inner and a very small outer metatarsal tubercle (one of the 

 latter lacking). Skin smooth except for a few small tubercles 

 on the side of the head. Color above deep mouse grey, a little

 canthus rostralis, two black bands from the eye in front and 

 behind ear and inclosing a broad dull yellow band, a broken 

 interocular black band and a few black marks on each side of 

 the nape and behind the shoulder; upper li]) mostly black; 

 belly pale yellow faintly marbled with brown ; inguinal region 

 and anterior region of femur black with well defined pale 

 spots; posterior region of femur and inferior surface of tibia 

 l)lack with pale spots. 



Total length, 53 mm.; length of head (to posterior margin 

 of ear), ]8 mm.; width of head, 20 mm.; length of snout, 9 

 mm. ; fore leg to tip of longest finger, 32 mm. ; hind leg to tip 

 of longest toe, ^J mm. ; hind leg to heel, 49 mm. 



Notes 0)1 Parafypes : Fifteen specimens have been used in 

 ])reparing the diagnosis of the species, and the structural char- 

 acters and coloration are remarkably constant in this series. 

 The type difil'ers from most of the others in that one of the 

 lateral black head bands is obsolete. In the normal coloration 

 there are three black bands from the eye to the mouth, preceded 

 by a black spot on the lip. One specimen (No. 48407, Univ. of 

 Mich.) differs from all of the others in coloration. In this 

 specimen the back is largely covered with irregular black spots 

 surrounded with narrow olive gray lines and more or less 

 relieved by small punctulations of the same color; the thighs 

 are liroadly cross banded with black ; the lateral head bands 

 are so wide that the interspaces are restricted to narrow pale 

 gray lines ; the ventral surface is dark brown with dull white 

 variegations and the under-surface of the thighs is ])lackor 

 bone brown with numerous well defined wliitc spots.
