26o The Ottawa Naturalist. [February 



maps can now be prepared and maps showing the distribution of 

 any species, whether of plant or animal. For this purpose it is 

 hoped that the Council of the Club will endeavour to secure from 

 the Department of the Geological Survey at least 200 black and 

 white prints or copies of the map of this district to be kept on sale 

 by our Club Librarian for the use ot the members of the Club. 

 They may, however, be purchased from the Geological Survey at 

 a nominal price. 



The report by Dr. Ells which is to accompany the map will 

 no doubt be hailed with great pleasure by all who will read it. I 

 should advise the members ot the Club to secure copies of this 

 report early if they do not wish to find the edition exhausted from 

 the demands that may be made upon it when issued. 



Catalogue of the Marine Invertebrata of Eastern Canada, by 

 Dr. Whiteaves, also of the Geological Survey, is a report which is 

 of special interest to the members of our Club, as it deals with the 

 marine invertebrates of the Lower St. Lavvrence, a goodly propor- 

 tion of which are to be found in the sands, clays and gravels of 

 our Pleistocene deposits in the Ottawa valley. Every year sees 

 new forms added to the lists of the Pleistocene fossils, and these 

 find their living representatives in the salt waters of the St. Law- 

 rence and adjoining basins of to-day. An excellent review of this 

 most important work of Dr. Whiteaves has already appeared in 

 The Ottawa Naturalist, p. 165 by Prof. E. E. Prince, and I 

 shall not trouble you with a notice of it from a geological stand- 

 point further than to state that the volume is most welcome and 

 timely and represents the work of a life-time, the accumulation of 

 vast amount of useful information all condensed for the use of 

 naturalists, fishermen and others interested both in the economic 

 as well as the scientific side of the subject. 



'■'■ Ancient Channels of the Ottawa River'"'' is the title ot another 

 paper by Dr. R. W. Ells, F.R-S.C. It appeared in the April 

 number of The Ottawa Naturalist, pp. 17-30 with map accom- 

 panying the same, and forms a contribution which ought to 

 stimulate the members of the Club to carry on the work there 

 delineated, with special reference to the immediate vicinity of the 

 Capital. The ancient or now abandoned river valleys are quite
