Chelippdes une(|ual, the rij,'lit much the ]ar<,'er, about 11 mm. 

 in leiii,'th. Merus joint tri<,'oiiuH, its j^reater diameter nearly 

 equal to its length ; sur- 

 faces smooth ; inner and 

 inferior boi'ders minutely 

 spinulose ; superior border 

 with a series of scale-like 

 projections, the broadest 

 ■of which is situated im- 

 mediately posterior to a 

 subterminal transverse Eight Chelipkde ^ 6. 



groove. Fig. 13a. 



Carpus compressed, wider distally than long, and equal in 

 length to the merus ; inner surface deeply excavated and adapted 

 to the inner base of the palm ; outer surface covered with round 

 flat scales, of which some are in contact at the base and at the 

 sides. Upper and lower borders rounded, bounded on their 

 ■external aspect by faint ridges, that on the upper being the most 

 distinct ; both are invested with round flat scales, which are 

 rather oblique and raised at their apices ; the upper and lower 

 distal extremities terminate in an angular tooth. Hand com- 

 pressed, slightly convex, its depth equal to four-fifths of the almost 

 straight, rounded lower border ; the latter has on its external 

 aspect a faint minutely granular ridge, bounded above by a 

 narrow smooth groove, which extends from the lower point of 

 articulation to the tip of the finger. 



Upper border equal in length to the mobile finger, somewhat 

 acute proximally, and clothed throughout with scales, similar to 

 but smaller and less distinct than those on the carpal border. 



Lower border, fingers and both surfaces of the palm minutely 

 granulose and slightly setose. Fingers acute, calcareous and 

 crossed at the tips, with a narrow hiatus in the pi'oximal half 

 when closed ; inner edge of each with four distinct denticles and 

 two smaller near their bases ; a few stiff setfe arise from deepish 

 pits, and alternate with the teeth on the external edge of the 

 lower finger. 



Upper finger angular at the base internally ; outer and superior 

 surface rounded. 



Left chelipede 9 mm. long ; meral and carpal joints similar to 

 but more slender than those of the right. Hand elongate, smaller 

 than the carpus ; surfaces of palm 

 granulose ; lower border straight, 

 with a faint longitudinal ridge. 



Fingers slender, longer than the 

 palm, meeting along their finely 

 denticulated edges when closed ; upper border with a slight 

 granular ridge.
