470 CHELONIA. 



Loc. — Puget Sound (Oregon), and Sacramento Eiver (California). 



Plate XXXII, fig. 1, represent the outline, half from above and 

 half from below, of a female specimen, from Sacramento River, Cali- 

 fornia. 



Fig. 2, a similar outline of a male individual, from Puget Sound, 

 Oregon. 



Figs. 3-15, exhibit a series of views taken from young specimens, 

 collected about Puget Sound also, in order to show their relative pro- 

 portions of length, width, and depth, as w^ell as the granules and ridges 

 of the carapax; and the sternum also, in order to give a correct idea 

 of the general appearance of the species throughout the various stages 

 of its growth. • 



All these figures are drawn the size of life. 



Fam. TESTUDINIDAE. 



This family includes the " Land Tortoises," properly so called. The 

 scanty materials of this group now at our command, will not permit 

 us entering into anything like details, whether historical or structural. 



Genus TESTUDO, Linn. 



Gen. Rem. — This genus has been subdivided by modern writers,

 not, as yet, been properly defined, hence the impracticability of refer- 

 ring the following species to its proper natural group.
