thickens distally, with the inner, outer and upper surfaces granulose, 

 the upper surface with two longitudinal rows of spinules ; the palm is 

 as long as the carpus, a carina of spinose granules extending obliquely 

 from the proximal margin of the propodal finger back to the base of 

 the palm, forming a prominent ridge, the outer surface of the palm, 

 especially the lower part, is very roughly granulose. The propodal 

 finger of the smaller claw is triangular, as long as the palm, the tip 

 corneous and the cutting edge set with truncate, corneous teeth ; the 

 hinged finger is much slenderer, with the tip also corneous; there is 

 a narrow, button-hole-shaped gape between the fingers. 



The first and second ambulatories are subequal to each other, but 

 those of the right side are distinctly longer than their mates on the 

 left side; the first right ambulatory has the merus 18.5 mm. long, 

 strongly compressed laterally ; the carpus is 12.5 mm. long ; the dactyl 

 is 20 mm. long; the propodus and dactyl are stocky but compressed 

 laterally, the upper outer surface granulose and set with numerous 

 stiff setae; the dactyl is thick, sickle-shaped, tapering and is armed 

 on its distal half with numerous horny spines which are set in ap- 

 proximately two rows along the inner and outer lateral margins; the 

 tip is also set with a horny nail. The first left dactyl is similar to the 

 right one, except that it has the following measurements: merus, 14 

 mm. long; carpus, 11.5 mm. long; propodus, 12.5 mm. long; dactyl, 

 17 mm. long. 



The fourth legs are very short and stocky and strong ; the propodus 

 is short, about as wide as long, with the lower lateral margin convex, 

 the lower anterolateral angle forming a blunt tooth ; a patch of horny 

 scales on the distal half of the lower margin ; the dactyl is short, thick, 

 curved, its horny apex applied to and extending beyond the tooth-like 

 process of the propodus, creating the superficial appearance of a 

 chela. 



The fifth legs are small, arched beside the body, the entire distal 

 part of the palm covered with corneous squamae ; the dactyl is very 

 small, short, with the distal margin bluntly rounded and fitting into 

 the spatulate propodal finger, both with the margins set with short, 

 corneous spinules ; the dactyl with a thick brush of very long setae.
