476 Mr. R. T. Pocock on some new or 



keels obsolete only on the fourth, strong on the first and 

 second, weaker on the third, finely granular on the first ; 

 inferior lateral keels weakly granular on segments 1-4; 

 superior lateral keel of fifth smooth, not granular ; vesicle 

 nearly smooth, finely and closely granular below, not so wide 

 as in 11. lunatus. 



Chelce much as in the latter, but the hand smaller and 

 quite smooth; immovable finger lightly excavated at base; 

 width of hand exceeding that of brachium, a little less than 

 length of underhand, the latter about two thirds the length 

 of the movable finger. 

 Pectinal teeth about 18. 



Femora and patellar of third and fourth legs distinctly 

 granular. 



cJ . — Like the female, but with the sterna finely coriaceous, 

 the tail a little longer relatively, and the vesicle more length- 

 ened ; chelae with hand at most a little shorter than in female, 

 but the immovable finger with strong lobe and basal exca- 

 vation, so that when closed a distinct wide space is left between 

 the base of the fingers. 

 Pectinal teeth 19-21. 

 Measurements in millimetres. —

 Simons) . 



Apparently allied to H. maculatus, Thor. (Atti Soc. Ital. 

 Sci. Nat. xix. p. 186, 1876), from Callao, which also has the 

 median keels present on the last abdominal sternum and on 

 the first three caudal segments, but differing in having the 

 upper edges of the fifth caudal segment smooth and not densely 

 granular. 



Hadruroides leopardus^ sp. n. 

 (Typical lowland form.) 



$ . — Colour yellow, spotted and banded with black ; sides 

 of carapace banded with black ; frontal area with median 

 stripe; terga yellow, marked with four black spots and a 

 black lateral margin ; sterna pale, the last only with two 

 dark lines on the keels, last marbled with black at the sides, 

 spotted below ; legs and chelae spotted with black. 



Trunk finely granular above, frontal area smooth ; sterna 

 smooth, the last granular laterally and furnished with a pair 

 of lateral granular keels.
