the specimens were largely obtained in place, from the exposure 

 in the bluff, although on no occasion was a complete section seen 

 from base to summit. Of the material collected, the crustaceans 

 proved to be too fragmentary for determination, although Pro- 

 fessor R. P. Whitfield, to whom they were submitted for exami- 

 nation, expressed the opinion that they represented new species. 



About fifteen species of molluscs were separated out, from 

 which the following identifications were made: 



Pleria petrosa Conr. 



Nemoarca cretacea Conr. 



Cardium Bipleyanuvi Conr. 



Leiopista protexla (Conr.)? 



Inoceramus Sagensis Owen. 



Gryphsea vesicularis (Lam.). 



Scalaria Hercules Whitf. 



Pyri/usua sp.? 



All these species had been previously noted from or near to 

 the same locality and may be found included in Professor Whit- 

 field's works.* 



The plant remains number 26 species, of which 10 are ap- 

 parently new. Conifers are the most abundantly represented. 

 The branches of Cunninghamites, Sequoia and others, and 

 scales of Dammara make up about one-fourth of all the speci- 

 mens collected, and a section of one of the lignite masses 

 showed it also to belong to the same class. f 



This collection, meagre as it is, is nevertheless of interest as sup- 

 plementing our previous knowledge of the Cretaceous flora of east- 

 ern North America, beginning with the studies of Fontaine and 

 Ward, in the Potomac of Maryland; Heer in the Kome, Atane and 

 Patoot beds of Greenland ; Newberry, David White and the writer 

 in the Amboy clays of New 'Jersey, Staten Island, Long Island 

 and Martha's Yine_yard, and gives us at least an indication of 

 what mav be expected in case more extensive collections should 

 be made from the same horizon in the future. 



The main object in bringing the subject forward in its present 

 condition is not to present a finished contribution, but rather to 

 assist those who may wish to continue the investigation, to the 

 end that our knowledge of the horizon may be rendered more 

 complete.

t Sections prepared for microscopic examination were submitted to Dr. C. C. Curtis, 

 of Columbia University, who at once recognized their structure as coniferous. Dr. F. 

 H. Knowlton, of the V. S. Geological Survey, to whom they were subsequently sent, 

 determined them as belonging to the genus Pityoxylon. His description will appear 

 as an appendix to this paper.
