CRUSTACEA — WIIITKLEfiOK. 139' 



The above enuiuoration includes ei;^lit (lislinct groups oi- chisses, 

 over fifty genera and sixty-li\(' s[t(ici(^s, with a total of three 

 hundred and seventy-two free indivichials, and it may l)e estimated 

 that fully a tliird of the once denizens of this s([uare foot of the 

 rioor of the Pacific was lost after its entanglement in the fisher- 

 man's line. What the original population of this stone may have 

 been is impossible to say ; it would probably be less difficult to 

 estimate the quantity of sand grains in the stone than to ascertain 

 the number of individual organisms still remaining on its surface.

 ing thirty-eight genera and forty-nine species. The following
