The two specimens of this species that were obtained in North- 

 west Somalihand (at Berbera or Hargaisa) agree closely in 

 characters with those collected by Dr. Donaldson Smith at Lunimo 

 and Turfa, and discussed on pp. 400-401 of that author's account 

 of his expedition. One of Mr. Peel's specirilens is in the British 

 Museum, the other in the Hope Museum at Oxford. 



Genus Buthus Leach. 



EuTHUS CALYiCBPS, sp. n. (Plate IV. figs. 3-3 a.) 



Colour (dry specimen) : trunk blackish yellow ; appendages 

 uniform pale yellow. 



Carapace weakly granular ; keels almost entirely obsolete, only 

 the anterior median distinct but failing to attain the front border 

 of the carapace. Tergal plates rather coarsely granular ; keels 

 normal and granular. Sternal plates smooth and polished ; the 

 last very finely granular at the sides, polished and rather coarsely 

 but sparsely punctured in the middle ; the lateral keels almost 

 obsolete, represented by about three larger granules. 



Tail of medium thickness, nearly five times the length of the 

 carapace, posteriorly narrowed; the sides and upper surface of the 

 segments nornially crested, the iutercarinal spaces finely granular ; 

 the median lateral keel complete on the 2nd and almost complete 

 on the 3rd segment ; lower surface of ]st, 2nd, and 3rd segments 

 rather coarsely but strongly punctured with setiferous pores ; the 

 median keels of the 1st obsolete, those of the 2nd and 3rd strong 

 and denticulated, increasing in strength posteriorly, the inferior 

 laterals of these segments also strong and denticulated, converging 

 posteriorly and fusing, like the medians, with a transverse granular 

 crest ; louer surface of the 4th weakly granular, without median 

 keels ; 5th segment without a trace of superior lateral keels, finely 

 granular below, with a few coarser granules intermixed, the median 

 keel denticulated; the laterals strongly denticulated, with at least 

 one large lobate tooth behind the middle of their length, ending 

 behind in a big subdivided lobe on each side of the anal aperture; 

 vesicle of medium size, smooth, punctured. 



CHieJa^ weak ; humerus granular above, normally crested ; bra- 

 chium smooth, weakly crested, anterior surface with two weakly 

 granular keels ; hand smooth, small, narrower than braehium, 

 movable digit with eight rows of teeth along the middle line, the 

 basal row long and rising right at the extremity of the segment, 

 the lateral teeth forming short oblique rows of three each, two
