Palps (PI. XXX. fig. lb d). — The proximal joints of the palps scarcely differ, but 

 the chela is distinctly different, being 2-6 as long as wide ; the hand, which is 1*5 as 

 long as wide and 1"4 as long as deep, is only 1-1 deeper than broad and 1'5 longer 

 than the fingers, which are somewhat longer than the hand is broad ; the dorsal outline 

 is distinctly convex, but far from being semicircular. The number of accessory teeth 

 seems to be somewhat smaller ; the difference in arrangement of spots is not greater 

 than that between different specimens of the male. 



CoxcB (PI. XXX. fig. 15 e). — The fourth pair are distinctly wider, with the inner 

 margin only a little shorter than the hinder. 



Legs. — The legs seem to be somewhat longer and more slender, the femur of the 

 fourth pair being, for instance, 2-6 as long as deep and 1*6 lower than tarsus is long ; 

 the tibia of the fourth pair has the usual shape and is four times as long as deep. 



Colour. — The palps and the cephalothorax are somewhat lighter and so are the 

 brown areas on the abdominal tergites, which are somewhat larger ; the median and 

 lateral dark spots are not only fused in front but also behind, so that a dark area with 

 a white spot in the middle is established. 



Measurements. — Cephalothorax 0-713 (0"736); abdomen 2*875 (1*265) mm. 



Palps : trochanter 0*368 (0*240) ; femur 0-713 (0*310) ; tibia 0*736 (0*335) ; hand 

 0*782 (0*506), depth 0*565; finger 0*529 mm. 



Leg I. : femur 0*456 (0*175), trochantin 0*084 (0*182) ; tibia 0*342 (0*118) ; tarsus 

 0*319 (0*080) mm 



Leg IV.: femur 0*631 (0*243); tibia 0*547 (0*137); tarsus 0*395 (0*104) mm. 



Material &c. — Dr. Meinert collected from 20/vi.-l/ix., 1891, numerous specimens 

 (5 c? , 10 ? ) of this pretty species in Venezuela, where it seems to live under the bark 

 of trees ; Dr. Meinert at least mentions localities where they have been collected under 

 bark, while it is not found amongst the numerous specimens which were captured by 

 sifting. A single male carried a small worm in its large chela. Balzan's specimens are 

 from Petare and Caracas. 



jRemarks. — This species is well characterised by its colour and deep chela.

Male. 



Cephalothorax. — Ocular spots very indistinct. The cephalothorax, which is distinctly 

 wider behind than it is long, has two fairly distinct transverse grooves, of which the 

 anterior is curved backwards and the posterior forwards in the middle. The integu- 

 ment all over is strongly and coarsely granular with rounded or pointed granules, and 

 provided with moderately long, distinctly clavate hairs. 



Abdomen. — The abdomen, which is only a little longer than wide, is flattened and of
