Leg I. : femur 0-585 (0-185), trochantin 0-106 (0-198) ; tibia 0-464 (0-129) ; tarsus 

 0-426 (0-091) mm. 



Leg IV. : femur 0-760 (0-296) ; tibia 0-646 (0-175) ; tarsus 0-486 (0-114) mm. 



Female. 



Cephalothorax. — The posterior stripe is obsolete or very indistinct. 



Pal^js (PL XXXI. figs. 28 d-g). — The dorsal protuberance of the trochanter is much 

 lower and more rounded (fig. 28 e). The /emw, which is distinctly attenuated towards 

 the extremity, is 2-1 as long as wide ; it is less abruptly convex posteriorly as well as 

 dorsally. The tibia has the stalk less slender than in the male, and the dorsal and 

 ventral outlines are less curved. The chela is less slender, being scarcely three times 

 as long as wide ; the hand is only 1-6 as long as wide, only a trifie deeper than wide, 

 and 1-4 as long as the fingers, which are 1-2 as long as the hand is wide. The 

 variations in number and arrangement of accessory teeth and " spots" which are 

 observed when comparing the figures and previous description, are scarcely greater 

 between males and females than between difi'erent specimens of the same sex [cf. 

 figs. 2^f-g). 



Cowce. — The fourth pair are very similar to those of the male, the inner margin 

 being only about twice as long as the hinder. 



Legs. — The tarsus of the first pair is only four times as long as deep. 



Measurements. — Cephalothorax 0-805 (0*690) ; abdomen 3-2 (1"61) mm. 



Palps: trochanter 0-391 (0-253); femur 0-690 (0-322); tibia 0-690 (0-335) ; hand 

 0-713 (0-437), depth 0-460 ; finger 0-529 mm. 



Leg I. : femur 0-441 (0-144), trochantin 0-076 (0-160) ; tibia 0-350 (0-099) ; tarsus 

 0-319 (0-076) mm. 



Leg IV. : femur 0-638 (0-236); tibia 0-509 (0-140); tarsus 0-388 (0-091) mm. 



Variation. — d . Several males collected by Dr. Meinert in La Moka difier from the 

 described one from Bahia by the more slender palps, viz. the femur, which is 2*1 as long 

 as wide, is less abruptly convex posteriorly as well as dorsally ; the tibia is 2*2 as long 

 as wide ; the other joints also diff'er in a slight degree, but with regard to these I refer 

 to the measurements. The legs are in a remarkable degree more slender, the tarsus of 

 tlie first pair being at least five times as long as deep, and the femur of the fourth pair 

 being almost three times as long as deep and 1*7 lower than the tarsus is long. While 

 almost all the hairs were missing in the described male, this well-preserved specimen 

 has them well- developed and their number appeared to be greater, viz. from 14-18 

 along the hindmost margin in addition to two lateral and a single median one in front 

 of the row on each side ; a few of the hairs along the margin are sometimes placed a 

 little in front of it ; this is especially the case with a very long and slender hair, which 

 in the hindmost segments becomes a " tactile " hair exactly as in Ch. similis Balz., to
