238 ME. 0. J. WITH ON SOUTH-AMERICAN CHELIFERIN.E 



femur of the fourth pair of legs is 2"7 as long as deep, almost I'o as long as tibia, and 

 2 as low as tarsus long ; the latter is only a trifle shorter than the tibia. Legs as a 

 whole of less slender appearance than those of Ch. rufus Balz. {cf. figs. 3 c-e). 



Colour. — Palps and cephalothorax reddish brown with darker transverse grooves, 

 and abdominal tergites paler brown. 



Measurements. — Cephalothorax 0-620 {0-575) ; abdomen 1-265 (0-805) ram. 



Palps: trochanter 0-285 (0-161); femur 0-598 (0-175); tibia 0-560 (0-195); 

 hand 0-506 (0-240), depth 0-225 ; finger 0-460 mm. 



Leg I.: femur 0-395 (0-137), trochantin 0-110 (0-152); tibia 0-251 (0-084); 

 tarsus 0-258 (0-061) mm. 



Leg IV.: femur 0-441 (0-162); tibia 0-334 (0-107); tarsus 0-327 (0-068) mm. 



Material. — I have examined two males, viz., one of Mr. Ellingsen's original 

 specimens and one collected by Dr. F. Meinert at La Moka in the month of August. 

 The species has also been recorded from Paraguay, Venezuela, Brazil, and Ecuador. 



Variation. — A smaller and paler specimen in the British Museum showed a few 

 features worth recording. The seventh sternite possessed only a single circular area, 

 somewhat smaller than that of the following segment, instead of two. The immovable 

 finger had posteriorly four spots instead of three, and the movable two instead of three- 

 As no other difi'erences were observed, this animal is most naturally referred to 

 Ch. canestrinii Balz. The label mounted with the specimen reads " Balthazar 

 (Windward), Island of Grenada, 250 feet, Aug. 8. Open place under piles of 

 rotting weeds." 



Bemarks. — This species is easily distinguished from the two preceding as well as 

 from Ch. ])roximus Ell. by the less slender femur and the longer hand ; from the latter 

 species also by the much shorter fingers. The male is easily distinguished from all 

 species examined by me by the structure of the sternal areas.

Male. 



Ge])halothorax. — Two rather indistinct eyes, or, perhaps more correctly, ocular spots 

 only. Cephalothorax is distinctly longer than wide, almost as wide in the anterior 

 third as behind, but beyond distinctly attenuated. The two transverse grooves are 

 generally rather indistinct ; the anterior is almost straight in the middle, but the 

 posterior is slightly curved forwards. Distinct and rather pointed granules are 

 found everywhere except on the white spot, which covers the median portion of 

 the second tergite ; short, distinctly clavate hairs are found in numbers.
