266 ME. C. J. WITH ON SOUTH-AMEEICAN CHELIPBRIN"^ 



Colour.— Th.e palps are dark brown, and so is the cephalothorax, while the abdominal 

 sclorites, placed within white skin, are light brown.

Female. 



Antennoe (PI. XXX. fig. 14 a). — The galea is a little longer and extends in a slight 

 degree beyond the terminal hau-. 



Palps (PL XXX. figs. 14 l-c). — The palps are only in a very slight degree different; 

 the ventral outline of the tibia is slightly and the dorsal fairly distinctly produced 

 (fig. 14 c); the hand is only 1*4 as long as wide and scarcely 1-1 as long as deep, 

 scarcely 1*3 deeper than wide. Of " spots" at least three are found at the base of the 

 movable finger anteriorly. 



Coxce (PI. XXX. fig. 14 cl). — The fourth pair are distinctly different from the 

 corresponding pair of the male, being as wide basally as terminally, and with the 

 inner margin separated from the hinder by a distinct obtuse angle and much longer ; 

 the whole coxa trapezoidal. 



Legs (PI. XXX. figs. 14 e-f). — The legs are perhaps a trifle less slender. 



Colour. — Body and palps a little lighter. 



Measurements. — Cephalothorax 0-989 (0-805) ; abdomen 4-25 (1-75) mm. 



Palps: trochanter 0-506 (0-345) ; femur 0-782 (0-391); tibia 0-805 (0-414); hand 

 0-828 (0-598), depth 0-782 ; finger 0-690 mm. 



Leg I.: femur 0-532 (0-236), trochantin 0-099 (0-228); tibia 0-380 (0-167); tarsus 

 0-350 (0-122) mm. 



Leg IV. : femur 0-810 (0-368) ; tibia 0-616 (0-220) ; tarsus 0-433 (0-160) mm. 



Material &c. — Of this species I have examined a female collected in Caracas by 

 Mr. Stroll and a male collected at Los Tejas (Caracas) by Dr. Meinert. Balzan's 

 specimen is from Venezuela. 



EemarJcs. — The insignificant differences found between Balzan's description and my 

 specimens are scarcely worth recording, except that he writes " Digiti . . . manu multo 

 breviores." This species may easily be distinguished from all other species known to 

 me by the curious palps, especially the excessively deep chela. In these, as well in 

 other respects, it shows a certain similarity to Ch. bicolor Balz., from which it, however, 

 differs by colour and shape of coxee and legs.
