138 U. S. NATIONAL MUSEUM BULLETIN 2 06 



blunt but less distinct outer metatarsal tubercle; a very fine glandular 

 line along inner side of tarsus, not enlarged to a ridge or fold; no 

 dermal appendage on heel. Body stout, in postaxillary region equal 

 to greatest width of head. When hind leg is adpressed, heel reaches 

 to nostril; when limbs are laid along the sides, knee and elbow touch; 

 when hind legs are bent at right angles to body, heels considerably 

 overlap. Skin of upper parts faintly granular or pustular; a distinct 

 glandular ridge encircling upper part of tympanum; skin of throat 

 very finely granular, of chest and belly more coarsely granular, of 

 lower femur minutely granular; a prominent skinfold across the chest. 

 A pair of external vocal sacs. 



Dimensions.' — Head and body 42.5 mm.; head length 13.5 mm., 

 width 12.5 mm.; femur 19 mm.; tibia 22 mm.; foot 17.5 mm.; hand 

 10.5 mm. 



Color in alcohol. — Ground color of upper parts fawn color, with a 

 darker mottling of anastomosing spots over head and body; arms and 

 legs with definite dark crossbars; groin and anterior and posterior 

 surface of femur with pale olive and dark sepia reticulations; loreal 

 region with irregular dark spots; upper lip with an indistinct darker 

 border; entire lower surfaces immaculate deep olive-buff. 



Color in life. — From a sketch by Sandig of one of the cotypes: 

 Dorsal ground color drab, with indistinct mottlings of sepia all over 

 back, becoming darker on head and suggesting a dark interorbital bar 

 or triangle ; groin and proximal half of femur canary yellow, with heavy, 

 black, more or less vertical reticulations; outer anterior half of femur 

 with more regular dark brown crossbars; forearm and tibia with less 

 prominent brown crossbars; inner surface of tarsus pale gamboge, 

 outer surface drab with numerous brown bars extending onto the two 

 outermost digits; the disks of toes and fingers above dark at the base; 

 ventral surface pearl gray with vinaceous suffusions on throat and 

 under part of limbs; a suffusion of canary yellow on under surface of 

 tibia, on anterior part of femur and below groin, these containing the 

 terminations of the brown reticular markings. Iris wax yellow, 

 pupil black. 



Variations. — The numerous examples of this common form show the 

 same extreme degree of variation in pattern that is met with in its 

 southern relatives, H. hayii and H. nasica, and their bodily propor- 

 tions are quite close to those of nasica. The described specimen has 

 an interorbital width equal to IJ^ times the upper eyelid, while younger 

 specimens have it almost twice the upper eyelid. The fingers in the 

 type and several of the Lassance specimens appear to be completely 

 devoid of a web. In other examples there is a slight rudiment of a web, 

 not so extensive in any specimen oi Juscomria, however, as in nasica 

 from Santa Catarina.
