872 ME. R. I. POCOCK ON SCOE.PIOKS, PEDIPALPS, [NoV. 14, 



Measurements in millimetres. — Total length 31 ; length of cara- 

 pace 15, width 12 ; length of palp 17, of 1st leg 50, of 2nd leg 47, 

 of 3rd leg 38, of 4th leg 51 ; patella and tibia of 1st leg 26, of 4th 

 17, protarsus of 1st 12, of 4th 16. 



Loc. Benito Eiver {G. L. Bates). 



Rivalling the preceding species, C. Tcingsleyi and C. occidentalis, iu 

 size, and resembling them in the absence of the inferior apical pro- 

 tarsal spine of the 1st and 2nd leg ; but at once recognizable from 

 both by its coloration, especially of the lower surface of the 

 abdomen. It further resembles C. hingsleyi in having the carapace 

 shorter than the 4th protarsus and very much in the form and size 

 of the vulva, but differs from it and approaches C. occidentalis in 

 ha\ ing the carapace longer than the patella and tibia of the 3rd leg. 



The black patch on the lower side of the abdomen in C. sco])idatus 

 calls to mind the somewhat similar colouring found in Phoneutria 

 melanogastra of Bosenberg and Leuz (JB. Hamburg. Mus. xii. 

 p. 12, pi. i. fig. 14), from East Africa ; but the two species are 

 certainly quite distinct, seeing that P. melanogastra is less than 

 half the size of C. scopidatus and has a median pale stripe on the 

 carapace. And lastly from Simon's species O. erythrochelis from 

 Laudaua (Bull. Soc. Zool. France, i. p. 222), which also has red 

 hairs on the base of the mandible, C. scopulatus may be recognized 

 by the absence of pale bands on the carapace and the presence of 

 the black field on the lower side of the abdomen. 



Ctenits auricularis and C. capulinus of Karsch, from Chiuchoxo, 

 also seem to differ in colour from C. scopulatus, as well as from 

 C. occidentalis and C. Mnqsleyi (see Zeits. gesammt. Naturw. lii. 

 pp. 347-348, 1879). 



Ca?ENUS EiYULATUs, sp. u. (Plate LVII. figs. 26, 26 a.) 



5 . Colour. Carapace covered with blackish or olive-brown hairs, 

 with a median pale golden stripe, and a broad irregular interrupted 

 submarginal band extending from the sides of the clypeus to the 

 posterior boi'der ; upperside of abdomen ornamented with a median 

 golden-yellow or greyish band, narrow in front and indented at 

 the sides with four pairs of large black spots ; sides of abdomen 

 blackish, mottled with yellow or grey spots ; on the lower side the 

 pale spots are arranged in definite longitudinal posteriorly con- 

 verging lines : sternum, coxae, and lower side of legs uniformly 

 deep brown ; upperside of legs varied, especially on the femora, 

 with golden-yellow bands, the rest of the segments tinted with 

 yellow ; palpi uniformly dull brown ; mandibles black in front, 

 without bright coloured base. 



Carapace slightly elevated above behind the fovea, as long as 

 patella -|- tibia of 3rd leg, as tibia of 1st, and a little longer than 

 protarsus of 1st and than tibia of 4th, about four fifths of the 

 protarsus of the 4th ; ocular quadrangle more narrowed iu front 

 than iu C. scopulatus, its eyes relatively larger, the anterior 

 separated by a space which about equals the radius. 



Legs 4, 1, 2, 3; patella -f tibia of 4th a little less than of 1st
