X)f the tongue. A conspicuous fold of skin across the breast. Fingers 

 -with, at most, a rudiment of a web. Toes with a slight web at their 

 basal joints. Disks of all the digits small. Limbs of quite variable 

 length, the heel reaching only to the tympanic disk, or to the nostril. 

 Skin almost everywhere granulated, finely on the back, more coarsely on 

 the lower surface. 



General color, varying from light ash to fawn and purplish-brown ; 

 below, cream color. On the back and sides there may, in nearly all 

 specimens, be seen five dark stripes or rows of spots. One beginning 

 on the head, runs along the back, often forking on the urostyle. On 

 the head, this stripe may expand so as to involve the eyelids, or there 

 may be spots on the lids distinct from the median stripe. On each side 

 of this dorsal stripe is another, which begins behind the eye and ceases 

 just in front of the thigh. Another stripe begins on the snout, runs 

 through the eye, over the tympanic disk and the shoulder, and fades out 

 -along the side. A whitish line runs along the upper lip to the shoulder. 

 Sometimes the median and the lateral bands next it may be broken up 

 into distinct spots, or these bands may be obsolete. The limbs are more 

 • or less barred or spotted with dusky. 



Under the name nigritus I have included forms which are assigned by 

 Prof. Coj)e to three distinct species, nigritus, feriarum, triseriatus. I do 

 /SO because, at the present time, I do not think that the distinctions are 

 sufficiently constant to characterize species. That the student may 

 recognize the forms and accord them specific value, if he so desires, I 

 state the differences. 



Snout acuminate; width of head in length of head and body 2.8 to 3 

 times; heel reaching in front of orbit; size larger; color leaden or fawn, 

 with three rows of dark spots above; these sometimes united into con- 

 tinuous bands. South Carolina to Mississippi. nigritus. 



Snout shorter ; width of head in the length 3 to 3.25 times ; heel reach- 

 ing to front of orbit ; length of body in total length of hind leg, from 

 1.40 to 1-70; color ash or brownish, eyelids involved in median stripe, 

 three parallel stripes above, seldom interrupted. Eastern United States 

 to Illinois. feriarum. 



Snout drawn out; width of head in length 3.5 to 3.6 times; heel 

 preaching only to tympanic disk ; length of body in total length of hind 

 leg, 1.24 to 1.50 times; color ash to brown, with three parallel dark 

 stripes, the median often forking behind ; a distinct spot on each eyelid. 

 New Jersey to New Mexico and Idaho. triseriatus. 



G. ni^gritus is chiefly or wholly southern, feriarum eastern, and triseria- 

 tus, the short-legged and peaked-nosed form, mainly western, in distribu- 

 tion. All that I know of from Indiana belong to the variety feriarum.
