The Ottawa Naturalist. [December 



II. Calciferous. 



I. Potsdam. 



From the above list it will be seen that the red shales and 

 marls of the Medina which occur to the east of Ottawa City, in 

 the County of Russell, :md which have been recently visited by the 

 writer, are not included, inasmuch as no fossil organic remains 

 have as yet been obtained from them. 



The specimens are all labelled and named. The labels indi- 

 cate the g-enera and species, together with the name of the author, 

 as is customary, the geological formation, the precise locality from 

 which they were obtained, besides the name of the collector and 

 the date when they were obtained. A type-written list of the 

 species included in this collection has been placed on the wall 

 alongside the case. Any additions that may be made to this col- 

 lection by members of the Club will be incorporated in this 

 nucleus of a collection of the fossil remains of Ottawa a>»d vicinity. 

 It is earnestly hoped that members of the Geological section and 

 others will contribute and co-operate in making the series as com- 

 plete as possible. I would venture to suggest that this collection 

 bear the name " Billings" collection of fossils," not only to do 

 honour to one of Ottawa's greatest men in the list of the departed 

 from this sphere of activity but in order to strive to associate 

 with it the name of a true lover of Nature, and especially of fossil 

 organic remains. 



Graptolites. — From 1879 to 1888, whilst engaged in studying 

 the fauna of the Utica about Ottawa, as leader in the Geological 

 branch of our Club, the writer obtained not a few specimens of 

 graptolites in the bituminous shales of this formation. Some of 

 these, especially the Lepiograptidcp a.nd a number of Climacograpti, 

 were in an excellent state of preservation and have since been for- 

 warded to Prof Chas. Lapworth, of Mason Science College, by 

 the authorities of the Geological Survey department at Ottawa, to 

 whom they had been presented by the writer. 



Prof. Lapworth has kindly undertaken to examine the same, 

 and his report is now in the hands of the department. We hope 

 to see the result of his examination of the species of Ottawa 

 Graptolites published at no distant date.
