J. H. Emerton — Canadian Spiders. 401 



Mountains it occurs at 5000 ft., at Laggan, and in Colorado at 8000 

 ft. It is also among the spiders from Lake of the Woods, and on 

 the Pacific coast it has been found at Portland, Oregon. 



JPardosa tachypoda lives in the Rocky Mts., White Mts., and 

 Labrador. 



Pardosa uncata, in the Rocky Mts. and Labrador. 



Pardosa glacialis lives from Disco I. to Labrador, and in the 

 Rocky Mts., and may be the same as P. hrimnea of the White Mts. 

 and New England. 



Lycosa fumosa is a new species from the Rocky Mts., near Lag- 

 gan, at 5900 ft. 



Gnaphosa hrumalis lives in the Rocky Mts., White Mts., and 

 Labrador. 



JEpeira patagiata is found at all the Canadian localities and south 

 as far as Massachusetts. 



Gnaphosa Gonspersa and Amaurohius silvestris live all over Can- 

 ada and New England, and farther south. 



Among the rarer species in these collections are two Epeiras of 

 the angulata group ; one, E. nigra, resembling the E. solitaria de- 

 scribed in ''New England Spiders ;" and the other, a small variety 

 of E. nordmanni. Lathy s pallida belongs to a genus new to the 

 northern part of North America. Ceratinella laticeps has a differ- 

 ent form of cephalothorax from the other species, it being widened 

 in front, separating the lateral eyes widely from the others. 



The absence and scarcity of several common species are noticeable. 

 Agalena nmvia is only found among the spiders from Lake Winne- 

 pegosis and one specimen from Bryon Island. 



Theridium tepidariorum is absent, though mentioned among Miss 

 Hunter's spiders from Montreal, described by Blackwall in 1871. 

 Epeira sclopetaria is also absent except from Ottawa, the common 

 species of this group being E. patagiata. 



The Attidse have been determined for me by Mr. Peckham and in- 

 clude one new species, Habrocestum montanum, from the Rocky 

 Mountains. Prof. Packard has sent me the spiders described by 

 Thorell from the Rocky Mountains and from the Polaris Arctic ex- 

 pedition, but I have not been able to find the spiders collected by 

 Packard in Labrador and described by Thorell. 



The earlier descriptions of Canadian spiders are hard to identify, 

 but most of them will no doubt be explained as the species become 

 better known or the type-specimens are found. . In 1846, Blackwall 

 described in the English Annals and Magazine of Nat. Hist, a col-
