156 Mr. R. I. Pocock on new Species of Chilopoda. 



anteriorly, swollen, convex, and very hairy posteriorly, its 

 inner surface very flat, its inferior edge being furnished 

 throughout its length with fifteen very minute close-set 

 denticles ; first tarsal segment a little shorter than the tibia and 

 more slender, but closely resembling it in shape ; there are, 

 however, fewer hairs on its lower surface and the inferior 

 edge of the inner surface is furnished in front with six much 

 larger denticles ; second tarsal segment longer than the first 

 and slender, its inferior surface deeply excavated anteriorly 

 and carinate posteriorly ; claio simple. 



Legs long and hairy, the twentieth pair longer and stouter 

 than the preceding pairs. 



Lengtli '2\'6 millim. 



A single specimen from Madeira, collected by my friend 

 and colleague Mr. W. H. Ogilvie-Grant. 



This species is closely allied to the common European 6V. 

 kortensi's, but appears to differ in the armature of the anal 

 legs. Thus on the tibial segment the spines are very much 

 smaller than on the first tarsal and are fifteen in number, 

 whereas in hortensis these spines are approximately as large 

 as on the first tarsal and vary in number up to ten. More- 

 over I have never seen a specimen of hortensis with anal legs 

 of the shape that this species exhibits ; in this particular Cr. 

 atlantis approaches Cr. cultratus of C. Koch. This last, 

 however, may be at once recognized by its sulcate head-plate 

 &c. 



Cryptops spinipes, sp. n. 



Colour ochraceous. 



Body slender, punctured and hairy. 



Head marked with two very fine anteriorly diverging sulci. 



Anteyime attenuate, hairy throughout, composed of 17 stout 

 segments. 



The first tergite marked in front with a transverse evenly 

 arched sulcus ; not distinctly sulcate longitudinally ; over- 

 lapping or overlapped by the head. 



Maxillary coxa- with anterior border angularly excised in 

 the middle and furnislied on each side with about five setaj. 



Tcrgkes (except the first three and the last two) marked 

 with tiie four normal sulci, all (except the last) with unraisod 

 margins. 



ISternites (except the first and the last three) marked witli 

 an anterior longitudinal sulcus and a complete transverse 

 sulcus, the posterior limb of the normal cross- shaped mark 

 being very indistinctly defined.
