around anus very coarsely granular. Apparently no skinfold across 

 the chest. (In the male, no external vocal sac; a dark roughened cal- 

 losity on top of first finger.) 



Dimensions. — Head and body 79 nun.; head length 23 mm., width 

 26 mm.; femur 30 mm.; tibia 32 mm.; foot 26 mm.; hand 21 mm. 



Color in alcohol. — Upper surface of body China blue, with small 

 white spots scattered irregularly upon it; sides of body with a very 

 sharp but irregular line of demarcation between this dorsal coloring 

 and a white lateral band that runs between axilla and groin, of which 

 the lower anterior half is set off by a black line beginning at the angle 

 of the jaw, continuing in front of the shoulder and below the axilla; 

 in the groin and along the sides a few large irregular blue spots in this 

 white field. Upper surfaces of arms blue, except for fingers and a 

 white band around upper arm continuous with the white lateral area. 

 Upper leg surfaces blue, except that inner parts of tarsus and foot 

 are white, with a few irregular blackish bars extending across anterior 

 and posterior parts of femur, and on inner tarsus. A narrow glandular 

 white line edged with back along the lower lip, continuing behind 

 angle of mouth and widening to form the white lateral band pre- 

 viously mentioned; a white line along outer part of forearm and hand 

 following the glandular ridge, another along outer side of foot from 

 tip of fifth toe to heel, on which region it is very prominent, and another 

 on the transverse glandular ridge in front of the anus, all these white 

 lines more or less edged with black. Anal region blackish. Ventral 

 surface immaculate pale olive-buff. Throat (in AMNH 17414) and 

 chest coarsely reticulated with dark brown. 



Color in life. — From a painting by Sandig. Upper parts bottle 

 green to grass green; a white line along border of lower lip continued 

 across and in front of forearm as a widening white stripe edged below 

 by black, and changing midway on the sides and in groin to ochre 

 yellow. Forearm white tinged with violet below with a few delicate 

 brown or black reticulations. Fingers brown, the disks white. Lower 

 parts of legs ochre yellow, paling to cream-buff on the feet. Throat 

 and breast seal brown with several large chrome-yellow spots, belly 

 pale cinnamon, anal region darker. Iris pale smoke gray to pale pea 

 green, with the pupil a vertical black slit. 



Variations. — Three adult males, USNM 96922-4, from Montserrat, 

 Campo Bello, all show a brown roughened pad on the upper side of 

 the base of the first finger on the semicircular projection. They agree 

 in having the sides of the head and body, as well as part of the upper 

 limb surfaces, much paler than in the described specimen. The 

 narrow black area in front of shoulder and axilla hmiting the lower 

 border of the white lateral stripe is also much reduced or lacking in 

 these examples. While they all have rather decidedly pointed snouts,
