Museum, with 

 no locality. Gould's types came from North America, and it is strange 

 to have it reported from Madras.

juvenile condition. Those in the British Museum are from the 



Philippines.
