382 THE GEOLOGY OF BERMUDA. 
Cypraea . 
Trivia rotunda, Kien., 
Columbella mercatoria, Linn., 
Columbella cribraria, Lam., 
Olivella oryza, Lam., 
Nasa candei, d’Orb., var. antillarum. 
For the preparation of the above list I am indebted to Henry L. 
Osborn, A. B., formerly assistant in Natural History in Wesleyan Uni- 
versity. Besides the shells of mollusks, those of Balanus also occur. 
Fragments of coral admitting of specific identification appear to be 
rare, the fragile skeletons of the coral animals having generally been 
pretty thoroughly comminuted.
