442 Mr. R. I. Pocock on East-African Millipedes. 



Legs with lower surface of all the segments bristly, the 

 bristles longer at the distal ends of the segments ; upper 

 surface of the legs finely hairy, the hairs more conspicuous 

 upon the tarsus and upon the basal segments (trochanters) of 

 the anterior legs ; in the anterior half of the body the tro- 

 chanter of the posterior legs on each segment is flat below, 

 while that of the anterior leg is compressed. 



(^ . Eesembling female, but thinner, with the sixth seg- 

 ment a little expanded and the anterior angle of the first more 

 rectangular. 



Legs with fourth (antepenultimate) segment padded below, 

 the pad larger on the anterior legs, gradually disappearing 

 posteriorly and scarcely visible on the legs of the last six 

 segments. 



Copulatory foot as in figure ; anterior lamina long and 

 rather slender, notched inferiorly ; coiled portion consisting 

 of two main pieces — a double flagellum, of which the outer 

 branch is longer, stouter, and spirally coiled at the tip, while 

 the inner is much shorter, thinner and simply pointed, and 

 of a complicated semi-membranous sheath, also double, one of 

 the branches being leaf-like, with serrate edges and a bifid tip. 



Number of segments over 70 (71 or 72). 



Length about 85-90 milllm. 



Loc. Ngatana. Several examples. 



Odontopyge semistriata, sp. n. 

 (PI. XVIII. fig. 9.) 



Allied to the preceding in most structural details, but 

 certainly different in the following respects : — 



The sides and lower surface of the body reddish yellow, 

 but the posterior half of the upper surface ornamented with a 

 black transverse stripe which extends down to the pore, 

 though it thins off just above this point ; when the body is 

 spirally coiled these black bands are separated by the yellow 

 colour of the anterior part of the segments, but when the 

 body is extended, as in crawling, the black stripes are con- 

 tiguous or nearly so, so that the upper surface of the body 

 appears to be black ; the first tergite with its posterior two 

 thirds black above ; anal tergite black above ; valves black 

 above; face black, rather paler inferiorly; antennaj fuscous, 

 with the basal two segments pale ; legs entirely yellow. 



? . Head resembling that of 0. Gregoriij but with the 

 transverse stria between the eyes much deeper, very con- 

 spicuous ; the inner angle of the eye more acute ; the area 

 above the labrum distinctly grooved and roughened. No
