 Formation about Ottawa, Ontario. (Canad. Kec. Sci., vol. ii, No. 

 5, pp. 301-300, 1887. Montreal.) 



Meutioiis two iustances of the occurrence of ScoUthus in Chazy beds, from 

 which it follows that the occurrence of ScoUfhiis remains does not neces- 

 sarily indicate the exisieuce of Potsdam rocks, but that the beds may pos- 

 sibly be newer aTid higher up in the series. 



The extras were distributed in December.

 Wyoming Valley Carboniferous Limestone Beds, By Charles A. 

 Ashburuer, geologist in charge of the Anthracite Survey, and corre- 

 sponding member of the Wyoming Historical and Geological Society ; 

 accompanied by a Description of the Fossils contained in the Beds, 

 by Angelo Heilprin, professor of iuA^ertebrate paleontology, Academy 

 of Natural Sciences, Philadel[)hia. (Proc. and Collections Wyom- 

 ing Hist, and Geol. Soc, vol. ii, pt. 2, pp. 251-277, 1880. Wilkes 

 Barre, Pennsylvania.) 



Descriptions of the species, with numerous illustrations in the text (pp. 2G5- 

 277). No new" species are described. The author considers the fossils un- 

 doubted evidence of the Carboniferous age of the formation, although some 

 people may have thought that they belonged to the Permian.

Has a note by Mr. Whiteaves on the graptolites, from which it appears that the 

 beds in question belong to the Silurian system, as recently restricted in the 

 publications of the survey. These beds are near Campbell's mill (pp.l.S^, 

 and 16/7). 

 Gives a list of fossils from Perth, determined by Mr. H. M. Ami, from an horizon 

 not higher than the Lower Helderberg nor lower than the Niagara.

Defends the importance of the discovery and describes the beds in which the 

 bones were found, and states that all his observations induce him to believe 

 in the contemporaneity of the man of Penon and of the mammotb in the 

 valley of Mexico.
