Conularia planicostata Dawson 



Conularia planicostata Dawson. Acadian Geology, p. 307, 

 fig. 117, 1878. 



Cast of specimen agreeing in all essential characters with Daw- 

 son's species. 



Conularia sp. 



Fragment of another species, too poorly preserved to identify. 

 It is quite slender with about 18 or more ribs in 5 mm. Though 

 poorly preserved, the ribs appear to have been crenulated. Striae 

 coarser and more distant than C. micronema Meek, somewhat 

 like C. s a m p s o n i Miller, but less obtuse. Striae more distant 

 than in C. s u b u 1 a t a Hall. 



This species may be the variety "novascotica" mentioned 

 by Dawson as named by Hartt, but it is uncertain. It does not seem 

 to belong to any other American species. 



Orthoceras sp. 

 Cavity formerly occupied by specimen. 



Endolobus avonensis Dawson? 



Cf. Nautilus avonensis Dawson. Acadian Geology, p. 331, fig. 124, 

 1878. 



Endolobus avonensis Hyatt. Proc. Amer. Phil. Soc. 32 :536, pi. 8, 

 fig. 36-39, 1895. 



Represented by a poor cast, small and distorted. The septa and 



siphuncle not shown. The dorsoventral diameter of the outer whorl 

 seems relatively large for the Windsor species. 



Endolobus? sp. 



Several small specimens in concretions which do not admit of 

 specific identification ; only camarate portion preserved. Septa 

 extremely convex, suture apparently simple and siphuncle placed 

 very near the venter. 



Gastrioceras? sp. 



A large shell of which the cast of the living chamber is preserved 

 and some of the outline of what may have been the camarated por- 

 tion. From the characters shown little can be determined. It has 

 a section corresponding roughly to some of the very large angulate, 

 subnodose members of the genus. Umbilicus is very wide. Trans- 

 verse diameter 52 mm; about a half the whorl from the aperture 

 41 mm. Diameter of umbilicus 26 mm.
