 Broad form 



Cumberland

Gaspe 



Dimensions. Large examples of the species measure 28 mm in length, 

 27 mm in width. The small shells average about 16-18 mm in length and 

 in width. 



Localities. Everywhere in the coast exposures on the north shore of 

 Gaspe Bay. In the middle and upper layers of the formation. Absent 

 from Perce Rock. The species is present in the lower beds of the Gaspe 

 sandstone, but it is very rare.

This world-wide early Devonic species is very abundant in the Gaspe 

 sandstone where it covers entire surfaces of layers and is the most profuse 

 in individuals of all its species. It is much less abundant in the limestones. 

 In both it maintains the characteristics of the shell in New York, Cumber- 

 land and elsewhere, though there are at certain layers of the limestones 

 very large specimens attaining a size not elsewhere noted. Otherwise 

 dependable differences are not observable. 



It is needless to enlarge upon the distribution of this species further 

 than to note the early record of its presence in the Falkland Islands by 

 Morris & Sharpe under the name Atrypa pal mat a. Salter described 

 itasOrthis aymara from various localities in the Bolivian Andes and 

 Ulrich has cited a large number of additional occurrences. It occurs at 

 Matto Grosso, Brazil, and in the early Devonic of South Africa and the 

 Cape ; in the United States at Cumberland, Md., throughout the New 

 York Oriskany localities where fossiliferous, and in Union county, Illinois. 

 It also rises into the Onondaga fauna in Ontario (Decewville beds).
