 For tlie preparation of the above list I am indebted to Henry L, 

 Osborn, A. B., formerly assistant in Natural History in Wesleyan Uni- 

 versity. Besides tlie shells of moUusks, 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.
