BURROWING INVERTEBRATES . 
CRUSTACEA. 
The Land Crabs and their habits -The Violet Land Crab — Its burrows, 
its combativeness, and its pedestrian powers — The Fighting Crab, why so 
called — The Racer Crab of Ceylon — Its burrows and mode of carrying off 
the soil — The Robber Crab — Its form and general habits — Food of the 
Robber Crab — A soft bed, and well-stocked larder — The Chelura, and 
its ravages among timber — The Gribble and its kin.

impossible to give more than a selection of some of the more 
remarkable examples. Although, therefore, there are’ many other 
burrowing and semi-burrowing vertebrates, we must leave the 
furred, feathered, and scaled tribes, and pass to those which 
occupy a lower place in the animal kingdom. 
Among the Crustacea, there are very many species which form 
burrows, and which conceal themselves under the sand or mud. 
As, however, these creatures cannot be said to form their habita- 
tions, and the burrows are mostly obliterated by the return of the 
water, they can scarcely be reckoned among those which make 
* homes without hands.’ Some, however, there are which are as 
fully entitled to be ranked among the true burro wers, as any 
creature which we have mentioned, digging a regular burrow in 
the earth, residing in their subterranean home, issuing forth to 
procure food, and retiring to it when alarmed. These are the crea- 
tures so widely famous as Land Crabs ( Gecarcimis ), respecting 
which so many wonderful tales are told, some true, some false, 
and many exaggerated. The Land Crabs are found in various 
parts of the world, and are notable for very similar habits. They
