1900.] INSECTS AND ARACHNIDS FROM SOMALII.AND. 55 



outer and one inner ; finger a little more than twice the length of 

 the underhand. 



Legs w ith granularly crested femora ; the feet with two rows of 

 hairs below. 



Pectinal teeth 21. 



Genital operculum considerably longer than sternum. 



Measurements in millimetres. Total length 31 ; length of carapace 

 3-5, of tail 17*5 ; length of movable digit 3. 



Loc. North-west ISomaliland (Berbera or Hargaisa). A single 

 specimen (type) in the British Museum. 



In size and some points of structure this little Biiihus approaches 

 Nanohuthvs anclersoni Poc, obtained at Duroor to the north of 

 Suakim (Jouru. Linn. Soc, Zool. xxv. p. 314). The dentition of the 

 mandible and of the digits of the chelae, however, is quite normal 

 for the genus Buihus. The most striking structural peculiarities 

 of the species are : (1) the obsoleteness of all the cephalothoracic 

 keels with the exception of the anterior median : (2) the coarse 

 but sparse punctuation of the last sternite and of the lower side of 

 the first caudal segment, accompanied as it is by the disappearance 

 of the median keels ; (3) the disappearance of the median keels on 

 the lower side of the 4th caudal segment. These characters do 

 not co-exist in any species known to me. Judging from the 

 structure of the inferior lateral keels of the 5th caudal segment 

 and of the inferior keels of the 2nd and 3rd segments, this species 

 belongs to the same category as B. occitanus.

Pamily Buthid.e. 

 Genus Uroplectes Peters. 



Uroplectes fischeri (Karsch). 



Lepreus fischeri, Karsch, Mitth. Miinch. ent. Ver. iii. p. 124 

 (1879). 



Loc. Barawa {Karsch), Turfa and Lummo (Donaldson Smith), 

 and Berbera and Hargaisa (C. V. A. Peel). 



To the south of Somaliland the typical form of this species is 

 replaced by two subspecies, one paler, the other darker than 

 U. fischeri typicus. The three may be contrasted as follows : — 



a. Hands entirely pale, body banded above as in 



Jisn-heri ty2>icus fi. flaviiaanus, subsp. 



h. Hands wholly black or at least lined with black [nov. 



and black at base of fingers. 

 a'. Terga yellow, with a pair of black spots ; cara- 

 pace and terga broadly yellow at the side ... fi. typicus. 

 h\ Terga mostly black, with a narrow median 

 and lateral marginal band, much less yellow 



at side of carapace fi- niqnmanus.
