twice as long as the preceding member and 3, 5 -times as long as wide, showing its greatest 

 width just in the middle and equally narrowing to both extremities, the distal obliquely 

 truncate. Carpus 0,616 mm. long, but a litde longer than the ischium, 0,28 mm. thick at the 

 distal extremity, when measured in the plane of the merus, appearing about twice as long as 

 thick; the concave, distal extremity embraces the chela. Chela 1,12 mm. long, twice as long 

 as the ischium and hardly longer than the merus ; looked at in the plane of the merus, 

 the chela appears thickest near the proximal fourth part; the thickness here is one-fourth of 

 the length and it tapers regularly to the extremity of the fingers. Measured in the level of 

 the fingers, the chela appears a little higher, viz. 0,322 mm., appearing 3,5-times as long as 

 high, while the height of the palm is in proportion to its thickness as 23 : 20; fingers tapering, 

 a little shorter than the palm, the length of the chela being in proportion to the length of 

 the fingers as 16:7. The immobile finger and the dactylus carry each a very small, acute 

 and oblique tooth, a little farther distant from the tip than from the articulation, which teeth 

 are of equal size; one observes a larger conical tooth just near the tip of the immobile 

 finger, at the end of the cutting-edge, this tooth is subacute and twice as high as thick at 

 its base and there is still another, more acute and smaller tooth which is probably placed 

 between the other and the extremity of the finger. The dactylus, finally, bears also two teeth 

 near the tip, but these teeth are acute, directed obliquely forward, parallel with the acute tip 

 of the finger and are placed abreast ; they are smaller than the tip of the finger, but their 

 form and their size are the same, while they are somewhat smaller than the conical tooth of 

 the immobile finger and of the same size as the tooth between the latter and the tip. 



Merus of second legs in the male 3, 7 5 -times, in the adult female 5,75-times longer than 

 wide. Carpus, in the male, 1,31 -times, in the adult female 1,26-times as long as the merus; 

 in the male the carpus is 7,6-times, in the adult female 9-times as long as thick at its distal 

 e.xtremity, near the articulation of the chela. First segment of the carpus, in the male, 3,3-times 

 longer than thick distally and measuring two-thirds the sum of the four following; fourth 

 segment a little longer than the second and the third that are equal ; chela one-third longer 

 than the first segment, fingers but a little shorter than the palm. In the adult female the first 

 carpal segment is 4,5-times as long as thick distally and the sum of the four following segments 

 is 1,22-times as long as the first segment; the three following segments are equal, and the 

 chela is as long as the first segment, while the fingers are as in the male. 



Ischium of third legs with a movable spine near the base of the posterior margin and 

 with another less strong spine at the distal extremity of the upper margin. Merus unarmed, 

 propodus. in the male, with six small and feeble spinules, long 0,08 mm., and with a much 

 longer spine, long 0,16 mm., at the distal extremity, this spine half as long as the dactylus 

 and accompanied by a smaller one; in the adult female the propodus carries eight spinules, 

 long 0,06 — 0,14 mm., and the larger spinule at the far end measures 0,21 mm. The dactylus, 

 in the adult female just one-third of the propodus, in the male a little longer, is slender, 

 5-times as long as wide near the articulation and it bears at the distal third a small and 

 feeble, accessory hook; this ventral hook measures about one-fourth of the principal hook, 

 while its width at the base is only one-fourth that of the latter.
