360 ARANEIDEA. 
Males and Females. 
a. Central posterior eyes without any horn-like spurs above. Carapace parallel- 
sided, twice as long as broad. Femur i. with a fringe of hairs on the inner 
side basally. Abdomen very long, without tubercles. . . . . + « + Jomgipes, sp. n. 
b. Central posterior eyes with a horn-like spur above. Carapace much broader 
just behind the cephalic area. Femur i. without any basal fringe of hair 
on the inner side. Abdomen () with two tubercles on each side before 
the middle; (§) with an additional pair of tubercles in front at the 
shoulders . 2. 1. 1 1 ew ee eee ee ee ee eee + Guritus, SP. D. 
1. Deinopis longipes, sp.n. (Tab. XXXIV. figg. 1, la-c, g; 2, 2a, b, 2.) 
Type 3, gynetype 2, in coll. Godman & Salvin. Total length, g 19, 9 25 millim. 
Hab. Mexico, Mexican Boundary, Rio Yxcam (mus. Godman & Salvin), Atoyac in 
Vera Cruz (H. H. Smith) ; Guatemata (Sarg); Panama, Bugaba (Champion). 
The female of this spider appears, at first sight, to be identical with D. spinipes, 
Marx, from Florida. The figure of the vulva, however, given by Marx, is, curiously 
enough, identical in shape with that of the next species, D. auritus, which is obviously 
quite a distinct form. 
2. Deinopis auritus, sp.n. (Tab. XXXIV. figg. 3, ¢; 4, 4a-e, 2.) 
Type d, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 14, @ 15 millim. 
Hab. Mexico, Jalisco (Dugés). 
One would be inclined to treat this spider as generically distinct from the preceding 
species, but without being able at present to study the whole group thoroughly, I leave 
it under Deinopis. 
Fam. ULOBORIDA. 
The spiders comprehended in this family probably have no near relations amongst 
existing forms; so that it is difficult to place them in any system of classification. 
They represent possibly the survivors of larger groups, the majority of whose members 
have long since died out. 
The three genera represented in our collection may be distinguished as follows :— 
GENERA. 
a. Calamistrum occupying only the basal half of protarsus iv. 
1. Central posterior eyes nearer to each other than to the 
lateral posteriors . . . . . . - « «+ « Uxosorus, Walck. 
2. Central posterior eyes much further from each other than 
from the lateral posteriors . . . os + + . « » . ARiston, O. P.-Cambr. 
6, Calamistrum occupying almost the whole length of protarsus iv. Mu1acrammopss, O. P.-Cambr.
