Canadian Spiders, II. 151 



Gongylidium canaliculatum. new sp. 



3 mm. long, pale brown like hrunneus and maximus, and resem- 

 bling these species. The eyes are low and the head a little ele- 

 vated behind them, more in the male than in the female. The 

 mandibles have a row of small teeth on each side of the claw, 

 but not the tooth on the front. The male palpi have the tibia 

 widened at the end with a half-round notch above, from which a 

 groove extends along the outer edge of the tarsus, ending in a 

 notch. Fig. 6. PL II. The tarsal hook is simple, slightly flat- 

 tened and curved in a quarter circle at the end. The epigynum 

 shows two round opaque spennathecae at the sides and nearer the 

 middle two dark ridges converging backward. Fig. 6a. PI. II.

Bathyphantes arborea. new sp. 



2.5 mm. long. Cephalothorax and legs pale yellow-brown, with- 

 out any markings. Abdomen light on the back with a black 

 middle stripe half its length and a black stripe on each side. The 

 markings of the hinder half are small, usually disconnected, and 

 sometimes absent. The light part of the abdomen is covered with 

 opaque lighter spots showing through the skin. Fig. 10. PI. II. 

 The under side of the abdomen is dark gray with a light area on 

 each side. The sternum is also dark gray, and the legs and max- 

 illae pale. The epigynum is of the usual kind, projecting but 

 little from the surface of the abdomen. Fig. 10b. PI. II. The 

 male palpi are small and compact, the tarsus and tarsal hook 

 resembling somewhat those of B. furcatus from the Sandwich 

 Mountains, N^ew Hampshire. Figs. 10c, lid. PI. II. 



Contrary to the habits of most of the genus, this spider lives 

 in the driest of places in spruce trees high above the ground, in 

 company with Linyphia phrygiana; Banff, Laggan, Yoho Valley 

 up to 7000 feet. 



Bathyphantes occidentalis. new sp. 



2.5 mm. long. Cephalothorax pale yellow with dark edges and 

 an indistinct dark square in the middle. The legs are pale with 

 dark rings at the ends of the joints and middle of the tibia, the 

 markings stronger in the female than the male. The abdomen has 

 a wide middle band made up of transverse spots connected by a
