riorly emarginate; legs long and slender, about as long as the last 
six segments of the body; femur armed in its basal half with three 
or four strong spines, one or two close together on the upper inner 
edge, and 2 on the under surface, one outer and the other inner ; 
the rest of the femur and of the other segments unarmed ; protarsus 
without a spur, the femur and patella with a transverse annular 
groove at the distal end beneath. The rest of the legs armed with 
two protarsal spurs, except those of the 20th pair, which have but 
one. 
Length up to 53 mm. 
Locality. Loga in the Arusa Galla country (3,400 ft.) 
Recognizable from all the described species by the armature of 
the anal legs ; but most nearly allied apparently to R. dongicoruts, 
Poc. from Socotra.

CLASS DIPLOPODA (MILLIPEDFS). 
Astrodesmus concolor, sp. n. 
Very closely allied to Astrodesmus contortus, POC.,' obtained by 
Dr. Gregory at Mkanumbi in East Africa, but broader, owing to 
the greater size of the keels, of which the margins are thicker, so 
that when viewed from above the pores appear to look more 
upwards, a larger piece of the border being visible below the pore; 
the copulatory organs of the male are also different, the apical 
expansion being broader. In both the species there are three 
1 Eurydesmus contortus, Poc., Ann. Mag. Nat. Hist. (6), xvii. p. 436; the 
apex of the copulatory organ in this species is not accurately figured.
