addition to the minute ones. Keels granular, incomplete 

 anteriorly. Third and fourth sternites with sparse granules 

 laterally ; fifth sternite granular and provided with four 

 granular keels. 



Tail. Keels distinct and granular in all segments. First 

 segment with ten keels, segments 2-4 with eight, fifth seg- 

 ment with five. Dorsal surfaces concave in segments 1-4 ; 

 fifth caudal segment slightly convex dorsally and provided 

 witii a narrow and shallow median groove ; posterior portion 

 of this last segment narrowed, but exceeding the vesicle in 

 breadth. Intercarinal spaces minutely granular; tiie granules 

 very sparse on the dorsal surfaces of tlie first four segments ; 

 fifth caudal segment more strongly granular. Vesicle hairy, 

 granules absent ; spine under aculeus laterally compressed 

 and terminating in a little knob. 



Palp. Hand with scattered granules on the inner edcre, 

 outer and inner keels of the dorsal surface miimtely but 

 distinctly granular; finger-keel granular only in that portion 

 which is situated on the hand itself. Movable finger pro- 

 vided with eigiit series of granules exclusive of the short 

 apical series, six series ending on the outer side in two large 

 granules, the last pair of granules situated at the base of the 

 prebasal series. Upper surface of the femur of the palp 

 minutely and densely granular. 



Pectinal teeth 19—20 in number. 



Measurements in mm. Length of cephalothorax 5'5, of 

 tail (vesicle excl.) 23, of movable finger 6, of hand-back 3*6; 

 breadth of hand 2'25j of tibia l"7o; total length 47. 



IJab. A ? specimen (the type) labelled " Berbera and 

 Durbar, ISomaliland, sea- level to 400 it.," and a second from 

 the Wagar Mountains behind Berbera, 3000-4000 ft. The 

 specimens were collected by Mr. G. W. Bury. 



Remarks. This species is closely allied to zamlonelli, 

 Borelli, from which it apparently differs in the granular keels 

 of the manus, the little knob terminating the spine under 

 the aculeus, tiie distinct keels of the last caudal segment, the 

 minute granules of the upper surface of the femur of the palp, 

 and in the fact that the movable finger is provided external! v 

 with two large granules situated at the base of the prebasal 

 series of granules. 



Genus ISOMETROIDES, Keys. 



There are two species of this genus in the collection of 

 the British Museum and each is represented by a single 

 specimen. I believe them to be the two described species
