Diagnosis. — Superior incisors with a main groove dividing the tooth into 

 two unequal portions; the outerobviously the smaller; the inner, larger moiety 

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

 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 all (he 

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

 67. 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 obsolete 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 denial discrepancy lies elsewhere. In bursarius,
