annulate witli dark. Cheliccra; pale brown. Dorsum of abdomen dark grey along 

 sides, the median region light reddish ivilh a series of yellow spots along each edge; 

 sides of abdomen yellowish grey lightly spotted with black; venter limited on each 

 side by a longitudinal dark line, the intervening region almost immaculate. Posterior 

 eyes equidistant, not fully their diameter apart. Anterior median eyes much smaller 

 than the laterals, near their radius apart, a little nearer to the laterals. Palpal organ 

 represented in pi. 4, f. 1.

Distinct from other North American species especially in the structure of the male 

 palpus. 



CLIBIONID/E 

 Ol'ioj schistus sp. nov. 



A species approaching O. peiiinsulaniis, known from Lower California, but dif- 

 fering in coloration and various details of structure. While in peniniulantis the 

 carapace, labium, endites, chelicerc and legs are uniformly immaculate pale yellow, 

 in the present species the legs are darkened by numerous minute, dark, somewhat 

 purplish, spots which show a tendency to condense into an irregularly defined annulus 

 at proximal end of tibii; similar but fewer dots occur on carapace and chelicer.T, 

 but the sternum is immaculate. .Abdomen also very obviously darker and differently 

 marked, being densely spotted and streaked on the sides with blackish and less strongly 

 so above and below, the dorsum with a clear sagittate mark at base, followed by a 

 series of short chevron marks united along middle by a black line which is furcate 

 at its anterior end. Anterior eyes obviously larger than the posteriors; anterior median 

 eyes their diameter from the laterals and a little farther from each other, the eves 

 being more widely separated than in pcninsulanus. Posterior rows of eyes a little pro- 

 curved instead of straight, and the eyes much more widely separated than in the 

 species mentioned, the medians being three times their diameter apart and as far or 

 nearly as far from the laterals. Epigynum decidedly larger proportionately, with the 

 outer ridges posteriorly more thickened and elevated with reference to the inner rims, 

 etc. See pi. 4, f. 2. The palpal organ of male of similar structure but obviously 

 heavier; the proximal apophysis of tibia larger, distally clavately expanded and trun- 

 cate instead of being distally pointed with the setose edge long and oblique; the 

 anterior apophysis also differing as shown in pi. 4, f. 3. 



Length of female, 10.5 mm. Length of cephalothorax, 4.S mm. Length of lib. -f 

 pat. 1, 6.8 mm.; of tib. -f pat. IV, 6 mm. A male with cephalothorax 4.8 mm. long 

 has tib. -f pat. I, 8 mm. and tib. -f pat. IV, 6 mm. long. 



Type— M. C. Z. 3 54.

.Inyp/inrna irfhriipina sp. nov. 

 jWrt/c— Carapace and legs dull yellow, a dusky band along upper part of each side 

 of the former. Sternum, labium and endites also yellow, the chelicerx brown. Abdo- 

 men dull grey of slight yellow cast; dorsum with a few dark spots, the sides with 

 more numerous dark spots anil streaks; venter with some spots on posterior portion.
