Diagnosis. — Superior incisors with n main groove dividing tlic tootli in(<i 

 two unequal portions; the outer obviously the smaller; the inner, largerinoiety 

 marked by an extremely fine marginal groove, faint, obscure, or perliaps 

 sometimes obsolete. Tail and hind feet in adult life naked, or nearly so. 

 Otherwise like G. bursarius. 



Habitat. — Georgia, Florida, and Alabama. 



Authors speak of the upper incisors as single-grooved. But in nil (ho 

 numerous specimens examined, the upper incisors arc double-grooved, as in 

 G. bursarius, the fine second groove being perceptible as a delicate line of 

 impression along the inner margin of the tooth. It is perfectly distinct, as a 

 rule ; and in no case have I failed to recognize clearly at least a trace of it, 

 though in some instances it is faint, and liable to be overlooked if not closely 

 examined. Baird says that this groove becomes ol)solete in old age, implying 

 that such is the rule ; but, while not doubting that this may occur, I must 

 consider it exceptional. G. tuza, therefore, has double-grooved incisors, like 

 G. bursarius. The point of dental discrepancy liiis elsewhere. In bursarius,
