Bellerophon sp. 



Plate 17, figures 23, 24 



A single broad backed specimen of medium size but very poorly pre- 

 served indicates the presence of a species similar to B. led a Hall (Ham- 

 ilton) with the surface marked by fine revolving lines. It can not at present 

 be more closely determined. 



Locality. Portage road, Gaspe Basin. 



Aviculopecten sp. 



A single left valve indicates the presence here of a fairly large species 

 of the genus, which does not, however, lend itself to exact comparisons. 

 Locality. Portage road, Gaspe Basin. 



Actinopteria (Pterinea) fronsacia nov. 



Plate ig^ figure 6 



This is a species having the size and proportions of the common and 

 well known A. b o y d i ' of the Hamilton fauna of New York but somewhat 

 more erect and with a larger auricle. 

 Its surface is marked by quite regu- 

 larly alternating radii and these are 

 crossed by imbricating concentric 

 lines which are closely crowded 

 together and crenulated fore and 

 aft. In A. boydi the radial rib- 

 lets are of more uniform size and 

 as usually preserved in the shales 

 show only inconspicuous evidence 

 of the lamellose concentric lines 

 here present. More closely allied 

 in ornament and in form is the A. 

 e s c h w e g i i Clarke,"" from the 

 Lower Devonic Maecuru sandstone 

 of the Amazonas. 



Locality. Portage road, Gaspe. 



Specific name. Richard Denys 



de FrOnSaC, son of Nicholas Denys Actinopteria (Pterinea) fronsacia. 



and proprietor of the Miramichi 

 country, 1690.
