XXXI. — On the Species o/" Veneridte found in Japan. 

 By Arthur Adams, F.L.S. &c. 



My list of the Japanese species of the Venus tribe is a tolerably 

 long one ; but only a few unrecorded species were met with, 

 Reeve and Sowerby both being occupied Avith seeking out and 

 describing every member, however obscure, of this beautiful 

 family just on my arrival in England. Meretrix lusoria and 

 its varieties form a favourite article of diet among the poorer 

 classes of Japan ; they call it " Famaguri Hamongudi;" and 

 great heaps of the shells are often found near their houses. It 

 affords them also amusement. From the thousands of odd 

 valves they select numerous pairs wliich are both marked with 

 a similar pattern, and, sitting round in a circle on their mats, 

 one throws a number of shells down promiscuously ; and the 

 object of the simple game is to select pairs of similarly marked 

 valves quicker than any one else ! 



The habitat of CMone cardioides, in the British Museum 

 Catalogue by M. Deshayes, is " Mare Antillarum," and that 

 of C. histrionica " America centralis ;" but these may be 

 errors.
