Shell sand. St. Vincent Gulf; Fowler's Bay. Also New- 

 South Wales {Angas). 



Quadrately ovate, translucent, shining, anterior side short, 

 posterior extremity roundly truncate ; length, three-eighths of 

 an inch. Left valve with one conical tooth in front of the 

 cartilage pit, with a lamelliform tooth close to it ; there is a 

 rather distant lamelliform tooth on the posterior side. Right 

 valve with a laminar tooth in front of the cartilage notch, and 

 a similar one posteriorly, but more distant. 



This species resembles externally Mysetta anomala, with which 

 Angas confounded South Australian specimens of K. solida 

 sent to him by me for identification, under which name it 

 appears in the above-quoted paper.
