 d. Carapace transversely suboval. 



e. Carapace with small, red, bead granules showing in the

ee. Carapace without bead granules showing in the 



pubescence: humilis.) 6

deep, not concealed by the pubescence, 

 e. Merus of ambulatory legs sharply cristate above: 



cristipesA 

 ee. Merus of ambulatory legs not cristate above: 



spongiosus.* 



bb. Carapace more or less hairy ; when covered with a short, close 

 pubescence, it is mixed with long hairs. 

 c. Larger palm more than half smooth and bare, at least in 



male, 

 d. Infero-distal portion of outer surface of smaller palm 



bare and, in male, smooth: flssifrons. 



dd. Outer surface of smaller palm rough all over and more 



or less hairy. 



e. Last three antero-lateral teeth armed with long, slender 



spines. A similar but larger projection at inner angle 



of wrist : spinicarpus.* 



ee. Antero-lateral projections dentiform, the last three 



armed with short spinules. Larger wrist with an 



acute, conical tubercle at inner angle: tantalus.* 



cc. Larger palm either partially smooth and bare on not more 



than half its outer surface, or rough all over. 

 d. Antero-lateral projections dentiform or lobiform, not 



spine-tipped. 



e. Palms and fingers finely granulate except on the short, 

 light brown, finger-tips. Chelipeds, legs and anterior 

 carapace ornamented with fringes of long and very 

 fine soft hair: digitalis** 



ee. Palms tuberculate. Fingers not granulate beyond their 

 basal portions, and nearly all brown. Hairs coarser 

 than in: digitalis, 



f. Carapace half smooth and bare. Fringes of long hair

5 The name humilis was suggested as an alternative by Miers (Crust. 

 "Alert," 188i, p. 221, pi. xxi., fig. B) for specimens which he doubtfully 

 labels P. lanatus Latreille. Latreille, however, in concluding his brief 

 description (Encye. Meth., Entom., x., 1825, p. 125) compares lanatus 

 with vespertilio, as follows : " Un pen, plus grand que le precedent, avec 

 les set-res e"paisses et g raveleuses ; d'ailleurs presque semblable. Vari6t6 

 peu,t-3tre du male de cette espece." This indicates a much closer re- 

 semblance of lanatus to vespertilio than one would ascribe to the trim 

 looking species figured by Miers, Inc. cit. I have, therefore, used the 

 name Innnilis for his species.
