 Cheliped lighter than carapace and covered with small granules of light 

 purplish vinaceous color. Outer surface covered with long courge green 

 hair. Ground color of ambulatory legs same as carapace but almost 

 covered with irregular patches of creamy white with pinkish tone. Hair 

 on legs pale yellowish white. (Petersen) 



Habitat. — Shore, Pocillopora colony, and shallow dredging. 

 Depth. — Shore to 13 fms. 



Remarks. — While secured more abundantly in the Pocillopora coral, 

 P. pygmaeus is also gathered in ordinary shore collecting, where it is likely 

 to be overlooked because of its infinitesimal size. Those at Barrington 

 were obtained by use of the diving helmet, those in Cormorant Bay by 

 shallow dredging.
