and. between the inner angle and the articulation with the palm there 

 is again a row of granules. The chela in my specimen are equal in 

 size; according to de Man they are somewhat unequal, the left being 

 the larger. Both in the female of de Man as in my male specimen 

 the chela is scarcely twice as long as high, but, whereas in the female 

 the fingers are nearly as long as the palm, the mobile finger of the 

 male is distinctly shorter, and apparently more strongly curved (cf. 

 de Man's f. 6 and my f. 3 a and 3&); the palm is much inflated, 

 convex at both surfaces, minutely punctate and rounded at upper and 

 under border, the basal half of the upper border is marked with 

 a row of minute granules ; in the middle of the inner surface there 

 is a longitudinal row of granules and, above it, a group of finer gra- 

 nules (f. 36), which granulation seems to be less pronounced in the 

 female ; at the outer surface of the palm (f. Sa) there is a conspicuous row 

 of granules close to and parallel with the under border, this row is 

 continued till the tip of the immovable finger, which latter is in the 

 same level with the under border of the palm and not curved down- 

 ward ; the fingers are short, gaping at the base, excavated at the tip ; 

 the cutting margin of the immobile finger is armed with three teeth, 

 two of which are large, the third (distal) tooth is very small ; the 

 mobile finger has three or four small teeth in the basal half, followed 

 by two very small ones, and finally a large tooth at the end, immedi- 

 ately before the horny margin of the tip. All these teeth are again 

 chalky-white. 



With regard to the walking legs, there is some diffidence between de 

 Man's figure of the female and my (male) specimen. Firstly I have not 

 observed the peculiar blotted appearance of these legs as depicted by 

 de Man, though this character may have disappeared, but especially 

 the shape of the meropodites is rather different: instead of the 

 rather thick, inflated shape of these joints as figured by de Man (I.e., 

 pi. 10, f. 4), they are parallel-sided, with straight anterior and posterior 

 margin; there is a sharp subdistal tooth at the anterior margin, and 

 this tooth is even present in the case of the posterior legs, though it 

 is here very small; in the female it seems to be wanting at these 

 legs. The posterior margin of all the meropodites show again, at the 

 upper border, the spines, characteristic of the genus, and they are 

 more developed in the present species than in its congeners: near the 

 distal end there are on each meropodite two or more sharp, acute, 

 depressed teeth, diminishing rapidly in size distally; only in the first 

 pair of legs there are some sharp granules following the acute subdistal 

 tooth; in the hind legs, again, the under posterior margin of the
