Habitat. — Station 186, off Cape York, in 8 fathoms; coral mini. 



One of the two specimens from this locality agrees very fairly with the variety 

 figured by Eeeve (fig. 296). The other has the itpper or free valve white, with the 

 exception of a few dark spots to'W'ards the umbones. Some of the spines near the outer 

 margin are tinted with fleshy orange, and the lower valve hiis more of the colour. The 

 interior is white, with a rich orange-red border, within which is a narrow zone of a pale 

 olive-brownish tint, becoming darker towards and upon the hinge-teeth. The margin in 

 the other example is not nearly so viAad, and of a lilac colour, and, Uke that of the other 

 shell, is zoned within with olive-brown. The species has been recorded from the 

 Mauritius and the Philippine Islands.

Habitat. — Station 322, off the mouth of the Rio de la Plata, in 21 fathoms; sand 



and shells. 



The shells from this locality, which I associate with this West Indian species, are 

 usually pyriform, and rather compressed, the free valves being almost flat, and invariably
