are moderately convex, while the ventral is almost straight. Both fingers possess 

 anteriorly two accessory teeth near to the end, and posteriorly a few distally. The 

 immovable finger is anteriorly adorned with about nine basal ^^ spots " densely crowded 

 {cf. text-fig. 70) and has posteriorly three between the three basally placed tactile hairs ; 

 while the movable has only two spots, placed basally. 



CoiC(K. — The second pair are only slightly narrower at the base ; the fourth, 

 trapezoidal pair, are much longer than wide, scarcely widened out towards the 

 extremity, the inner margin is fairly well distinguished from the slightly concave 

 and much longer hinder margin. 



Legs. — The proximal joints are slightly gramilar. The fairly long hairs are slightly 

 claTate or obtuse dorsally ; those of the ventral side are pointed ; the tarsal " tactile " 

 hair, which is as long as its distance from the tip, is two-thirds removed from the 

 base. The hairs are moderately long and slender, and the trochantin of the first pair 

 of legs is scarcely deeper than the distal femoral part, while its tibia is as long as the 

 tarsus, which is 3-7 as long as deep. The fenmr of the fourth pair of legs is 2-2 as 

 long as deep, 1'2 as long as the tibia, and 1-6 lower than the tarsus is long. 



Colour. — The palps, the head, and first thoracic tergite as well as a semicircular 

 spot of the second, and the tergal sclerites are yellowish brown, while the rest of the 

 thoracic tergite and the interstitial parts are yellowish or white. 



Measurements. — Cephalothorax 0-529 (0-437) ; abdomen 1-150 (0-690) mm. 



Palps: trochanter 0-228 (0-137); femur 0-395 (0-179); tibia 0-410 (0-190) ; hand 

 0-438 (0-266), depth 0-296; finger 0-360 mm. 



Leg I.: femur 0-251 (0-106), trochantin 0-053 (0-106); tibia 0-182 (0-072); 

 tarsus 0-182 (0-049) mm. 



Leg IV. : femur 0-319 (0-144) ; tibia 0-274 (0-084); tarsus 0-228 (0-061) mm. 



Material. — E. Simon collected a single female in St. Vincent, whilst Ellingsen's 

 specimen was from Para. 



Bemarks. — I have referred this specimen to Ch. nitidimanus Ell., in spite of its 

 small size, lighter colour, less strongly convex outlines of tibia and hand, and shorter 

 fingers. By its smooth hand it is distinguished from at least most South-American 

 species.

Cephalothorax. — Ocular spots (]) rather indistinct; as their chitin is transparent, 

 without granulation and slightly convex, they may perhaps be designated real eyes. 

 The cephalothorax, which is somewhat longer than wide, has two transverse grooves, 

 a wide and shallow anterior one almost straight and very prominent, and a posterior 

 distinctly curved forwards in the middle and less prominent. The integument is
