 the Author has not bestowivl uj)ou the present M'ork that small 

 amount of extra labour which would have rendered it comi>lete in 

 itself. As it stands, we have the Old-World Antelopes, but nothing 

 about the (Jirafles; the American rrong-horncd Antelo])e is not 

 mentioned (at least, it is not in the index), nor is the lloeky Moun- 

 tain (loat {J/(i/il()cen(S )iioiit(i»Ks); and the red-deer fjroup is dis- 

 cussed, with barely an allusion to the Wajiiti. This would have 

 been intellii;ible if an arbitrary line had been drawn at Old-World 

 species ; but such is not the case, for there is a special chapter 

 devoted to the deer of South America. The Elk and the lieindeer 

 are treated under the head of "Asiatic Deer," but nothin;:;: is said 

 about their American representatives beyond the incidental remarks 

 that the former is not specitically distinct from the moose, nor the 

 latter from the caribou. These and some other omissions diminish 

 the value of a verv readable and instructive work.

" Note on the Genus Xaiadites, as occurring in the Coal Forma- 

 tion of Nova Scotia." By Sir J. William Dawson, K.C.M.G., LL.D., 

 F.R.S., F.G.S. With an Appendix by Dr. Wheelton Hind, R.S., 

 F.R.C.S., F.G.S. 



The specimens referred to in tlie paper occur most abuiulaiitly in 

 calcareo-bituminous shales along the coast, at the South Joggins, and 

 were described by the Author in ' Acadian Geology,' in 1800. 

 A collection of them has been submitted to Dr. Wheelton Hind. In 

 Q. J. G. S. vol. xix. 3Ir. Salter referred the shells described as 

 JS'awdites to his new genera Anthracoptera and Antliracomya. In 

 correspondence with Mr. Salter, the Author held that the shells 

 were probably freshwater, and objected to the name Anthmcomija 

 as expressing an incorrect view of the affinity of the shells ; ho 

 also stated several reasons in support of his opinions. The 

 Author continued to use the name Saiadites, but does not object 

 to the division of the species into two genera, for one of which 

 Salter's name ^J/j^/i/Yfco^^/trrt should be retained. Additional reasons 

 are given for the freshwater origin of these shells, and the Author 

 expresses his gratification that their affinities have been so ably 

 illustrated by Dr. Hind. 



Dr. Wheeltou Hind believes that the ' genus ' Naiadites contains 

 three distinct genera, for one of which the name must be retained.
