This enumeratiòn will show, that the fauna of the Pseudoscorpions 

 of tropical Africa is rather little known, and that it should be of 

 great interest, if future scientific travellers in this continent would 

 collect these small and interesting animals, till now very much over- 

 looked.

No eyes, but distinct ocular spots. 



Bod}?- robust, elongate-oblong. 



Cephalothorax, palpa, tergites and sternites blackish brown, legs 

 light reddish browii, the interstitial parts light greyish brown. 



Cephalothorax: the posterior half almost parallelsided, the anterior 

 half gradually and roundly attenuated forwards, the front margin 

 roundly truncated. Cephalothorax somewhat longer than wide, smooth 

 and glossy, no transverse grooves. Hairs simple. 



Abdomen : tergites, especially the posterior ones, very minutely 

 shagreened. This shagreening, also mentioned later for some other parts 

 of the animai, consists in very fine stripes, limiting small irregular 

 pólygons, but the planes within are not elevated, the tergites thus 

 appearing smooth and glossy; the four anterior tergites and the two 

 last ones are entire, the fifth. with a beginning division behind, 6-9 di- 

 stinctly divided by a fine longitudinal line. Along the hinder margins 

 of the tergites there have been a row of hairs placed upon small light 

 tubercles (most of the hairs are lost), there also is or has been one 

 hair on the outer margin of each sclerite, but none at the margin of 

 the longitudinal line. The few hairs, which are left, are simple, some- 

 times a little uneven at the point. On the posterior somites there are 

 no hairs left. The sternites are minutely shagreened, like the ter- 

 gites, smooth and glossy; of the 8 sternites (the genital one excepted) 

 the first and the two last ones are entire, the rest divided longitu- 

 dinally. The hair as on the upper surface. 



Palps about as long as the body, robust, minutely shagreened on 

 ali the articles, even on the fingers for the most part, yet, on the 

 under surface and on the inner surface minutely granulated, some- 

 what glossy; the hairs of the palps rather long, pointed, on tbe fingers 

 no longer ones, perhaps lost. Trochanter stalked, about as long as 

 broad, the inner side strongly convex, behind there are two very 

 strong, conical protuberances, placed one on the upper and one on
