Appendix. 167 



On arriving at Montreal the excursionists paused for a 

 moment in the Windsor Station, at the request of Dr. 

 Wesley Mills, to vote their thanks to the authorities of the 

 Canadian Pacific Railway for the excellent arrangements 

 which had been made for the convenience of the party, thus 

 bringing to a close a most delightful excursion. 



Appendix to Paper on Bivalve Shells of the 

 Coal Formation. 



Note on Genus Carbonicola, McCoy. [Anthracosia, King.) 

 This genus, which occurs abundantly in the Coal Forma- 

 tion of Great Britain, is represented, so far as known, in 

 Nova Scotia by only two small species, both from the 

 lower part of the Coal Formation, or possibly from the 

 Lower Carboniferous. One of these is C. angulata (Naia- 

 dites angulata, Acadian Geology, p. 204, fig. 46.) It is 

 from Parrsboro, from beds holding fossil plants and, so far 

 as known, no marine shells. The other, C. Bradorica 

 (Anthracosia Bradorica, Ac. GeoL, p. 314, fig. 133 b) is from 

 a shale supposed to be Lower Carboniferous, at Eaddeck, 

 Cape Breton. The affinities of these shells are at present 

 uncertain, but will probably be discussed by Dr. Wheelton 

 Hind in a forthcoming paper. Its associations would seem 

 to indicate that the habitat of some of the species was simi- 

 lar to that of the genus Anthracomya, which at Parrsboro 

 are found in neighboring beds. The figure of 0. Bradorica 

 is reproduced here to show the characteristic form.

The deepest bore-hole in the world is at Paruschowitz, 

 in Upper Silesia, Germany On May 17, 1893, a depth of 

 2,000 meters (6,552 feet) was attained, when drilling was 

 interrupted pending a series of thermo metrical observa-
