 By Joseph Sabine, Esq. F R.S. $c. 



Head January 15, 1822. 



In a collection of Natural History, received in England at the 

 end of the year 1820 from Captain John Franklin, oftke Royal 

 Navy, the Commander of the Kxpedition sent over land to ascer- 

 tain the position of the mouth of the Copper Mine Kiver, and 

 to explore and examine the Northern Coasts of the American 

 Continent, were specimens of three new species of the genus 

 Arctovnjs or Marmot. 



The whole collection had been made by Dr. John Richardson 

 and Lieutenant Robert flood (who accompanied the Expedition), 

 partly in the neighbourhood of Cumberland House, where the 

 party passed the winter of 1819-20, having left York Fort on 

 Hudson's Bay in the preceding autumn, and partly in an excur- 

 sion made to Carlton House in the succeeding month of May. 

 Cumberland House is a principal station in the interior of the 

 country belonging to the Hudson's Bay Company, about 450 

 miles in a direct line south-west of York Fort ; arid Carlton 

 House, also a station of the Company, lies nearly south of the 

 former, being about 150 miles distant from it. Soon after the 

 collection was received, it was placed in my hands by the direc- 

 tion of the Right Honourable the Earl Bathurst, the Secretary 

 of State, with a request that I would prepare a scientific descrip- 

 tion
