restricted to species having this cristate character, as was done by De 

 Haan, but excluding such of De Haan's species as have not spoon- 

 shaped fingers. 



ZOZYMUS GEMMULA. 



Carapax nudus, nan granulatus, nitidus, antice* bene areolatus, areolis 

 paulo monticulosis, 1 M, 2M, discretis, 2 M subdivisd, fronte fere recto, 

 emarginato, margine antero-laterali tenui, leviter k-lobato, lobis tribus 

 posticis fere cequis. Pedes antici cequi, non carinati, manu carpoque 

 tuber culatis, tuberculis cum granulis acervatis wistriwAis ; manu extus 

 partim seriatim granulatd. Pedes 8 postici bene carinati, carind 

 articulorum Stii <iti prope apicem profunde incisd, tarso sparsim 

 hirsute. 



Carapax naked, not granulate, shining, anteriorly distinctly areolate, 

 areolets a little monticulose, 1M, 2M, distinct, 2M subdivided; 

 front nearly straight, emarginate, antero-lateral margin thin, faintly 

 four-lobed, three posterior lobes nearly equal. Anterior feet equal, 

 not carinate, hand and carpus tuberculate, tubercles made of aggre- 

 gated granules, outer surface of hand in part seriate with granules. 

 Eight posterior feet neatly carinate, carina of third and fourth 

 joints near apex profoundly incised; tarsus sparsely hirsute.

 diameters; b, front view of part of front, showing part of base of outer 

 antennas; c, outer view of right hand; d, posterior leg. 



Shores of a small island off the principal harbour of Sooloo. 



Length of carapax, 2-6 lines; greatest breadth, 3 - 9 lines; ratio of 

 length to breadth, 1 : 1-5. The areolets are somewhat marked with inter- 

 rupted cross lines, sometimes crenulate, and in some parts of the antero- 

 lateral the surface consists of low points. The lobes of the antero- 

 lateral margin are separated by a minute fissure, and are but slightly 

 prominent. Between the beaded tubercles of the hands and carpus 

 there is a slight imperfect velvety appearance. The third joint of the 

 posterior legs is naked, except two or three hairs at apex, and the 

 following joint is nearly the same; the fifth has some short hairs
