Chelifer persimilis, n. sp. — This is extremely similar to C.cancroides. 

 The male differs at once from C. cancroides by having the margins of the 

 abdominal segments more strongly produced behind, and almost all of the 

 segments are so produced (while in C. cancroides only a few of the basal 

 segments are produced, and these not half as much). The palpus is similar 

 to that of C. cancroides, but the tibia is more swollen on the inner margin, 

 and the hand is heavier and the fingers slightly shorter and more curved. 

 It is of the same size and coloration. 



Specimens from Pecos, New Mexico (Cockerell) ; Las Vegas, New 

 Mexico (Cockerell); Eagle Spring, Organ Mts., New Mexico, and Roswell, 

 New Mexico, Aug. (Cockerell). 



Chelanops partitas, n. sp.— Cephalothorax and palpi red-brown, 

 former paler behind. Cephalothorax fully one and a-half times as long as 

 broad j surface closely and minutely granulate, and with many short, 

 clavate hairs. Trochanter strongly bigibbose behind ; femur fully as long 

 as width of the cephalothorax, slightly concave in front near the tip ; tibia 

 one and a-half times broader than the femur, evenly convex on outer side, 

 inner side rather suddenly swollen and slightly tapering beyond ; claw 

 longer than the cephalothorax, hand about twice as broad as femur, hardly 

 as long as tibia, tapering to the stout curved fingers, which are fully as 

 long as hand ; fingers with fine simple hairs, rest of palpus with short 

 clavate hairs. Legs with short almost clavate hairs. Abdominal scuta 

 each with about eight clavate hairs on the posterior border. 



Length, 3 to 3.5 mm. 



From Pt. Yuma, Arizona. Related to C. Arizotie/isis, but not as 

 darkly coloured, smaller, and the fingers are plainly longer than the hand. 



Chelanops diver sus, n. sp. — Cephalothorax dark brown, palpi dark 

 red-brown, body and legs paler, scuta± brown, but the basal three are only 

 brown near the middle. Cephalothorax barely longer than broad, densely 

 granulate, with extremely short, almost clavate hairs ; groove behind the 

 middle, its ends curving forward. Palpi not as long as body, very heavy ; 

 femur rather broadest near base, as long as width of cephalothorax ; tibia 

 almost as long as femur, outer side evenly convex, inner side suddenly 

 swollen and then nearly straight, barely broader than the femur ; claw 

 longer than cephalothorax and mandibles, hand very broad, about twice 

 as broad as femur, broadest at base and tapering to the fingers, which are 

 barely longer than width of hand, all with short fine hairs, those on femur 

 and tibia almost clavate. Legs with short, simple hairs. Abdomen rather
