REPORT OP THE mRECTOR IQIO 173 



Dimensions. Length, 4 mm; height, 4 mm. 



Remarks. The slight truncation prevents the shell from being 

 circular as described by Hartt for his specimen from the base of the 

 Windsor limestone. In other respects it agrees 

 very closely with his description and the bit of sur- 

 face detail figured by him, unless the lamellae are 

 more highly vaulted on our specimen. The species 

 is unrepresented in the Dawson collection in the 

 Peter Redpath Museum and specimens have not ^^'cadiiFxiVhlZsoL 

 been available for comparison. *^^p/ le Trou. Orind-

Modiola pooli Dawson? 



Cf Modiola pooli Dawson. Acadian Geology, p. 301, fig. 100, 1878. 



These specimens, while larger, may be identical with M. pooli 



Dawson. The Shubenacadie specimens seem slender, 



but if they were increased to the size of these 



^ might be identical. The specimen figured is a cast 



Modiola pooli ^"^ ^^^ ^^^^ compressed and distorted, produc- 



Ca?eTeTrou, Grind- "^§ ^^^^ ^^^^^ ^^ ^ postcriorly placcd bcak and a

Sanguinolites insectus Dawson? 



Cf. Sanguinolites insecta Dawson. Acadian Geology, p. 303, 

 fig. 196, 1878. 



The specimen from Grindstone island differs from Dawson's 

 figure in not contracting quite so rapidly toward the beak. Since 

 the beak of Dawson's specimen and of ours are both missing it is 

 impossible to say whether or not they are specifically identical. 



Euomphalus exortivus Dawson? 



Cf. Euomphalus exortivus Dawson. Acadian Geology, p. 309, 

 fig. 118, 1878. 



Mold of specimen only, except a flattened section of outer whorl. 

 It is clearly related to the above species, but is much larger, being 

 nearly twice the size. 



It differs from E. sulcifer angulatus Girty, from the 

 Guadalupian in being larger and having the sulcus more nearly in 

 the center of the whorl. 



Gastropoda, 2 species, all minute, too poorly preserved to identify. 

 Gastropod, a large Pleurotomaria-like species, too poorly pre- 

 served for identification.
