EXPEDITION TO SOKOTRA: NEW GENERA AND SPECIES. 41 
Palpimanidz. 
Scelidomachus, gen. nov. 
Genus of the section Chedimew with the lateral eyes in contact, and allied 
to Steriphopus, Boagrius, and Sarascelis in having the anterior median eyes at 
least twice as large as the laterals, and the ocular quadrangle nearly parallel 
sided ; also further resembling Sferiphopus in having the quadrangle nearly 
square (in Boagrius and Sarascelis it is much wider than long); but differing 
from it in having the eyes of the anterior line straight, by their inferior 
borders not recurved, and the anterior median eyes separated by a space 
which barely equals their radius (in Swrascelis the space equals the diameter of 
the eye). 
(3) Scelidomachus socotranus. 

3. Colour.—Carapace and sternum deep red, legs of Ist pair paler 
yellowish red, those of the remaining pairs still paler, abdomen of a uniform 
reddish grey or testaceous tint. 
Carapace coriaceous above, closely granular at the sides, its upper surface 
between the eyes and the fovea lightly convex longitudinally, scantily clothed 
with short black hairs. Zegs normal for the family ; femur and patella of 1st 
pair sparsely but distinctly granular beneath and on the inner side ; tibia, 
protarsus, and tarsus normally scopulate on the inner side ; the protarsus, 
which is about as long as the tarsus, armed apically beneath with a short 
downwardly directed spiniform process ; 2nd, 3rd, and 4th legs unspined, 
covered with greyish black hairs, the tarsi and protarsi apically scopulate. 
Sternum granular ; abdomen thickly covered with a coating of short olive 
grey hairs. Palpus with femur slender ; patella short, subglobular ; tibia 
much larger than patella, twice its length, and nearly or quite three times its 
height, also subglobular ; tarsus almost as long as patella and tibia taken 
together, slender and cylindrical distally ; the palpal organ running out into 
a forwardly directed process with a dilated tridentate extremity ; a mem- 
branous lobe at its base and a subspirally twisted shorter piece on its inner 
side. 
Total length, 6 mm. 
Habitat. Sokotra (Dahamis, 350-1000 ft. (Type) ; Jena-agahan, 1200-2500 
ft.). 
Zodariidz. 
(4) Capheris insularis. 
2. Colour.—Carapace deep castaneous; legs infuscate, banded and mottled 
with paler markings ; protarsi and tarsi yellowish; abdomen deep greyish 
black above and at the sides and variegated with pale yellow spots, which 
posteriorly and laterally arrange themselves in definite transverse and vertical 
stripes ; lower side yellowish white, with two black stripes running longi- 
tudinally from the epigastric fold and dividing the pale field up into three 
broad yellow bands ; area in front of sternum black. 
Carapace high, higher in front of the fovea than on the ocular area. 
Eyes apparently arranged and practically of the same relative size and 
distance apart as in the only other species of the genus, the South 
African Capheris crassimanus, Sim. (see Simon, Hist. Nat. Araignées, Vol. 
I., p. 417, figs. 383 and 384). Legs longish and rather slender; Ist and 
2nd pairs unarmed, except for a single apical spine on the lower side of 
the 2nd protarsus; 3rd and 4th pairs with patella, tibia, and _protarsi 
strongly spined, the patella with one pair of spines only, the tibia and 
protarsi with many. Palpus with the tarsus strongly spined inside and
