through which it has to pass. The Oceanic Swimming Crab is among crustaceans what 

 the albatross is among birds, being able to sustain itself for days together without needing 

 rest, and whenever it does seek a brief repose, needing nothing but the floating algae 

 as a temporary resting-place. The movements of this species are achieved with an 

 easy grace and freedom that remind the observer of the swallow's flight, as the crab 

 flies swiftly through the water, its claws ready to seize their prey, and its limbs held

This species has a very wide range, and is found throughout the warmer seas. It

 The species is notable for the shape of the carapace, and the sharp spine into which 

 each side is developed. 



THE strange-looking creature which is represented in the illustration, is nearly as

 crustacean, the FORCEPS-CRAB roams the ocean as freely as the bird roams the air, shoot- 

 ing through the waves with arrowy swiftness in chase of prey, gliding easily along just 

 below the surface, hanging suspended in the water while reposing, or occasionally lying 

 across some floating seaweed. The chief peculiarity of the Forceps-crab is the struct- 

 ure from which its name is derived, the wonderful length of the first pair of limbs, and the 

 attenuated forceps with which they are armed. Though not possessing the formidable
