The Pseudoscorpions of Sonili Africa. 113 



" This is a ground species, living under stones. The pregnant ? 

 makes a nest like that of Obisium musconnn, but of much rougher 

 material, with the usual lining of silk, attached to the under side of 

 a stone" (Godfrey in litt.). 



NOTE. After having examined a number of specimens from South 

 Africa, I have no doubt that G. olivaceus Tullgren is the same species 

 as G. senegalcnsis Balzan. Balzan's figure of this species agrees 

 very well, but there are some remarks in Balzan's description which 

 need to be taken into consideration. Balzan says of the cephalo- 

 thorax : " Sulco transverso, distincto." Tullgren, on the contrary: 

 " Querfurchen fehlen, die erste Furche ist aber angedeutet." In 

 another place, however, Tullgren says that the groove is " ziemlich 

 deutlich." In the South African specimens it may be different : in 

 some of them the groove is more distinct than in others. I should 

 prefer to express it thus : the transverse groove exists, but may 

 sometimes be only a little pronounced. Balzan says of the tibia 

 of the palps : " Superne et interne post petiolum, vix gibbosum." 

 Tullgren mentions no such thing, but this gibbosity is certainly 

 present also in his specimens. Balzan's figures of the galea show 

 that he had before him both $ and 5 , though he mentions nothing 

 about the sexes; Tullgren had only $ . 



The male has, however, some characters which Tullgren has had 

 no opportunity of seeing, not having had males for examination, nor 

 has Balzan observed these characters. Besides the shape of the 

 galea (observed by Balzan), which in the male is small and pointed, 

 with no teeth (Balzan seems to have drawn it rather too robust), 

 these characters are the following : the sexual region of well- 

 developed specimens is of a dark reddish-brown colour, sufficiently 

 dark to be seen with the naked eye ; femur and tibia of the palps 

 are on the inner side provided with a row of bigger tubercles of 

 which that next to the base of tibia is somewhat bigger than the 

 others ; this tubercle represents the gibbosity mentioned by Balzan 

 (see above), and is probably present in both sexes. The front 

 margin of cephalothorax in the male has, besides the central 

 sinuation, another smaller sinuosity on each side of this, the front 

 margin thus becoming quadridentate (in the ? there is only a 

 central sinuation, as Tullgren rightly observes). The hand of the 

 palps is a little more slender than that of the female. 



To the common description of the species ( $ and ?) may be 

 added : The coxa of the palps is, as Tullgren observes, truncate 

 in front ; the front margin is even a little concave, the inner corner 

 with a small point, the outer one with a very long bristle (if not
