Species of African Solifugfe and Aranete. 25 



posterior edge of the medians, subequal ; eyes of anterior line 

 straight by their inferior edges, the laterals one fourth longer 

 than the medians ; quadrangle scarcely narrowed in front, a 

 little longer than wide. 



Vulva smaller than that of P. distictus, formed of a horse- 

 shoe-sliaped sclerite, with a median piece wedged in between 

 the two arms and filling the posterior half of its space, the 

 anterior half being left empty and semilunar in shape. 



]\[easurements in millimetres. — Total length 13; length ot 

 carapace 1 , of first leg 26, of fourth leg 25.

Neither of these species falls, strictly speaking, into the 

 genus Pali/stes, and it is probable that they will have to 

 constitute a separate genus by themselves. The eyes of the 

 posterior line are distinctly recurved ; the ocular quadrangle 

 is only a little longer than wide and only a little wider behind 

 than in front ; the posterior lateral eyes are not elevated and 

 the anterior lateral eyes are only a little larger than the 

 anterior medians, which are as large as the posterior medians. 

 There is, however, considerable variation in the eyes in the 

 various species referred to this genus. The colouring, again, 

 of the two known species is quite unlike that of all the 

 South-African Pali/stes. The latter apparently may be grouped 

 as follows : — 



1. P. castaneus, li/cosinics, cultrifer, Whitecc, mega- 



cephahis, Ckaperi. 



2. P. lunatus, perornatus, Leppance. 



3. P. natalius {=Spenceri)^ Ellioti, Juhnstoni, Ilohneli, 



Fornasinii. 



4. P. distictus, scutatus. 



Sparassiis fonticola, sp. n. (PI. III. fig. 14.) 



Colour. Integument of the cephalothorax, jaws, and limbs 

 reddish yellow, scantily clothed with pale hairs ; abdomen 

 greyish yellow, faintly mottled. 



(Carapace as wide as long, a little shorter than patella + 

 tibia of fourth leg and than tibia of second, and about equal 

 to patella + tibia of third. Eyes of posterior line subequally 

 spaced, scarcely procurved^ laterals a little larger ; medians 

 about four diameters apart ; quadrangle wider than long, 

 narrowed in front ; anterior medians larger than posterior 

 medians ; eyes of anterior line straight by their centres, sub- 

 equally spaced ; medians larger than laterals, a little more 

 than a diameter apart.
