Show 1900.] INSECTS AND ARACHNIDS FROM SOMALILAND. 55 outer and one inner ; finger a little more than twice the length of tbe underhand. Legs with granularly crested femora ; the feet wdth 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 Somaliland (Berbera or Hargaisa). A single specimen (type) in the British Museum. In size and some points of structure this little Buthus approaches Nanobuthus 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 Buthus. 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 tbe 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. 10. GENERAL LIST OF THE SCORPIONS OF SOMALILAND AND THE BORAN COUNTRY. By B. I. POCOCK. Family BUTHIU^E. Genus UROPLECTES Peters. UROPLECTES FISCHERI (Karsch). Lepreus fischeri, Karsch, Mitth. Munch, ent. Ver. iii. p. 124 (1879). Loc. Barawa (Karsch), Tttrfa and L u m m o (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, tbe other darker than U.fischeri tgpicus. The three may be contrasted as follows :-• a.. Hands entirely pale, body banded above as in fischeri typicus fi. flavimanus, subsp. b. Hands wholly black or at least lined with black [nov. and black at base of fingers. a1. Terga yellow, with a pair of black spots ; carapace and terga broadly yellow at the side ... fi. typicus. b'. Terga mostly black, with a narrow median and lateral marginal band, much less yellow at side of carapace fi- nigrimanus. |
