ton; Oregon; Sitka, Alaska; Europe. Emerton, '04, p. 404, and '84, 

 p. 305; Slosson, '98, p. 248; Banks, '95, pp. 417, 425. Marx. '96a, p. 

 394. It seems probable that the most southern localities of this species 

 are confined to some restricted habitat.

Coelotes sp. A specimen, too young for specific identification, was 

 taken in a rock clearing (I, 2) near the Light-house. It spins a pocket 

 just about large enough for its body beneath loose rocks. 



Cicurina arctiata Keys. Where the soil was very thin on the jack 

 pine ridge (I, 5) one specimen was taken under a stone and a female 

 was found with a white disk-like cocoon containing a large number of 

 young white spiders. A specimen belonging to this genus was found 

 along the trail through the balsam forest in leaf mold at Siskowit Bay 

 (V, 4), but it is too young for specific determination. It spins a small 

 pocket-like web beneath flat stones. Frequents the dead leaves of 

 forests (Emerton ) .
