Description of a new species of Ostrea, found living in the waters of the coast 

 of South- Carolina. By Francis S. Holmes. 



OSTREA TRIANGULARIS. 

 Shell sub-triangular, sub-equivalve, sub-equilateral, thick, laminated; 

 beaks produced, acutely pointed, angular and slightly curved towards each 

 other; margins rounded; cavity of the shell circular ; muscular impression 

 very large, in proportion to the size of the shell, and placed near the margin 

 of the base. 



This Ostrea resembles the O. Edulis of the European coast, but is more 

 regular in form. Its triangnlar shape, large muscular impression and point- 

 ed beaks, readily distinguishes it from that species. 



A single specimen was found by the late Rev. Thomas J. Young near the 

 mouth of the Edisto River, and by him considered a new species and present- 

 ed to me. Lately, I obtained another specimen of the same animal from 

 Wadmalaw Sound, an arm of the Edisto River. I am not aware of its having 

 been found on any other part of the coast of South-Carolina.
