African Specimens of the Geynis Scorpio. 249 



Tail rather more than three times as long as cephalothorax. 

 Cephalothorax equalling in length the 1st + the 2nd + g of the 3rd 

 caudal segments. 



This species may be at once distinguished by the width of 

 the hand and by the remarkable depression it bears upon its 

 upper surface. I have seen two specimens of it — one (dried) 

 brought from Kilima-Njaro by Mr. M. J. Jackson ; the other, 

 wliicli, being preserved in spirit of wine, I have selected as 

 the type, brought by Capt. iSpeke from Urayamuezi. Both 

 appear to be males. The specimen from Kilima-Njaro is 

 smaller and slightly less granular than the other.

Cephalothorax. — Anterior margin circularly excised in tlie 

 middle line ; marked throughout its length with a shallow 

 median sulcus, which deepens and terminates immediately in 

 front of the hind margin ; laterally this deeper portion is 

 bounded by a smooth flat area corresponding with the usually 

 rounded elevations of other species ; ocular tubercle con- 

 spicuous, deeply cleft, and not continued before and behind 

 into distinct ridges ; anterior portion of cephalothorax nearly 

 smooth ; a smooth area extending from this anterior portion 

 along the upper surface on each side of the ocular tubercle 

 almost to the above-mentioned smooth flat area ; in the 

 immediate neighbourhood of the ocular tubercle behind and at 

 the sides are a few granules, in front of the tubercle the 

 cephalothorax is sparsely granular for some distance ; laterally 

 the cephalothorax is conspicuously though somewhat sparsely 

 granular, the granules appearing to be smaller and closer set 

 posteriorly ; central eyes a little nearer to the posterior margin 

 of the cephalothorax than to the circular excision ; the central 

 eye of the lateral series nearer to the anterior than to the 

 posterior eye of the same series. 



Tergites posteriorly and laterally beset with fine granules, 

 anteriorly smooth ; with very faint indications of a median 

 elevation and of an anterior right and left abbreviated sulcus ; 

 upper portion of last tergite smooth, with an anterior median 

 elevation and a posterior depression, bounded on each side by 

 a coarsely granular ridge, beneath which are smaller anterior 

 and larger posterior granules. 



Sternites perfectly smooth, sparsely punctured, each fur- 

 nished in front with a right and left abbreviated sulcus j the 

 posterior tergite furnished behind with very faint traces of 

 four smooth keels.
