PODOCHELA SPIN1FRON8, new species. 



Carapace spinnliferous. Cardiac region witli an erect si)iiie; gastric 

 region witli a spine directed forward and a spiny tubercle in front of 

 tbe latter. Tlie rostrum is long and sliarp, arched, with a median 

 spiniferous crest. Orbits with an erect si)iniilifei()us crest, bearing- two 

 slender spines. The antennal Joint is largely visible from above and 

 carries a spine at its anterior angle. There is an oblong laminiform 

 ])ostorbital tooth and behind and below it a tlat triangular tooth; these 

 two teeth correspond in position to the small tubercles present in 

 7*. gracilipes and other species. The hepatic spine is narrow, flattened 

 and obtuse, and the pterygostomian region has a similar spine. The 

 buccal cavity is conspicuously crested at its anterior angle. The 

 antennal joint has a cristiform inner margin and an angular ridge on 

 its posterior half. The sternal crests in the male are flat, tuberculous, 

 ami separated by deep sulci. The coxal Joints of the legs bear crests 

 similar to those in P. IdDieUigera, but less prominent. The antericu' part 

 of the sternum in the male is pubescent, and has two stout spines in 

 front of the abdomen, Avhich project downwaid and forward. The 

 first segment of the abdomen bears a spiniform tubercle at its distal 

 extremity. The chelii)eds i!i both sexes are slender, hirsute and 

 spinnliferous; fingers with i)rehensile edges in contact. Ambulatory 

 legs very hairy, except the slentler yellow horny tips of the dactyli.
