UROCTONOIDES. gen. nov. 
Like [ 'rocfomis but differing in having the lower margin of movable 
finger of chelicera wholly smooth. Median lamella of comb similarly 
divided beyond base, the sclerites fewer, typically four. Fingers of hand 
of palpus with single row of granules, with a few larger lateral granules 
on each side. Stigmata oval.

Male. — The type, which is lacking the tip of the cauda, is dark red- 
dish brown, almost black, the legs paler, the end joint paler than others. 
Anterior margin of cephalothorax verj' slightly excavated, much less 
deeply than usual in Urodoniis mordax, and the bottom of the excavation 
extending forward in an obtuse angle, the apex of which is in line with 
the margin at the side. Median longitudinal furrow obviously deeper 
and wider both in front and caudad of eye-tubercle than in that species. 
Surface of carapace posteriorly and on side region strongly granular, the 
eve-tubercle and the area in front of it coarsely densely punctate. Dor- 
sal surface of abdominal segments also granular, the ventral surface 
appearing smooth and shiny, under the lens seen to be more finely punc- 
tate. Last ring of preabdomen without any keels or tubercles or granules 
beneath. Keels of femur of palpus coarsely granular or tubercular, also 
those of tibia; inter\'ening surfaces strongly punctate. Posterior border 
of ventral surface of tibia with five trichobothria. Keel from immovable 
finger of hand obsolete; surface of proximal region of hand in general 
with low tubercles or granules arranged more or less in a netw^ork; 
surface of fingers punctate. Fingers wnth a conspicuous lobe, that of 
movable one obtuse, that of immovable one acute. Teeth of comb seven 
in number. 
A form apparently nearly the same size as U. viordax Thorell.
