James Island has been suggested by Baur as the probable habitat of 

 this species on the strength of the dome-shaped carapace. The meas- 

 urements of the carapace, however, are duplicated by specimens from 

 Iguana Cove, but we have seen no skulls from this locality with a deep 

 recess before the occipital condyle and sharp edges to the pterygoids 

 as in Giinther's figure of this species.

Range. — ( ?) Chatham Island. 



This species was described from a specimen of uncertain origin 

 obtained by Wallace from the Bullock collection where it was cata- 

 logued as " Indian Tortoise." Chatham Island has been suggested as 

 the habitat of the species by its describer on the clue given by Captain 

 Porter's remark that the James Island tortoises were round. Most 

 closely allied to T. galapagoensis.

Range. — Albemarle Island from Iguana Cove eastward along the 

 southern slopes of the two southern volcanoes to Cape Woodford and 

 Perry Isthmus, absent from the barren southern slopes of the vol- 

 canoes. Vertical range from sea level to 4,000 feet altitude. (^Pe- 

 trel., Albatross., 1888, Rothschild Expedition, Hopkins Standford 

 Expedition.) 



This species was found rather common near Iguana Cove in June, 

 1899, but during our previous visit in December, 1S98, only two were 

 found, the tortoises being at that season of the year in the high 

 plateaus. This species inhabits a moist region supporting a heavy 

 growth of underbrush and small trees. Food is abundant throughout 

 the year and the conditions are ideal for the great development of tor- 

 toises in size and numbers. The largest living tortoises are perhaps 

 to be found here. We observed a few large males that we estimated 

 would weigh about four or five hundred pounds. 



The shells in this species are more symmetrical, the carapace being 

 rounded in horizontal outline and more or less dome-shaped without 

 much anterior flaring. The limbs are considerably shorter than in T. 

 microphyes.
