150 ON A SKELETON OF A WHALE IN THE 



bones in the living species. I have compared them with speci- 

 mens in the American Museum at New York, and, while some 

 differences certainly do appear, yet it seems to me that 011 the 

 whole it would not be wise to create a new species where there 

 is so close similarity. 



Nicholson and Lyddeker, Manual of Palaeontology, page 

 1307, say : " Remains of Narwhal, Monodon monoceros, are 

 found in the Norfolk Forest bed and the Pleistocene of 

 Alaska." 



At present, Mcnodon has been, though rarely, taken as far 

 south as England. ' Monodon and Delvhinapterus are closely 

 allied species, and Flower, Trans. Zoological Society, London, 

 1886, placed thess two genera in a group, Beluginece, which 

 includes no others. 



Notes on fossil cetacea of North America. 



It may add to the value of this article if a few notes on 

 other fossil cetaceans are included. This is the more 'true 

 because nearly all the specimens of this order that have been 

 found have occurred in Canada. One of the most perfect 

 skeletons is that described by Thompson from Vermont, and, 

 with the possible exception of a few isolated bones, this is the 

 only specimen that has been found in the United States. The 

 following is, so far as I can ascertain, a list of all the specimens 

 thus far discovered: 



I. 1849. A nearly complete skeleton; Charlotte, Ver- 

 mont; Professor Z. Thompson. State Museum, 

 Montpelier, Vermont. 



II. 1858. Several caudal vertebrae; Mile-end Quarries, 

 Montreal ; Sir W. Logan. Museum of the Geological 

 Survey, Ottawa. 

 III. 1864. A few bones ; Riviere du Loup, Ont. ; Sir J. 



W. Dawson. Peter Redpath Museum, Montreal. 

 IV. 1870. A nearly complete skeleton ; Cornwall, Ont. ; 

 Mr. E. Billings. Geological Survey Museum, Ottawa.
