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

 the underhand. 



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

 hairs below. 



Pectlnal teeth 21. 



Qt nital operculum considerably longer than sternum. 



Measurements in millimetres. Total length :J1 ; length of carapace 

 3*5, of tail 1 7*5 ; length of movable digit 3. 



Loc. North-west Somaliland (Berbers or Hargaisa). A single 

 specimen (type) in the British Museum. 



In si/e and some points of structure this little Butlius approaches 

 Nanobuihus andersoni Poc., obtained at Duroor to the north of 

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

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

 for the genus Bufhus. 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 mediae keels ; (3) the disappearance of the median keels on 

 the lower side of the 4th caudal Begment. 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. oecitanus.
