whales are not infrequent on the lower marine terraces, and are re- 

 ported as occurring also on the higlier terraces, l»ub this I have not 

 verified by personal observation. They probably belong either to the 

 " Humpback " or to the " Finner " wliale, l)oth of which are occasion-

 to have been more numerous. I secured last summer (1891) a large 

 jaw-bone found in digging a cellar in the :;helly gravel of the lower 

 terrace at Metis. It is now in the Peter Redpath Museum.

in the Pleistocene of Olrinnell Land and North Greenland 



{Ann. and Mag. Nat. Hist., 1877 p. 230; Zoologist, 1877, 



pp. 485-440). It would appear that these shells are found 



at various elevations, from near the sea level to about
