ACCOUNT- OF SOME NEW OR LITTLE-KNOWN SPECIES 

 OF FOSSILS, MOSTLY FROM PALEOZOIC ROCKS 

 OF NEW YORK 



The assembling and arranging of material for exhibition in the 

 new State Museum has brought together a number of specimens 

 which represent species either new to science or to the State, or 

 which exhibit features hitherto not observed. It has been thought 

 an opportune occasion to publish these together, although they are 

 derived from very diverse groups and horizons. The quantity of 

 the new material is so great that we are in this report able to present 

 only a first instalment. For this we have mainly selected material 

 which exhibits structures that more precisely fix the taxonomic 

 position of the species; and further material, as the fossils of the 

 - Bertie waterlime other than eurypterids, because of its temporary 

 interest in the discussion of the habitat of the eurypterids. Much 

 new material of Ordovician cephalopods has been left out of con- 

 sideration because the author intends to describe this in a separate 

 paper. 



Dr P. E. Raymond was so kind as to describe for us a new 

 Ceraurus from the Chazy rocks which was sent to him at his 

 request. His note is appended to this paper.
