Valves. — Rather large in proportion to the animal; the so called „triangulär area", 

 is large, quadrilateral ; the fang-like body is large and hollowed out, the whole surface 

 is sculptured, the sculpture consisting of a series of transverse equidistant lines, ribbed 

 on their convex surfaces. The „central portion" is very large, broader than long, with a 

 „strongiy" marked concave depression running from the apex to the point. On about 

 two-thirds of its cutting-surface the sculpture is the same as that on the „triangulär 

 area" ; on the remaining portion the sculpture is indistinct. The „auricle" is scarely 

 at all developed. The subumbonal blade is broad and curved. There is no accessory 

 plate. 



Extreme length of valve 3 / 4 inch., breadth 5 / 8 inch. 



Palettes. — The stalk is about 1 / t of an inch in length, and of the thickness of 

 a strong pin; it is thin and semitransparent, blunt, and of rather an irregulär outline. II 

 expands into a broad blade-like portion, which is 1 / i inch long, and from being of the 

 thickness of the stalk expands into a breadh of 1 / 4 inch. The upper surface is hollowed 

 out, and indistinctly divided into two portions; it is flat on the inner, and convex on the 

 outer portion; it is solid and of a dark-brown colour. 



Vaterland: Ostindien (Singapore).
