NO. 1 glassell: three new anomuran crabs 3 



Color in alcohol: Buff with red markings. 



Range: Throughout the Gulf of California, at depths ranging 

 from 40 to 80 fathoms. 



Remarks: This proposed species is allied to P. guatemoci Glassell, 

 1937, but differs from that species by the major hand being smooth,' the 

 inner margin only being armed, the outer a granulated ridge, and with 

 no proximal ridge, instead of being entirely margined with teeth, the 

 surface minutely granulate.

 of carapace and extending past and above the revolute, widely triangu- 

 lar, distal margin; lateral spines blunt, not advanced past the median.
