wide, has the anterior outline more distinctly convex. The femur, which is about 

 3-8 as long as wide, is less distinctly widened out towards the extremity. The tibia, 

 which is somewhat shorter and broader than the femur, has a short and fairly well- 

 defined stalk and is 3-2 as long as wide ; anteriorly it is very slightly convex, 

 and posteriorly beyond the short basal elevation almost straight. The chela is 

 3-1 as long as wide ; the hand, which is as wide as the trochanter is long, is 

 scarcely 1-1 shorter than the tibia, but 1-6 broader; it is 1-8 as long as wide, as 

 wide as deep, and 1-3 as long as fingers, which scarcely gape when closed; lateral 

 outlines moderately convex, with most raised part just beyond the stalk. The number 

 of " spots " anteriorly is as in the male, but posteriorly slightly differs, as seen in 

 fig. 6 d. 



Coxce. — The second and the third pair are less distinctly triangular, as the interior 

 margins are longer ; the fourth pair are quite dissimilar and distinctly quadrangular, 

 as the interior margin is well developed, scarcely shorter than the exterior and only 

 1'5 shorter than the posterior. 



Legs. — The granulation is better marked ; the proportions between the joints 

 differ in a slight degree, as the tibia of the first pair is scarcely I'l as long as 

 the tarsus, which is about 4*7 as long as deep, and femur IV. is only 2*4 as 

 long as deep. 



Colour. — The colour is sometimes fairly similar to that of the male, but with 

 white spots on the second thoracic tergite and white band on the abdomen less 

 prominent ; in other cases scarcely any difference whatever.

Leg IV.: femur 0-501 (0-205); tibia 0-410 (0-110) ; tarsus 0-342 (0-068) mm. 



Material 8fc. — Of this species I have examined a number of specimens, viz., 3 females 

 collected by Dr. W. Sorensen at Riacho dell' Oro, and 12 males and 3 females collected 

 by Dr. Er. Meinert in Venezuela, for instance, at Caracas under bark of Bombax in the 

 month of June, in rotten branches with termites, Los Trincheras, in the month of 

 November, La Moka, by sifting in August, and San Esteban. Previously it had been 

 recorded from Paraguay, Brazil, Venezuela, and Ecuador. 



Bemarhs. — It is not without hesitation that the species described is referred 

 to Ch. longichelifer Balz., for Balzan writes in his description " II trocantere e eguale 

 nei due sessi, multo piu lungo che largo," while the difference in the length of 

 the trochanter is very marked in the two sexes ; but as Balzan's own figures 

 (ii. figs. 26, d ? ) show some difference, I think that Balzan's original specimens 

 must be examined before settling the question definitively. Other variations found in
