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 chelicerae 

 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 laclcing these as in 

 Chemmis. 



Genotype. — A. sober sp. nov. 



This genus appears also to include Chemmis unicnlor 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. Chelicers 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, eves subequal; posterior median eyes about their diameter or a little 

 more from the laterals, three-fourths or less theit diameter apart. Epigynum as shown 

 in pi. 5, f. 5. 



Length up to 10.5 mm. Length of cephalothnrax, 4.5 mm. Length of tib. + pat. 

 I, 5 mm. ; of tib. -|- pat. IV, the same.

Anachemmis Ji>lichopus 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 tibias 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 pi. 5, f. 6. 



Male — Palpus shown in pi. 5, f. 7. 



Length of female, 10 mm. Length of cephalothorax, 4.5 inm. Length of leg I, 

 exclusive of coxje, 17 mm.; of tib. + pat. I, 6.5 mm.; of tib. — pat. IV, the same. 



Type— M. C. Z. 344. Cal.: Claremont. Win. .A. Hilton coll.
