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 j more highly vaulted on our specimen.

The species is unrepresented in the Dawson collection in the Peter Redpath Museum and specimens have not A^ic\ud1i0cpuesCDeawsonl been available for comparison, CaSoneiJrou' Grind" 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 and nas been compressed and distorted, produc- CapekTrou, Grind- *n§ ^ie effect °f a posteriorly placed beak and a stone L depression beneath it which it did not possess. Sanguinolites insectus Dawson? Cf. Sanguinolites insecta Dawson. Acadian Geology, p. 303, fig. 196, 1878. The specimen from Grindstone island dirTers 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 dirTers 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 Pleurotoma
