distance from same to nostril and one and a (juarter the distance between

 lai) by the length of the toes. Two well-marked palmar tubercles.

Cohu' above, olive brown; below, yellowish, olive shaded in the mid- 

 dle. The inferior yellow risi's on the sides as short l)lotches; above 

 them are sevcnil ill-delined yellowish .spots. I'arotoid region yellow, 

 with a <listinct black vertical bar. Limbs brown, cross-banded; tail 

 yellow, with brown sjiots. 



The above description is taken from the type from Heesley's Point, 

 N. .1., in the .Miisi'um Academy Phihulelpiiia. Another specimen 

 ( Miirj) from the same locality, in the National .Museum, dilVers in two 

 important particulars: The palatine teeth iire not brush-like, but are 

 conliiH'd to the crest of tii<' lidge, and the tail is a little longer than the 

 head and body. The niuz/le is ratlu-r longer and tiie mucous pores 

 more numei'ous. It may belong to another species, as the .1. fifirinum, 

 which it much resendtles, l)ut its eleven costal folds are a notable pecu- 

 liaiily. Tlic A. hitolor, though nearest the .1. /(V/r/MKMj, appears dis- 

 tinct, after a <'aieful scrutiny of several individuals.
