the basal tooth is very wide, equalling in width about 5—9 

 of the remaining teeth together; movable digits of palpi with 

 13—14 rows of granules; total length about 90 — 118 mm. 



Distribution '). The typical form of this species 

 occurs in SE-Arabia (Yemen, Hadramaut, Aden); an east- 

 africau subspecies, P. Uosoma abijssinicus Poc, which 

 differs from the typical arabian form in having the inferior 

 lateral keels of the 5-th segment of the tail furnished poste- 

 riorly with distinctly enlarged teeth, extends from the Red- 

 Sea littoral into NE. Africa (Somali, Harar, Galla and Ogaden) 

 and thence is spread southwards to the mountain Kilimanjaro 

 and Mianzine (Pocock 1895, p. 312) in British East Africa. 

 This form occurs also in German East Africa (Moschi, Umbugwe 

 and Meru, according to Kraepelin 1913, p. 172),
