62 Mr. R. I. Pocock on some 



when viewed from above, straight when seen from the front, 

 the lower edge of the laterals being on the same level as that 

 of the median; the anterior median about as large as the eyes 

 of the hinder row, but much smaller than the anterior laterals 

 and considerably nearer to them than they are to each other, 

 the space between them being about equal to their diameter ; 

 space between the anterior and posterior lateral a little greater 

 than the diameter of the former ; the clypeus a little longer 

 than the diameter of the anterior lateral eye. 



Legs long and slender, 2, 1, 4, 3 ; their spine-armature 

 approximately the same as in Palystes Johnstoni and the rest. 



The vulva of large size and projecting vertically downwards. 

 (For structure, see figure.) 



Measurements in millimetres. — Total length 13 ; length of 

 carapace 6, width 5 ; length of first leg (from base of femur) 

 24, of second 24'5, of third 19, of fourth 21. 



Log. East London (H. A. Spencer). 



Judging from M. Simon's diagnosis of Penaretus, this 

 species differs from the Oriental members of the genus in 

 having the legs longer and the mandibles weaker, less geni- 

 culate, and normally hairy from base to apex. 



Olios Spenceri. (PI. VIII. fig. 6.) 



2 . Colour. — Carapace pale castaneous, clothed with whitish 

 hairs ; mandibles black, maxillaa and labium chestnut ; abdo- 

 men clothed above with yellowish-white hairs, with a median 

 black stripe consisting of triangular spots, and mottled at the 

 sides with blackish spots and short stripes ; pale below, 

 vulva deep black. Palpi reddish yellow, tarsal scopula 

 fuscous; legs reddish yellow, clothed with yellowish-white 

 hairs, scopulas fuscous ; tibias with two faint fuscous bands. 



Carapace as wide as long ; moderately convex, its width 

 just equal to the length of tibia of first leg. Eyes of poste- 

 rior row straight, s; bequal, and nearly evenly spaced ; eyes 

 of front row closer together, subequal, the median a little 

 nearer each other than each is to the lateral, the space between 

 median and lateral about equal to a diameter. 



Mandibles sparsely hairy ; armed below with 4 teeth be- 

 hind and 2 in front. 



Palp : femur with a cluster of 5 spines above distally ; 

 patella and tibia with 1 external and 1 internal ; tarsus with 

 1 external and 3 internal. Legs 2, 1, 4, 3 ; the second 

 excelling the first by its tarsus; the third and fourth only 

 slightly unequal ; femora of first, second, and third armed 

 above with 8 spines (3, 2, 3), of fourth with G (3, 2, 1) ;
