286 ME. C. J. WITH ON SOUTH- AMEBIC AN CHELIPEEIN^ 



while posteriorly the immovable finger has four and the movable only one " spot " 

 {cf. figs. 23 h-c). 



Coxce. — The coxse are distinctly diff'erent from those of Chelifer hicolor Balz. ; the 

 second and the third pair are both widened out towards the end, especially the latter, 

 as the former is much broader than this at the base and not suddenly narrower ; the 

 fourth pair are almost wider basally than distally, quadrangular, with the inner margin 

 well separated from, and shorter than, the hinder one. 



Legs (Pis, XXX.-XXXI. figs. 23 d-e). — The proximal joints are completely smooth ; 

 the fairly long or long hairs are pointed and completely simple or almost so ; dorsally 

 just behind the tip of the femur a very long and slender hair is observed in the fourth 

 pair of legs ; a similar hair, but even longer, is placed exactly in the same position in 

 the tibia. The tarsus IV. has the " tactile " hair placed nearer to the base than to 

 the tip, and it is a little longer than the latter distance [cf. fig. 23 e) ; between the 

 "tactile" hair and the base another vnde articular cavity is observed {cf. above). 

 The legs are very long and slender, and the trochantin of the first pair of legs is much 

 deeper than the femur proper, while its tarsus, which is about five times as long as 

 deep, is I'l longer than the tibia. The fenmr of the fourth pair of legs is 3-2 as long 

 as deep, 1-1 as long as tibia, and 2-3 lower than the tarsus is long. 



Colour. — The palps, cephalothorax, and tergal sclerites are light brown, but of 

 somewhat difi'erent shades. 



Measurements. — Cephalothorax 0-552 (0-437) ; abdomen 1-541 (0-897) mm. 



Palps: trochanter 0-266 (0-175) ; femur 0-410 (0-190); tibia 0-426 (0-198); hand 

 0-433 (0-266), depth 0-266; finger 0-385 mm. 



Leg I.: femur 0-296 (0-084), trochantin 0-076 (0-099); tibia 0'228 (0-068); 

 tarsus 0-251 (0-050) mm. 



Leg IV.: femur 0-380 (0-118); tibia 0-342 (0-084); tarsus 0-266 (0-061) mm. 



Material. — Of this species I have examined a single female with a bundle of eggs, 

 collected by Mr. H. H. Smith in the month of March, in a half-shady place in a 

 mixture of earth and old manure, at Balthazar (Windward), Island of Grenada. 



Eemarks. — This species is, as far as can be judged from Balzan's very imperfect 

 description, in most respects similar to Ch. brevifemoratus Balz. (1890, lo, pp. 420- 

 421, tav. xiv. figs. 7-7 c) ; but as it has no trace of ocular spots or second transverse 

 groove, as it has smooth tergal sclerites with long and pointed hair instead of 

 " setole .... corte, troncate all' apice et dentate," and as the palps are not granular 

 all over, without " peli quasi clavati," and the inner outline of the tibia is moderately, 

 not strongly, convex, I prefer to establish a new species, especially taking into 

 consideration that the above-described form is at least not identical with one from 

 Ecuador with " de polls claviformes," which Ellingsen (15. pp. 156-158) has referred 

 to Ch. brevifemoratus Balz. It differs from Ch. michaelsenii Sim. by the attenuated 

 femur of the palps.
