posteriorly each possesses a few in the distal third ; the movable finger has only two 

 spots anteriorly near to the base, while the immovable finger has five anteriorly, of 

 which two are very large, two small (fig. 35 h)^ and one very large placed 

 posteriorly. 



Coxce. — The coxae are very similar to those of Ch. argentiniis Thor. {cf. text-fig. 75) ; 

 the fourth are trapezoidal, scarcely widened out towards the extremity, and with the 

 inner and hinder margins, between which is a distinct obtuse angle, of almost equal 

 length. 



Legs (PI. XXXI. figs. 35 c-d). — The hairs are rather short, with a long, slender, 

 compleely simple hair placed dorsally, somewhat beyond the middle of tibia IV., 

 as well as one tarsal, one-fourth removed from the base and as long as the distance to 

 the tip ; the terminal dorsal one of femur IV. was not observed, but a long, not 

 completely simple one is placed dorsally near the tip of the libia. The legs are rather 

 short and clumsy; the tibia of the first pair is I'l as long as the tarsus, which is four 

 times as long as deep; the femur of the fourth pair of legs is 2-3 as long as deep, 

 almost 1'2 as long as the tibia, and only 1"3 lower than the tarsus is long. The anterior 

 claw of the first pair of legs has a rather small median tooth, and the posterior has a 

 rather large triangular process (fig. 35 c), while the anterior claw {ci) of the fourth 

 pair of legs has practically no tooth and the posterior has a rather big, somewhat 

 triangular tooth {cf. fig. 35 d, ce). 



Colour. — The palps and cephalothorax are reddish brown ; and the tergal sclerites 

 are dark brown.

Material. — Of this species I have examined a single badly preserved female from 

 Uruguay (Keyserling Coll.). 



Remarks. — This species shows in the shape of the palps great similarity to Ch. ovatus 

 Balz. {cf. fig. 6, pi. 9, ii), but as it is much smaller, as the galea is much better 

 developed, and as Ba zan does not mention the presence of teeth in the claws, I do not 

 hesitate in establishing my specimen as a new species. In the shape of the claws this 

 species shows certainly greater similarity to Ch. cervus Balz. than to any other, but, 

 nevertheless, I am not convinced that the two are nearly related to each other 

 {cf. above).
