THE SPECIES OF AEGLA — SCHMITT 479 



Large hand short, stout, inflated, and smooth appearing; short 

 fingers gaping, without the usual characteristic lobular tooth of an

 chela) ; no lobe or trace of one on outer margin of movable finger 

 near base; no trace of a ridge, however faint, on upper surface of 

 palm. No palmar crest, dorsal margin of palm broad, thick and

low and more or less obsolescent (it may be faintl}^ traced for about 

 two-thirds the length of the carpus), at most only slightly scabrous; 

 anterior internal lobe of carpus subacute, flattened-conical, armed 

 with two or three small corneous scales, of which the apical one is the 

 larger ; dorsal ridge of merus of cheliped furnished only with a longi- 

 tudinal row of small, low, not very conspicuous, scabrous swellings; 

 anterior margin merely slightly scabrous. Inner margin of ischium 

 armed with two stout, low, conical, corneous scale-tipped tubercles, 

 one anterior, one posterior; there may be one or two irregularities, 

 obsolescent tubercles, or nodules on the inner margin between these 

 spines.
