distally, ordinary bristles covering the proximal portion while the 

 metatarsi are not at all scopulate. The tarsi are not armed. Patel- 

 lae, tibiae, and metatarsi armed with stout black spines as usual. 



Spinnerets short, about one half the length of the abdomen on ven- 

 tral side, much less slender relatively than in keithi: each joint atten- 

 uated distad. Black in color. 



Female {not fully mature). Length, 13 mm. Length of cephalo- 

 thorax, 6.2, mm.; width, 5 mm.

Loca/i/?/.— Huadquina, 5,000 feet, July. (Type, M. C. Z. 148, one 

 young female). 



The female described above is apparently not fully grown; but the 

 differences it presents especially in eye sizes and relations added to 

 the differences in proportions of joints of legs, the presence of spinules 

 on the labium and especially the pronounced differences in form and 

 relative length of spinnerets render it impossible to regard it as identi- 

 cal with the preceding species which comes from the same locality. 



ULOBORIDAE. 



Orinomus,^ gen. nov. 



Posterior eyes small, subequal, the series strongly recurved, nar- 

 rower than the cephalothorax, the medians farther apart than from 

 the laterals. Anterior eyes in a procurved series; medians farther 

 from laterals than from each other. Area of median eyes much wider 

 than long and much narrower in front than behind. 



First leg much the longest, the others in order IV, II, III. Meta- 

 tarsus I clearly shorter than tibia + patella I. Calamistrum not 

 reaching distal end of metatarsus IV. . 



Cribellum narrow; entire. 



Abdomen subglobose; bigibous above, not produced or acuminate 

 behind; spinnerets not quite terminal. 



' opeii-o/ios, mountain ranging.
