Coloration of living specimens. — Adult; U.S.N.M. No. 26820; L. S. 

 No. 9043; Mameyes, Porto Rico, March 3, 1900. General color above 

 olive, the dusky markings dark grayish brown, nearly blackish brown 

 below the dorso-lateral fold and on femur; the dorso-lateral fold and 

 narrow edges around the dark markings pale olive gray; the trans- 

 ocular band and cutting edge of lip dark grayish brown; the supra- 

 labial light band pale straw yellow; underside whitish; throat finely 

 sprinkled with dark chocolate brown; iris olive silvery, overlaid with 

 blackish. 



Another adult specimen, same locality and time (U.S.N.M. No. 

 26821, L. S. No. 9011), had the general color a little more clayey and 

 the dark markings darker and arranged longitudinally. (In alcohol 

 the middle line of the back becomes quite light, forming a pale median 

 band from between eyes to vent, bordered on both sides by a blackish 

 line.)

 the elbow; a black mark in the groin; hind limbs pale olive, barred 

 with black; posterior surface of femur with a conspicuous longitudinal 

 streak of silvery white, margined with black; iris golden, overlaid

 back varies between reddish brown through various shades of brown
