PLEISTOCENE FOSSILS. 267 



hardt, and Icelus uncinatus of Kroyer and Gill. I feel convinced, 

 also, that it must be the Gottus gobio of Fabricius, though this is 

 usually identified with C. [Gymnacanthus] tricuspis of Reinhardt, a 

 very distinct species. Gottus uncinatus occurs in Greenland and in 

 deeper water as far south as New England, according to Jordan, who 

 creates for it a new genus {Artediellus).* 



The total length of the specimen without the caudal fin, which is 

 absent, is four inches, of which the head measures one inch. It belongs 

 to the collection of Mr. Stewart. The other and less perfect specimens, 

 which I refer to the same species, are in the Peter Redpath Museum. 



Gyelopterus lumpus. Linn. 



The lump sucker occurs in nodules at the same place. 

 Gasterosteus aculeatus? L. 



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 detailed description. 



Salmo solar? Linn. 



Fossil — A head apparently referable to this species in a nodule from 

 Goose River, north shore of River St, Lawrence. 



Vertebrae and other fragments of fishes not determinable have been 

 found at Riviere-du-Loup and other places. 



Glass Aves. 

 A few specimens of feathers have been preserved in nodules at 

 Green's Creek. They have apparently belonged to small wading birds. 



Class Mammalia. 

 PJioca {Pagophilus) Grcenlandka. Muller. 



A nearly complete skeleton of this species, found some years ago in 

 the Leda clay near Montreal, is now in the collection of the Geological 

 Survey of Canada at Ottawa, Detached bones, also found near 

 Montreal, are in the Peter Redpath Museum of McGill University. 



More than twenty years ago, Mr, Billings, then at Ottawa, obtained 

 a nodule with certain bones enclosed in it from the Pleistocene clays 

 of Green's Creek, on the Ottawa, which have afforded so many beautiful 

 specimens of the Capelin and other fishes, and also of marine shells of 

 northern and cold water types. Mr, Billings regarded the bones as 

 those of the limbs of "a small animal of aquatic habits," but, not being
