Pedipalp. The tibia of the pedipalp carries from three to six spines on the 
lower surface, and the metatarsus two. The cylindrical bristles on the dorsal 
surface of the tibia of the palp are very short in the basal half of the segment, 
long in the distal half. 
Colour. The general colour is pale yellow. 
Measurements. Total length 12-2, length of palp 15-5, length of flagellum 
i-i5- 
An adult female captured at the same time has a general resemblance to 
the male, but the limbs are shorter and weaker. The third tooth of the upper 
jaw is of moderate size: the outer row comprises seven teeth and the inner 
row three, the two basal ones of the latter being close together: the inter- 
mediate tooth of the lower jaw is small. On the tibia of the pedipalp there 
are four long spines which are relatively weaker than in the male, and two or 
three occur also on the tarsus. The surfaces of the body are unfortunately too 
rubbed for descriptive purposes. 
Total length 11, length of palp 9-4. 
Order ARANEAE. 
Family AVICULARIIDAE. 
Acanthodon monticoloides sp. nov. 
The types of this species are single specimens of the adult male and female 
collected at Pigg’s Peak, Swaziland, by Mr A. Roberts (16. v. 1916). It is 
related to A. monticola mihi (. Annals Trans. Mus. v. p. 185), but is easily 
distinguished therefrom in the absence of spinules or spinuliform setae on 
coxa III in either sex. 
Male. 
Chelicerae. The inner row of teeth is represented by a single fairly large 
tooth: the main row has seven teeth. 
Pedipalps. Tarsus with one long stout spine near the apex superiorly and 
several weaker ones. The band of spines margining the excavation of the 
tibia is interrupted in the middle: there are nine or ten spines distally and 
10-14 proximally. 
Legs. Coxa III with a strip of scattered setae along its post-ventral 
border, a few of these setae being much longer and rather stouter than the 
rest, though none can be described as spiniform. Tibia I scarcely stouter than 
the patella, except near the apex, but decidedly stouter than the metatarsus, 
equal to the metatarsus in length, its distal tubercle bearing a long flattened 
black process with rather blunt apex : there is a row of 3-5 rather weak spines 
along the outer side inferiorly. Metatarsus I not bent nor incrassated in any 
part of its length, practically straight: on the outer side inferiorly is a row of 
five long and fairly stout spines, and on the inner side inferiorly are two such 
spines. Tarsus I with one spine anteriorly and one or two posteriorly: in- 
feriorly it is thinly scopulate. Tarsi II— IV all scopulate to the base. Band of 
spinules on anterior side of patella IV stretching over about three-fifths of the 
length of the segment and comprising only about a dozen spinules. Patella III 
with nine or ten spinules on the anterior surface, including the several short 
spines on the apical edge, also with one weak spine on the dorsal surface and 
two or three at the apex posterodorsally.
