Mr. R. I. Pocock on East-African Millipedes. 443 



impressions at the base of the antennae on the inner side. 

 Antennce with the segments thinner and longer, not strongij 

 expanded at their distal end. 



First tergite laterally more squared, crossed by two sulci, 

 the lower of which is only a little above the margin. The 

 rest of the segments finely striolate, but shining, not dull as 

 in Gregorii ; the areas in front of and behind the sulcus more 

 elevated than in the last-named. The apices of the anal 

 valves a little longer and rather thicker. 



Legs almost as in Oregorii, but less smooth at the sides 

 and above ; the trochanters not different. 



^ . With fourth and fifth segments of legs padded ; tro- 

 chanter of posterior leg of each segment thick and flattened 

 below, anterior compressed. First tergite laterally more 

 expanded, with anterior angle rectangularly rounded. 



Co-pulatory foot as in figure. 



Length about 70 millim. 



Number of segments 63 to 66. 



Loc. Ngatana (types) and Leikipia. 



Odontopyge Wilsoni, sp. n. 

 (PL XVIII. fig. 8.) 

 $ . — Colour (in alcohol) a tolerably uniform olive-brown, 

 with a deeper band running along the hinder border of the 

 segments. 



Head as in 0. semistriata, but more rugulose below, and 

 the transverse interocular sulcus weaker. 



Antennce with long and slender segments. 



Collum with one lateral sulcus in addition to the marginal 

 one, as in semistriata. 



Segments segmentate, striolate, and laterally striate, as in 

 the other species, and showing same position of pores. 



Anal segment shorter than in the preceding two species j 

 height of the valves exceeding the length of the tergite. In 

 the anterior third of the body the posterior legs of each 

 segment have their basal four segments flattened and exca- 

 vated below. 



(J . Face smooth and polished below ; first tergite laterally 

 expanded, convexly rounded anterior angle. 



Legs behind the seventh segment, with fourth and fifth 

 segments padded below, except quite at the hinder end of the 

 body, where the pad on the tlfth entirely dies off and that on 

 the fourth nearly so ; the coxa and trochanter of the posterior 

 leg of the segments behind the seventh expanded and flat- 

 tened below. 



Copulatory organ as in figure.
