62 Mr. R. I. Pocock on new 



the first a female of one and the same species. It is a well- 

 marked form resembling Rh. longipes in some respects, such 

 as in possessing marginate tergites and spined anal legs. It 

 differs, however, from this species in having bisulcate sternites 

 and a well-developed spinous process on the anal femur. 



Scolopendra (?) cuivis, sp. n. (PI. IV. fig. 7.)

 ridge.

 longitudinal depression and an anterior depressed area ; pro- 

 sternal plates moderately long, not wide, in contact, each 

 bearing four teeth, of which the three internal are more or 

 less fused ; basal tooth on a level with the prosternal plates, 

 well-developed and subdentate; claw very stout, powerful 

 and curved.

 marked in front with a conspicuous but fine transverse sulcus ; 

 rest of the tergites smooth and (except the last) strongly 

 bisulcate, from the eleventh strongly marginate. 



Sternites smooth and strongly bisulcate.

 sulcus, posteriorly depressed in the middle ; pleurce very finely 

 porous, with one posterior superior spine, the process short 

 but distinct, and armed with four strong spines ; sternite
