Il<il>. Clairniont Island, N.E. Australia (Cojijiini/cr). 



A fine specimen from the above locality is entirely white, with 

 the exception of the extreme tips of the beaks, which are of a pah' 

 rose tint, a feature apparently common in most white examples of 

 the species. The specimen in question is 37§ millim. in length, 

 the same in height, and 20 in diameter. In this species the dorsal 

 area is very distinct and smooth in the left valve, but sculptured 

 with the terminations of the concentric lamellae in the right. On 

 the contrary, the half of the lunule in the latter valve is generally 

 greater than the remainder of it in the left.
