which are about one-seventh shorter than the diameter of the broadest portion 



of process F ? . The eighth tergite (PI. V, lig. 2) has a row of four 



bristles from the stigma downwards, and bears on the widened ventral portion 

 14 lateral bristles, and 12 or 13 apical marginal ones. The ninth sternite has only- 

 two or three small bristles on the sides. The lioad of the receptacxdum seminis 

 is almost exactly spherical. 



Two (^ (^ from Pirie, King William's Town, South Africa, off 

 Arvicanthis 'pxunilio, and one ? from the same locality off Mysorex 

 tenuis, all three specimens sent by the Rev. R. Godfrey. Type in my 

 collection.

A close ally of Gt. ansorgei. Roths. (1907), from Angola, but the 

 modified abdominal segments are different. 



In the (? the eighth sternite is very liroad at the apex ; the clasper (PI. V, 

 fig. 3, CI.) is produced into two lobes (P) of which the upper one bears three 

 long bristles. The lower lobe resembles a boot with the sole directed distad 

 and the toes upwards, there being one long bristle at the " heel." The movable 

 process (F) is very broad, and, at the apex, very strongly rounded, the apex 

 being more obtuse in one of the two specimens before me than in tlie other. 

 The process bears the usual I'ow of short, stout, pointed bristles at the apical 

 edge, and has six slender bristles, three long and three short, above the centre 

 of the distal {^= ventral) margin. The ninth sternite is so obscured in the 

 two examples that the outline of the ventral arm cannot be made out distinctly! 

 The segment appears to resemble that of Ct. ansorgei.

 Arvicanthis pumilio, sent by the Rev. R. Godfrey. Mr. Waterston 

 has kindly given me one of the specimens for my collection.
