have been of the tertiary age, which probably can not be 

 verified. Other specimens of similar character are recorded 

 as having been found on Martha's Vineyard ; in Monmouth 

 County, New Jersey ; and in Accomac County, Virginia.

FOSSIL FISHES OF WYOMING. 



In the course of a critical examination by Professor Cope 

 of certain fossil fishes found on the Green River, in Wyoming, 

 he discovered specimens of a species of Osteoglossum of large 

 size, and previously undescribed. A specially interesting 

 feature connected with this discovery lies in the fact that 

 the genus is at present represented by living species in New 

 Zealand, Borneo, and Brazil; but it has not hitherto been 

 found in North America, nor is it any where known as a 

 fossil. Proc. Am. Phil. Soc. 



CEPHALASPIS IX AMERICA. 



Professor Dawson, of Montreal, has lately discovered in the 

 Siluro-Devonian beds on the north side of Gaspe Bay the first 

 known American species of the genus Cephalaspis, a kind of 

 fossil fish especially familiar to all readers of Hugh Miller's 

 works, as one of the forms which he was particularly suc- 

 cessful in procuring. It has been recently described by Mr. 

 E. R. Lankester, and called Cephalaspis dawsoni, after its dis- 

 coverer. 



MASTODON REMAINS. 



The last number of the American Journal of Science records 

 the discovery of a large part of the skeleton of a mastodon 

 near Illipolis, Illinois. One of the tusks proved to be nearly 

 ten feet in length, and twenty-nine inches in circumference 

 three feet from the lower end. All the bones we/e in a fair 

 state of preservation, and of a dark, spongy, and porous ap-. 

 pearance. It is probable that the specimens will be added 

 to the collections of fossils now being gathered together by 

 Professor Worthen for the state cabinet.
