29S ME. C. J. WITH ON SO DTH- AMEBIC AN CHELIFEEIN^ 



o-ape when closed and are scarcely 1"1 as long as the hand is wide ; the hand is 

 moderately convex anteriorly and dorsally, but only slightly so posteriorly and ventrally. 

 Anteriorly the fingers bear only a few accessory teeth distally (fig. 27 c) and posteriorly 

 about ten. The immovable finger has anteriorly from 11-18 "spots" arranged some- 

 what difi"ereutly in the various specimens, in two groups {cf. rig. 27 c), and the movable 

 finger has from three to five spots in the basal half; posteriorly the spots in the single 

 specimen examined are placed as shown in figure (fig. 27 d). 



Coxce. — The fourth pair are somewhat triangular, as the hinder and inner margins, 

 which are of about equal length, are not well distinguished from each other, the angle 

 between being very obtuse. 



Legs. — The hairs are moderately long. The legs are rather short and clumsy : the 

 tibia of the first pair of legs is 1'2 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, IT longer than the 

 tibia, and 1"6 lower than the tarsus is long. 



Colour. — The palps are dark reddish brown ; the cephalothorax and the abdomen 

 brownish. 



Measurements. — Cephalothorax 0-805 (0-735); abdomen 2-530 (0-966) ram. 



Palps: trochanter 0-395 (0-265); femur 0-690 (0-368); tibia 0-725 (0-391); hand 

 0-820 (0-529), depth 0-515; finger 0-555 mm. 



LegL: femur 0-471 (0-175), trochantin 0-084 (0-179); tibia 0-357 (0-114); tarsus 

 0-304 (0-076) mm. 



Leg IV.: femur 0-588 (0-258) ; tibia 0-532 (0-144); tarsus 0-365 (0-095) ram. 



Variation. — The specimen which Mr. Ellingseu kindly sent me for examination 

 differed by the less slender abdomen and more powerful palps, but scarcely in any 

 character of importance. 



Female. 



Cephalothorax &c. — The second transverse stripe is obsolete ; the abdomen in the 

 specimen examined is rather clumsy, being dilated with eggs. The arrangement of the 

 hairs is in the main as in Ch. similis Balz. The galea of the antennae is almost 

 exactly similar to Balzan's figure 8 a, pi. 9. 



Palps. — The trochanter has the dorsal protuberance somewhat lower and more 

 rounded and is 0-7 as long as wide. The femur, which is comparatively more long 

 and slender, viz. 2-1 as long as wide, is posteriorly as well as dorsally less abruptly convex. 

 The tiMa, which is about 1-9 as long as wide, is anteriorly less strongly convex, and has 

 posteriorly the condylus as well as the basal elevation more prominent. The chela, 

 which is 2-7 as long as wide, is only I'l broader than the trochanter is long ; the hand 

 is 1'7 longer than deep and 1-1 wider than deep. 



Coxm. — The fourth pair are trapezoidal, at least as long as broad, with the inner 

 margin well separated from the much shorter hinder one.
