(I.) Aden. — In an interesting article by Mr. Edgar A. 

 Smith {Proc. Zool. Soc, 1891), we find only five species con- 

 tained in our list, and these are all, as might be expected, 

 of very wide distribution in Eastern Tropical Seas ; indeed 

 one, Area lactea, we have already referred to as being a 

 European shell, extending throughout the East to Japan ; 

 and of the Tellinidcs only one, T. edentula, occurs at Aden.
