PHOLCIDAE. 

 Hypsorinus,^ gen. nov. 



Eyes elevated on a tubercle. Anterior row of eyes strongly re- 

 curved; median eyes with radius one third more or less than that 

 of the laterals, near together and only about their radius from laterals. 

 Posterior row of eyes a little procurved, the space between medians 

 in type only one and a third times their long diameter. Area of 

 median eyes trapeziform, clearly longer than posterior width. 



Abdomen short, strongly elevated, and in type distinctly higher 

 than long. 



Legs in both sexes without spines. 



Chelicera in male with a short stout tooth near base of claw on 

 upper surface, (Plate 14, fig. 3). 



Tarsus of palpus much longer than thp tibia; pointed distad but 

 not abruptly more slender than tibia. 



Genotype. — Hypsorinus binghamae, sp. nov. 



This genus is most closely related to Smeringopus of Simon from 

 which it is here separated chiefly because of the following differences : — 

 the abdomen is high and subglobose instead of elongate and slenderly 

 cylindrical; the tarsus of the female palpus is much longer than the 

 tibia instead of abruptly much shorter and more slender; and the pos- 

 terior row of eyes is procurved instead of recurved, while the ante- 

 rior median eves are much closer to the laterals. 



Hypsorinus binghamae, sp. nov. 



Plate 13, figs. 1-9; Plate 14, figs 1-7. 



Carapace and sternum very light greyish brown, a darker median 

 longitudinal stripe narrowing up the clypeus over the eye-area and 



' vtf'os, top, 'opupcn, mountaineer.
