 mountains the middle of September, just before camp was broken; 

 but a considerable collection was obtained, nevertheless. Although 

 only a part of the phanerogams have been determined, it is found 

 that several species have been added to the known flora of New 

 Mexico. Chief among the additions was a family new to the State, 

 the Sparganiceae. Several of the plants apparently represent spe- 

 cies new to science, descriptions of which will be published later.

COLLECTING FOSSILS ON CHESAPEAKE BAY 

 During 19 14, several trips were made by Mr. William Palmer to 

 the Chesapeake Miocene on Chesapeake Bay and some very impor- 

 tant material was collected. Many years ago four very peculiar 

 caudal vertebrae were described by Prof. Cope as Cetophis hetero- 

 clitus and these have ever since remained unique. About a dozen 

 vertebrae of this animal were collected during the year by Mr. Palmer, 

 and while the material is insufficient to reconstruct a skeleton, it 

 surely indicates that a snake-like mammal of perhaps 10 feet in 

 length and unlike anything known to-day, inhabited the Miocene sea. 

 The skull is not known. 



Material representing Zeuglodont and Squalodont mammals was 

 also collected, indicating that representatives of those groups lived
