296 ME. C. J. WITH ON" SOUTH-AMEEICAN CHELIFEEINiE 



Measurements. — Cephalothorax 0'805 (0'690) ; abdomen 2'530 (1"035) mm. 



Palps: trochanter 0-460 (0-276); femur 0-759 (0-355); tibia 0-782 (0-391); hand 

 0-851 (0-510), depth 0-460; finger 0-575 mm. 



Leg I.: femur 0-547 (0-182), trochantin 0-091 (0-190); tibia 0-433 (0-118); tarsus 

 0-357 (0-079) mm. 



Leg IV.: femur 0-725 (0-296); tibia 0-623 (0-167); tarsus 0-418 (0-114) mm. 



Variation. — A single male from the same locality as the typical one differed by the 

 very prominent basal elevation of the tibia. 



Material. — I have examined four specimens (2 c? and 2 $ ) from Argentine, 2 speci- 

 mens ( <S and ? 1), collected by Dr. W. Sorensen under bark at Kiacho dell' Oro, 

 and two others ( d and $ X), sifted by Dr. Meinert, at La Moka, in the month of 

 August. 



Bemarks. — This species seems to be nearly related to Ch. ovatus Balz., but differs 

 by its much smaller size, by the tibia of the palps, which is less strongly convex, and by 

 the hand, which is only about 1-5 not 1-8 as long as the fingers, which are distinctly 

 longer, not shorter, than hand is wide. From Ch. argentinus Thor. and other species, 

 in which the movable finger of the palps has no spots anteriorly, it differs by less 

 slender palps. From Ch. co7mnunis Balz., as well as from Ch. intermedius Balz., it 

 differs by the absence of spots on the movable finger ; from the former of these also 

 by the tibia, which has a short stalk and is only twice or less as long as broad, 

 and from the latter by the tibia of the male, which is not produced anteriorly and 

 dorsally.

This large species may perhaps most easily be recognised by the following structures : 

 the galea is moderately branched ; the femur of the palps is about 2-3 as long as wide ; 

 the tibia, which has both lateral outlines equally and distinctly convex, is twice as long 

 as wide, and 1-3 narrower than the hand, which is as wide as the finger is long and 

 1-8 longer. — Venezuela.

Cephalothorax smooth and polished, with single transverse stripe; the galea is well 

 branched ; the tihia is rather suddenly convex anteriorly and shorter than hand, which 

 is about as long as finger. A re-examination of the typical species is necessary, as 

 the description is too imperfect to be of any value. — Brazil.
