Da Costa described this shell from a specimen in the collection of 

 the late Dr. Fothergill. It is from the Western coast. 



The shell figured by Pennant, No. 48. A. PI. 48, as a Worn 

 shell of Venus Erycina, is probably of this species ; for it seems en- 

 tirely destitute of the longitudinal undulations that decussate the 

 transverse ridges in Venus Erycina.
