insertion of the (ore arm. Tiie extreme edjjeof tlie upper jiiw i.s diirU, 

 and tlie space lu'tween 'iii.s an<l the preoenlar line r.ither li;,'hter than 

 the ground eoh)r. In the extension of tlii.s liglit Hpaee baekwardH 

 it beeome.s lij-liter, until from beneath the eye it passe.s beh)\v the 

 postocnlar band to the base of the forearm as a grayish-wliite vitta, 

 usually about half as broad as the one above it. Sometimes a series 

 of seattered rounded spots may be traced alonjj the side in eontinuance 

 of the dark postoeular vitta. The extremities above are transversely 

 and narrowly but indistinctly barred with darker. Tlie rest of the 

 legs is uniformly lle.sh color (thiifhs posteriorly dusky) except a few 

 a{j{;ref;ated pustules below and about the anus, which are wiiilo (no 

 marking on the inner faces of limbs); this is seen in other species, but 

 is very distinct here. The immediate border of the anus is brown; 

 beneath, white; edfje of {j[ular .sac, black. 



In some specimens, especially tho.se from Fort Tejon, the prevalent 

 color above is ash{j''«>.v, with an elonjjated blotch alon<,' each side of 

 the back for its whole lenj^th, and one or two others on each side of 

 tho.«e dorsal blotches are nearly wantiufjf. Sometimes the exterior edj^cs 

 of tae tibia and feet (when Hexed), are blotched with l>rown. 



This variety resembles JI. s<juircU<(, but the head is less depressed ; 

 the colors are darker; the (lorsal blotches are larjjer, and elonj,'ated 

 lon^jitudinally in two or three series; the white maifjjin to the niiu^h 

 darker jxistocular vitta is broader; the body is stouter, and usually 

 more or less {granulated. The toes are less deei»ly webbed. 



Thell{,'ure of this species in volume ten of the Pacifn; l\ailr(>ad Sur- 

 veys repre.scids an interdij;ital membrane anteriorly, which does not ex- 

 ist, and that of the posterior limb is too extensive.
