 in the form of the propodite of the third left leg, the outer border of the 

 upper surface of which is not carinated and indeed is sometimes not defined 

 m any way. 



It agrees with P. varif>es, and differs from P. deformis, in having longitu- 

 dinal rows of granules, but no crest, on the upper surface of the dactylus of 

 the left cheliped ; in having the outer surface of the dactylus of the third left 

 leg longitudinally carinated near the lower border ; and in the absence of

 in havincr (i) the whole upper and outer surface of the left hand closely and 

 uniformly granulous, and the granules along the upper (inner) border hardly 

 enlarged except near the carpal end, and (2) the outer surface of the propo- 

 dite of the third left leg granulous and pitted. 



It agrees with P. deformis, and differs from P. varipes and asper, in having 

 the outer surface of the dactylus of the third left leg longitudinally canali- 

 culate (not carinate). 



It agrees with P. varipes and asper, and differs from P. deformis, in 

 havinf^ the dactylus of the left hand granulous and non-carinate. 



It a<^rees with P. asper, and differs from P. deformis and varipes, in the 

 absence of a carina from the (hardly defined) outer border of the upper
