PLATE VIII. 



Since reporting on two collections from Japan and the Loo - Choo 

 Islands, the writer has received from the same source several 

 additional species, seven of which appear to be nndescribed. In 

 addition, one species from Bonin has come to hand. The occurrence 

 in Japan of the genus Chloritis, to Avhich I refer two shells of an 

 nndescribed species, is of very great interest ; and I may mention 

 in this connection that, in looking over the Lewis Collection of 

 Japanese shells in the British Museum, I found it to contain two 

 unnamed specimens belonging to an allied species of this genus. 



Furthermore, the discovery of the genera Gancsclla, Macrochlamys, 

 and Amouldia in the Loo - Choo Islands appears to me to be 

 noteworthy. 



The following is an enumeration of the species : — 



JAPAN. 



1. Arnouldia phtllophila, Reinh. Two specimens. Kashima, 

 province Harima. Hitherto only recorded from Mososeki.
