Hyla andersonii Baird. 

 Anderson Tree Toad. 



Color, when fresh, beautiful pea-green on back and upper surfaces 

 of limbs. This color is bounded all along its edges on head, flanks, 

 sacral region posteriorly, tibial region and hallux, by a narrow line 

 of pale whitish, with just a very slight tint of dilute azure in some 

 places. On femoral region this pale boundary-line is not evident. 

 From nares, to and including eye, back towards axilla, a deep indigo- 

 black streak or band, this not wider than vertical diameter of eye, 

 and sharply and conspicuously evident, especially being due to pale 

 narrow boundary-lines. These blackish bands do not extend across 

 tip of nose. Edge of upper jaw paler green all around. At axilla 

 indigo-black band becomes a beautiful lavender-gray, which extends 

 well back in bright color toward groin, but not to latter. Just little 

 above axilla it sends forward a narrow dark grayish-lavender branch, 

 which widens out into broad dusky-lavender or neutral tint of throat 

 or vocal vesicle. Edges of lower lip slightly, though rather broadly, 

 pale violet or purplish all around to greenish patch, which begins 

 about opposite front part of eye. Greenish of upper surface of fore 

 limbs is thus completely separated from that of back, and is bordered 

 with a fine or narrow pale line all around, which at shoulder assumes 

 a slightly bluish hue. Breast livid pale lavender, papilla? larger or 

 more whitish, though all annectant colors fuse gradually into it. 

 Hand above dull prussian-blue, and this color not sharply demarked 

 from bright orange-red .of hand below, which latter color is also 

 brightest in the first two fingers. In fact, bluish of upper surface of 

 hand is largely superiorly external, only extending over outer half, 

 and in the basal joint of the third finger and nearly whole of upper 

 surfaces of the fourth finger. The two inner fingers are brilliant 

 orange-red. Bluish of hand above extends along forearm to elbow, be- 

 hind narrow yellowish-green line separating green above. On lower 

 surface of forearm it fades beautiful violet, and next to yellowish-green
