 The following communication among others was read : — 



" On a Terrestrial Mollusc, a Chilognathous Myriapod, and 

 some new species of Reptiles, from the Coal-formation of Nova 

 Scotia." By J. W. Dawson, LL.D., F.G.S. &c. 



Oq revisiting the South Joggins in the past summer. Dr. Daw- 

 son had the opportunity of examining the interior of another erect 

 tree in the same bed which had afforded the fossil stump from 

 which the remains of Dendrerpeton Acadianum and other terres- 

 trial animals were obtained in 1851 by Sir C. Lyell and himself. 

 This second trunk was pointed out to him by Mr. Boggs, the 

 Superintendent of the Mine. It was about 15 inches in diameter, 

 and was much more richly stored with animal remains than that 

 previously met with. There were here numerous specimens of 

 the land-shell found in the tree previously discovered in this bed, 

 — several individuals of an articulated animal, probably a Myria- 

 pod, — portions of two skeletons of Dendrerpeton^ — and seven 

 small skeletons belonging to another Reptilian genus, and probably 

 to three species. 



The bottom of the trunk was floored with a thin layer of car. 

 bonized bark. On this was a bed of fragments of mineral char- 

 coal (having Sigillaroid cell-structure), an inch thick, with a few 

 Reptilian bones and a Sternbergia-ca&t. Above this, the trunk 

 was occupied, to a height of about 6 inches, with a hard black 

 laminated material, consisting of fine sand and carbonized vegeta- 

 ble matter, cemented by carbonate of lime. In this occurred 

 most of the animal remains, with coprolites, and with leaves of 

 Noeggerathia {Poacites'), CarpoUthes, and Calami fesj also many 

 small pieces of mineral charcoal showing the structures of Lepi- 

 dodendron, Stigmariay and the leaf-stalks of Ferns, The upper
