Scorpions from N. Somaliland. 181 



Wahlbergi ; tarsi armed almost as in Sc. viatori's &c. — that is 

 to say, the lobes are furnished with 2 spines, 1 median and 

 1 inferior, while behind on the lower surface there are 3 or 2 

 and in front 1, so that altogether there are 7 or 8 spines. 



Pectines furnished with II teeth. 



Measurements in millimetres. — Total length 71 ; length of 

 carapace 12, width 11'5, distance of eyes from hinder margin 

 7 ; length of tail 33 ; width of hand and length of movable 

 digit 9-3. 



A single, apparently not quite adult, female example ; dedi- 

 cated to Miss Edith Cole, who accompanied Mr. and Mrs. E. 

 Lort Phillips on the expedition. 



This is, perhaps, one of the best-marked species of Scorpion 

 tliat has been described of late years. From the structure of 

 the lower surface of the brachium and the spine-armature of 

 its tarsi and the dentition of the movable digit of the man- 

 dibles it falls into the East-African section, of which 8c. cavi- 

 manus and Sc. viatoris are the only examples known to me. 

 But from these it differs, as well as from all the other members 

 of the genus, in having the lower surface of the last abdo- 

 minal segment and tail thickly granular. 



Scorpio Phillipsii, sp. n. (PI. XI. figs. 3, 3 a.) 



$ . AUiedto Sc. Gregorii, Poc, but differs in the following 

 particulars : — 



Colour of the upperside of the trunk a brownish or reddish 

 yellow, the tail darker towards the extremity ; chelae reddish 

 yellow, with darker tubercles and green fingers ; legs and 

 ventral surface a uniform pale yellow. 



I'ail shorter than in S. Gregorii, being only a little more 

 than three times the length of the carapace, than which its 

 first and second segments are considerably shorter, the supe- 

 lior crest of the second, third, and fourth much less strongly 

 denticulate ; the vesicle, too, is a little differently shaped, 

 being distinctly wider than in Sc. Gregorii^ its width ex- 

 celling that of the third caudal segment and equalling that 

 of the second, while its height is less than the width of the 

 fifth segment. 



Chelce almost as in Sc. Gregorii, but the sculpturing of 

 the hand composed of much more distinctly defined tubercles 

 and spreading right over the posterior lobe of the hand ; the 

 upper surface of the hand, moreover, is much less convex, 

 wiiich gives it a sharper inner edge and a smaller height; 

 the lower surface, moreover, has about half of its area covered 

 with granules.
