VI. — Canadian Spiders. By J. H. Emeeton. (With four Plates.) 



The spiders of Canada, as far as can be judged from the present 

 collections, differ little from those of New England. Out of 61 

 species, from Labrador to Manitoba, 56 species live in New England ; 

 and out of 48 species from the Rocky Mountains, 27 have been 

 found in New England. The spiders examined are from the follow- 

 ing localities : 



The Rocky Mountains, near the Canadian Pacitic Railway, from 

 5000 ft., at Laggan, up to 8500 ft. on the neighboring mountains. 

 A large collection from Thomas E. Bean. 



Rocky Mountains, lat. 49° to 52°, from 3000 to 5000 ft., J. B. 

 Tyrrell, 1883.

 Tyrrell.

Among the spiders of Canada are several species that live but 

 little south of its boundary, and there only at high elevations. The 

 most conspicuous of these is Epeira carhonaria^ which lives on the 

 Alps in Europe, on the White Mountains in New Hampshire, and 

 on the Rocky Mountains, as far south as Colorado, in all cases above 

 the tree line. In Labrador the same species was found by Packard 

 near Square Island, where the mountains are 400 to 1000 ft. high 

 and bare at the top. 



Pardosa grmnlandica has been found as far north as Disco Island, 

 Greenland, and along the coast to the Gulf of St. Lawrence. It is 

 common on the White Mountains above the trees. In the Rocky
