276 ME. 0. J. WITH ON SOUTH- AMEEICAN CHELIFEEEST^ 



trochanter is long ; the hand, which is a little longer, but 1'5 wider than the tibia, is 

 1'4 as long as wide, a little deeper than wide and 1*3 as long as fingers, which are a 

 little longer than hand deep, and do not gape when closed ; the lateral outline, as 

 well as the dorsal which is more suddenly produced, is distinctly convex, while the 

 ventral is only slightly so. Both fingers bear anteriorly two distal accessory teeth 

 [cf. fig. 18 e), while the immovable finger has posteriorly 9 teeth and the movable as 

 many as 12, placed from near the base to almost the tip {cf. fig. 18_/). The 

 immovable finger possesses anteriorly three " spots " behind the basal hair, six in the 

 area between the four " tactile " hairs, and four in a longitudinal row near to the 

 lower margin, while the movable finger has about eight in a longitudinal row from 

 the base to near tip (fig. 18 e) ; posteriorly the immovable finger has about ten and 

 the movable eight " spots " arranged as shown in fig. 18/". 



Coxce (PI. XXX. fig. 18 g). — The coxse are very similar to those of Ch. bicolor 

 Balz. {cf. fig. 15 e), the only difference being that the third pair are basally restricted, 

 and that these, as well as the second pair, show traces of an anterior blunt basal 

 process : the fourth pair are besides more slender. 



Legs. — The proximal joints are only very indistinctly granular. The hairs of the 

 dorsal surface are moderately long, and distinctly clavate in the fourth pair of legs, 

 but slightly clavate or obtuse in the first pair, while those of the ventral surface are 

 pointed and more or less simple. The tarsal '■'■tactiW hair, which is distinctly longer 

 than the distance to the tip, is three-fourths removed from the base. The legs are 

 fairly long and slender ; the trochantin of the first pair is much deeper than the femur 

 proper; the tibia is a little shorter than the tarsus, which is 4'5 as long as deep. The 

 femur of the fourth pair of legs is 2'7 as long as deep, 1*1 longer than the tibia, and 

 almost 1'9 lower than tarsus long. 



Colour. — The three proximal joints of the palps are yellowish brown with the basal 

 and terminal part lighter ; the chelse are dark brown, and so is the cephalothorax 

 with the exception of two white spots, which in the middle are separated by a median 

 quadrangular dark spot and laterally bounded by a narrow dark stripe. The tergal 

 sclerites of the abdomen are brownish, and the membranes between are yellowish. 



Measurements. — Cephalothorax 0'690 (0"690) ; abdomen 1-725 (1-495) mm. 



Palps: trochanter 0-335 (0-207); femur 0-598 (0-253); tibia 0-598 (0-285); 

 hand 0-621 (0-437), depth 0-437; finger 0-495 mm. 



Leg I. : femur 0-395 (0-132), trochantin 0-084 (0-140) ; tibia 0-296 (0-091) ; tarsus 

 0-312 (0-068) mm. 



Leg IV.: femur 0-532 (0-200) ; tibia 0-479 (0-114) ; tarsus 0-372 (0-080) mm. 



Material. — Of this pretty species I have examined a single female, collected by 

 Dr. Meinert in the month of January on a road " Old la Guayra (Caracas) " ; I have 

 named this species after Dr. Meinert, who collected such a number of these animals 

 in Venezuela.
