304 A NATURALIST IN BORNEO 



I cannot say whether the Gonodactylus uses its chelipeds 

 in defence only, but it is conceivable that a stunned 

 animal could be held between the basal and " dumb-bell" 

 joints and quietly devoured ; while the Squilla, not 

 stunning its prey first, has need of a more efficient 

 grasping apparatus.
