EEPORT ON THE ANOMURA. 47 



processes at the posterior part of the area. The surface of the gastric spine, as in the 

 case of all the other spines found on this species, is granulated. The cardiac area is convex 

 and moderately circumscribed, capped by four tubercular spines arranged as if at the 

 four angles of a square ; the groove which separates this region from the gastric area is 

 smooth and devoid of granulations. The branchial area possesses a prominent and acute 

 spine opposite the centi-e of the cardiac area, and towards the posterior border of the 

 carapace one or two tubercles. The cervical groove is represented on the surface of the 

 carapace by an irregular, sparingly granulated depression, at the anterior end of which 

 there is a smooth oval elevation. The external orbital spine arises internally to but in 

 line with the antero-lateral sjjine, the lateral border is armed with five or six spines, 

 two of which are situated in front of the cervical groove, while the two immediately 

 behind this are largest in size ; the second spine is curved forwards and inwards. 

 The posterior border possesses one or two tubercular spinules on each side and from four 

 to six small subcentral tubercles. 



The ocular peduncles are granulated above, and, as in the last species, terminate in a 

 small spine; the cornets are oblique and deeply pigmented. The second joint of the 

 antennular peduncle extends to a point opposite the end of the antennar peduncle ; the 

 first joint of the latter possesses a prominent and acute external spine, the second bears 

 one of much larger size with a secondary projection at its base ; the squame is quadri- 

 spinose, two of the spines being of small size. The merus of the external maxillipedes 

 is slightly granulated externally. The pterygostomial region bears a somewhat blunt 

 spine anteriorly. 



The chelipedes and ambulatory limbs are long, and as in the case of the carapace 

 covered with fine granulations, which are more numerously arranged on the upper surface. 

 The chelipedes are subequal in length, the right being stouter; the meral joint is 

 furnished with two prominent spines on its inner and distal border, and several are also 

 present on the carpus, the two posterior of these being of large size and curved ; the 

 propodus bears a double row of large tubercles on its outer surface, and a series of 

 tubercular spines on the upper border ; the fingers are each provided with three rounded 

 teeth and numerous tufts of hairs. The meral, carpal, and propodal joints of the 

 ambidatory limbs are bordered anteriorly by stout spiniform processes, of which one at 

 the distal end of the merus and carpus respectively is most prominent ; the posterior 

 border of the merus and propodus bears a somewhat smaller series ; the propodi are 

 moderately curved, tipped with dark corneous spines, and fringed inferiorly by a row of 

 horny spines. 



The abdominal plates are distinctly granulated ; the second segment bears two blunt 

 spines on a mesial elevation, and two subcentral tubercles on the posterior border ; the 

 penultimate segment bears a terminal projection on each side, and the telson is bi- 

 tuberculate.
