THE TORTOISE FAMILY 

 Testudinidae 



The group of tortoises contains many species that are 

 either beautiful, or curious, or remarkable for their size and 

 age. Quite a number of species are handsomely colored, but 

 the majority are perfectly plain. 



Two distinct types have been developed. The ordinary, 

 thick-shelled, uncolored tortoises, some of them of great size, 

 constitute the majority of the species. The smaller section 

 is made up of small tortoises, some of which have a prac- 

 tical hinge in the centre of the lower shell. These are strictly 

 land-going animals, and some of them even burrow in the 

 earth, in sandy situations where digging is easy. 



The Giant Tortoise 1 is a good species to lead this entire 

 Order. If there be aught in the theory of "the survival of 

 the fittest," then thi> creature is clearly entitled to the lead-
