No. 4. J DAWSON — POST-PLIOCENE. 403 



Cyclopterus lumpiis, Linn. 



The lump sucker occurs in nodules at the same place. 



Gasterosteus. 



In nodules at the same place, found by Sheriff Dickson, It 

 closely resembles the two-spined stickleback of the Gulf St. 

 Lawrence, but is not sufficiently perfect for description. 



Vertebrae and other fra2:ments of fishes not determinable, 

 have been found at Riviere-du-Loup, and a bird's feather in a 

 nodule on the Ottawa. 



The Mammalia are represented in the marine Post-pliocene of 

 Canada by Plioca Grcenlandlca, Muller, found in the Leda clay 

 at Montreal, and Beluga Vermontana in the same situation, and 

 also in the Saxicava sand at Cornwall (Billings). The latter I 

 believe to be identical with the niodern Beluga of the Gulf St. 

 Lawrence. 



In the superficial gravels of Ontario, probably more recent 

 than the marine beds, remains of a fossil elephant, Eutlephas 

 Jacksonii, have been found, and have been described by Mr. 

 Billings (Can. Nat. vol. VIII). 



FOSSIL PLANTS. 



The only locality where fossil plants in any considerable num- 

 ber have been obtained, is at Green's Creek on the Ottawa, 

 where they owe their preservation to the nodules of calcareous 

 matter that have enclosed delicate specimens which otherwise 

 could not have been secured from the soft Leda clay in which 

 the nodules are enclosed. In addition to specimens collected by 

 myself, I have examined the collections made by the late Rev. 

 Mr. Bell of L'Original, those of the late Sheriff Dickson, and 

 those of the Geological Survey. The whole were described in 

 my paper in the Canadian Naturalist for February, 1866, and 

 since that time no new material of importance has come into my 

 hands. The species recognized are : 



Drosera rotundifolla^ Linn. 

 Acer spicatum, Lamx. 

 Potentllla Canadensis, Linn. 

 Gaylussacia resinosa, Jones. 

 Populus hahamifera, Linn.
