Posterior spinners with the apical segment about half as long as the pen- 
ultimate segment. 
Carapace as long as' the metatarsus and tarsus of the first leg, and about 
equalling the metatarsus and one-third of the tarsus of the fourth leg. 
Pedipalp. Tibia with an inferolateral row of three spines widely separated 
from each other, on the inner side : of these, the middle one is longest and the 
proximal one weakest: on the same side there is also a more dorsally situated 
spine near the apex of the segment. Patella with a single weak spine or strong- 
bristle near the apex on the inner side. Femur with three strong spines 
superiorly near the distal end. 
Colour. Appendages dull brown, carapace dark chestnut brown, abdomen 
infuscated superiorly. 
Measurements. Total length 10-5, length of carapace 4-6, breadth of carapace 
3*2, length of metatarsus of first leg 2-65, length of metatarsus of fourth leg 4. 
A single female example obtained at the same time has the following 
characters: dentition essentially similar to that of male, the inner main row 
having nine or ten moderate sized teeth in a series which is interrupted in 
several places by an intervening minute tooth: the outer row includes 5-8 
rather small teeth in a continuous series, at the base of which is a number of 
minute denticles, the distal tooth of the outer row being opposite to the 
interval between the third and fourth inner teeth counting from the apex: 
labium with ten cusps : maxilla with about twenty-two cusps : fovea procurved : 
patella III with a row of five stout spines along the anterior surface, the most 
basal one being very short: posterior sternal sigilla slightly more than twice 
their length apart: metatarsus I with two apical spines inferiorly and two 
along the outer side below: the two anterior pairs of tarsi are scopulate, but 
not densely so, and metatarsi I and II are not scopulate: apical segment of 
posterior spinners slightly more than half as long as the penultimate segment : 
the claws on all the legs have the usual double series of teeth, but the more 
distal row is composed of two or three very small teeth. 
Colour. Carapace and appendages brown : abdomen infuscated superiorly, 
with numerous unarranged pale spots which break up the original dark tree 
pattern. 
Total length 15, length of carapace 5-15. 
The absence of scopulae on the anterior metatarsi of the female is note- 
worthy, for, in females of all other species of this genus known to me, a scopula 
occurs on the distal portion of the first metatarsus at any rate: it is just 
possible that the specimen now described is immature, and that a few scopular 
hairs may occur in the adult female. 
Spiroctenus spinipalpis sp. nov. (text fig. 6 a and b, PL III, fig. b). 
This species is based on an adult male example from the hill above Ruby 
Creek, Swaziland, where it was collected by Mr A. Roberts (18. v. 1916). It 
can be distinguished at once from any of the described species of Spiroctenus 
through the presence of strong spines on the tibia of the palp. It is probably 
closely related to the Barberton species described by me under the name of 
Paromostola (?) pardalina ( Records Albany Museum, 11. p. 424), of which only 
the female is known (PI. Ill, fig. a). 
Legs. Tarsus IV scopulate almost to the base on each side. Metatarsus I 
almost straight, being only slightly bowed towards the base in side view, with 
two spines at the apex inferiorly, three spines on the anterior surface and four
