Dr. Raymond retired from the Survey in 1912 and was followed 

 by Dr. E. M. Kindle as Invertebrate Palaeontologist. Kindle, like 

 Raymond, is not purely a laboratory palaeontologist but has devoted 

 much time to field work and stratigraphie problems and has con- 

 tributed important investigations on the peculiarities of stratified 

 rocks and their manner of formation. He is responsible for the dis- 

 covery of a Portage fauna in the basin of the Mackenzie River and 

 for the addition of the Elm Point formation to the Devonian of Mani- 

 toba. Mr. E. J. Whittaker and Miss Alice Wilson of Dr. Kindle's 

 staff have also contributed valuable additions to palaeontological 

 literature. 



Canadian palaeontology has been advanced greatly during the 

 past twenty years by many of the authors whose work has been 

 referred to in reviewing the stratigraphie development. It will be 

 remembered that a more extended knowledge of fossils was emphasized 

 as a characteristic of the new school of stratigraphers. In many 

 cases new species have been described by the authors and even special 

 papers on palaeontological subjects issued, as illustrated by the several 

 contributions of Dr. F. H. McLearn. In this connection we must 

 again refer to the great volume of purely palaeontological achieve- 

 ment due to the labours of Dr. John M. Clarke in the east and of 

 Dr. C. D. Walcott on the Cambrian of the Rocky mountains. Refer- 

 ence must aljso be made to reports on special palaeontological problems 

 published by authors not members of the staff of the Geological 

 Survey : 



George H. Girty^ — Carboniferous Fossils from Yukon-Alaskan Boun- 

 dary. 

 Carboniferous Fossils from the Upper White River. 

 Dr. Ray S. Bassler^ — Bryozoan Fauna of the Rochester shale.
