19.— ASTARTE TRIQUETRA Conrad. 



1846. Proc. Ac. Nat. Sci. Philad., vol. iii., p. 24, pi. i., f. 6. 



" Very small, triangular, elevated, equilateral and symetrical, 

 ventricose, polished, white, sometimes brown or purple on the 

 disk in form of a broad ray." Length ^ inch. 



Locality. — Tampa Bay, Florida. 



From Conrad's diagnosis, quoted above, it appears that this 

 species approaches closely A. triangularis, but not having seen a 

 specimen I am unable to say whether or not it really belongs to 

 the genus.
