of the Maclurites inaguus division, and, as has been shown above, this 

 fact leads to the conclusion that the basal sandstone itself cannot be 

 considered as indicating the first or JfebertcUa exfoliata division. 



To their division C, Upper Chazy, lirainerd and Seely assign the 

 upper 57 feet of the section, api)arently on lithological grounds, for 

 they note no fossils other than an undetermined species of Bucania. 

 These 57 feet are almost barren of fossils, but in the top foot of the 

 formation the writer has found the characteristic second division fos- 

 sils, thus excluding the possibility of finding any upper Chazy strata 

 in the section. 



I'he strata of the Chazy at Crown Point thus contain the fauna of 

 the second cr Maclurites inaguus division only. 



Region Nortli of the Canadian Line. 

 In the region directly north of Lake Champlain fossils have been 

 collected and identified by members of the Canadian Geological Sur- 

 vey. Lists of these, by Logan, Billings, Whiteaves, and Ami, have 

 been published at various times, from 1863 to the present, and from 

 these lists the writer has compiled those which follow. The arrangement 

 of the lists is according to localities, beginning with the one nearest 

 Lake Champlain and going northward.

 little east of the River Richelieu.
