SHELLS OF ORMOND MOUND. 169 



one is a land shell. As already noted, fully ninety 



per cent, of the shells are of the little triangular 



marine bivalve, Donax variabilis Say. This is at 



present a very common shell along the 



Atlantic coast from Cape Hatteras to 



St. Thomas. At low tide it may be 



gathered by the bushel from the sand Fi g . ^ 



along the beach opposite Ormond. It 



is still much used in making soup, and probably fur- 



nished most of the animal food of the people who 



formed the mound. 



The following is a list of the shells taken from the 

 mound :* 



UNIVALVES. 



1. Murex fulvescens Sowerby. One specimen 



from near the bottom of the mound. Frag- 

 ments of others were seen. It is a post-plio- 

 cene species which is yet somewhat rarely 

 found along the coasts of Florida and the 

 West Indies. 



2. Fasciolaria gigantea Kiener. Among a collec- 



tion of shells taken from the mound by Pro- 

 fessor Hitchcock and sent to me was a single 

 specimen of this large univalve. It occurs 

 quite commonly along the Florida coast.

 son, of the I . S. National Museum, and to Mr. L. E. Daniels, of Laporte
