sides, finely punctured ; precoxal plates longish, narrow, 

 parallel or diverging, armed with four teeth, the inner fused; 

 femoral tooth indistinctly dentate. 



Tergites smooth, punctulate, from the seventh marginate, 

 from the fifth to sixth bisulcate ; the last without any median 

 groove. Sternites smooth, marked with a pair of median 

 impressions, one in front of the other and longer than it, in 

 addition to two normal sulci ; the last two without sulci. 



Anal pleura? with the process short and tipped with two 

 spines ; anal legs of average length and thickness ; femur 

 without any spine at its distal end, the other spines few in 

 number, 1 or 2 on the upper inner, 2 or 3 on the under inner 

 edge, and 2 or 3 on the under outer. 



Legs without tarsal spurs ; claws basally spined. 



Length up to about 62 millim. 



Loc. Merifano and Leikipia (J. W. Gregory}; also Mom- 

 basa (D. J. Wilson, type). 



This species is unmistakably nearly related to 0. nudum, 

 Poc. (Ann. & Mag. Nat. Hist. 1890, v. p. 247), from 

 Madras, the form of the head and maxillipedes, the absence of 

 spurs on the tarsi, the grooving of the sterna, &c. being the 

 same in the two species. In 0. nudum, however, the terga 

 are wrinkled and subgranular and there is a spine close to the 

 apex of the femur of the anal leg. Possibly these distinc- 

 tions will break down with the discovery of fresh specimens. 



Part III. — Millipedes (Diplopoda). 



POLYDESMOIDEA. 

 Orodesmus forceps, O. F. Cook. 

 Loc. Leikipia. One example (type). 



Orodesmus ellipticus, 0. F. Cook. 



Loc. Ngatana. One example (type). 



During a recent visit to the British Museum Mr. O. F. 

 Cook, at my request, examined these two specimens and 

 described them as representatives of two new species. So far 

 as I know, the descriptions have not yet been published ; but 

 doubtless they will shortly appear.
