exceeding the anterior medians, the row typically a little recurved. Area of median 
eyes narrower in front than behind where the width almost equals the length. Clypeus 
narrow, not exceeding the anterior eyes. Later eyes contiguous. Labium, endites and 
sternum essentially as in Chemmis, but the lower margin of the furrow of chelicera 
armed with three teeth instead of two. The anterior tibiae bear similarly five pairs 
of long spines beneath; but the metatarsi bear three pairs instead of two. The 
posterior tibiae bear two median dorsal spines instead of wholly lacking these as in 
Chemmis. 
Genotype—A. sober sp. nov. 
This genus appears also to include Chemmis unicolor of Banks from Arizona in 
addition to the two species here described. These species are more uniformly colored 
than the species of Chemmis; and, in having all markings nearly obliterated, contrast 
conspicuously in general appearance with the members of that genus. 
Anachemmis sober sp. nov. 
Female—Carapace dusky over a brown to light chestnut ground. Legs light brown 
to light chestnut, without markings. Sternum light brown or testaceous. Labium and 
endites darker, pale across distal ends. Chelicere chestnut. Abdomen dusky brown or 
blackish, with a median dorsal light line at base extending to near middle, a light 
spot on each side opposite each end and two or three pairs of light spots farther caudad, 
but these light marks commonly vague; venter paler, showing a yellowish back- 
ground darkened by dark psots. Anterior row of eyes nearly straight; the median 
eyes much smaller than the laterals and especially than the posterior medians, their 
diameter apart and about half as far from the laterals. Posterior row of eyes a 
little recurved, eyes subequal; posterior median eyes about their diameter or a little 
more from the laterals, three-fourths or less their diameter apart. Epigynum as shown 
Impl. ssi. 5. 
Length up to 10.5 mm. Length of cephalothorax, 4.5 mm. Length of tib. + pat. 
I, 5 mm.; of tib. + pat. IV, the same.

lection received from Prof. Hilton. 
Anachemmis dolichopus sp. nov. 
Female—Contrasts in general appearance with the preceding species in its very 
long legs and much lighter color. The carapace, sternum and legs are yellowish 
brown without markings, but the legs are somewhat darkened over tibie and distal 
joints. The abdomen is uniform grey throughout, with no definite markings. The 
anterior row of eyes slightly recurved; median eyes much smaller than the laterals, 
about their diameter apart, closer to the laterals. Posterior row of eyes straight; 
medians smaller than the laterals, about their diameter apart, nearly half as far again 
from the laterals. Legs very long. Readily distinguishable by the form of the 
epigynum as shown in pl. 5, f. 6. 
Male—Palpus shown in pl. 5, f. 7. 
Length of female, 10 mm. Length of cephalothorax, 4.5 mm. Length of leg I, 
exclusive of cox, 17 mm.; of tib.-+ pat. I, 6.5 mm.; of tib.+ pat. IV, the same.
