Mr. R. I. Pocock on East- African Millipedes. 437 



paler keels and a pair of indistinctly defined paler spots on 

 the dorsal surface of the hinder half of the segments ; legs, 

 antennae, and ventral surface a uniform pale ochre-yellow. 



Body broad, nearly parallel-sided, about five times as long 

 as wide, its upper surface shining and nearly smooth, finely 

 punctulate. 



Keels well developed, nearly horizontal, though with the 

 posterior angle slightly tilted; the anterior angle convexly 

 rounded, the posterior acutely produced, though only in the 

 last five segments is the hinder border directed backwards ; 

 margin around the pore considerably thickened. 



Pores looking obliquely upwards and outwards on segments 

 5, 7,9, 10, 11, &c. 



The dorsal 1 area between the keels strongly convex. 



Tail triangular, with squarely cut apex and an angular 

 tubercle on each side in front of it. 



Lateral surface of segments finely shagreened ; a distinct 

 inferior crest visible as far as the seventh or eighth, then 

 dying out and, at most, represented by a small tubercle. 



Sternal areas wider than long, longitudinally impressed 

 and, at the posterior end, transversely impressed between the 

 legs, the anterior of which are connected by a ridge ; the 

 hinder border studded with long coarse bristles ; in the last 

 leg-bearing segment the pieces of the sternum that support 

 the legs of the last pair are coxiform, the distance between 

 the coxae of the legs being less than the length of one of the 

 coxse. The sternum of the fifteenth (in the male) is furnished 

 in front with a forwardly directed, small, triangularly pointed 

 tooth, and a low tubercular tooth at the base of the posterior 

 leg ; that of the seventh produced posteriorly into a widely 

 rounded basin-shaped hollow, for the reception of the copu- 

 latory apparatus ; sternum of sixth with an anterior median 

 triangular tooth, directed obliquely forward and downward. 



Legs with strong claw, hairy, especially the lower surface 

 of the two basal segments, which have at least one long seta 

 mixed up with shorter ones; tarsus of the first six pairs with 

 an apical pad. 



Copulatory organ with its distal portion curled backwards 

 beneath the proximal portion (for the rest see figure) . 



Measurements in millimetres. — Total length 25, width 5. 



Lcc. Mkonumbi. A single male example. 



it will fell into one of the many genera which Mr. O. F. Cook has re- 

 cently projected into literature. Most of these, without diagnoses and 

 without type species, are at present nomina nuda ; but we feel confident 

 that the publication of them will not be long delayed.
