 Hyla lichenosa. part., G'unth. Cat. p. 102, pi. viii. f. C. 



Very closely allied to H. vemilosa, from -^hich it differs principally 

 by a smaller tympanum. The diameter of the latter equals one 

 third or one half the diameter of the eye, and equals in size the 

 digital disks. Upper surfaces covered with large flat warts ; derm 

 of parotoid region thickened, limited by a strong fold above the 

 tympanum. Brown above, generallj' with small black round spots ; 

 generally a broad white band from the upper eyelid to the loin ; 

 limbs not, or indistinctly, cross-barred ; lower surfaces whitish, 

 immaculate. From snout to vent 62 millim.

Tongue circular, entire, and slightly free behind. Vomerine teeth 

 in a straight interrupted series on a level with the hinder edge of 

 the ehoanae. Head broader than long ; snout short, rounded, 

 scarcely longer than the diameter of the orbit ; cauthus rostralis 

 rounded ; loreal region concave ; interorbital space as broad as the 

 upper eyelid ; tj'mpanum two thirds the diameter of the eye. 

 Fingers one-third webbed ; toes nearly entirely webbed ; disks of 

 fingers nearly as large as the tympanum, of toes a little smaller ; 

 subarticular tubercles very prominent ; a slight tarsal fold. The 

 hind limb being carried forwards along the body, the tibio-tarsal 

 articulation reaches between the eye and the tip of the snout. 

 Upper surfaces with small smooth warts ; a strong fold from the 

 upper eyelid to the shoulder ; throat, belly, and lower surface of 

 thighs largely granulate. The back covered by a large dark 

 reddish-brown spot, distinctly limited from the light reddish brown 

 of the remaining parts, but blending posteriorly into the light 

 coloration of the hind limbs ; the anterior limit of this spot is a 

 straight line drawn across the front of the interorbital space and 

 the upper eyelids ; the lateral borders of this spot, to the sacral 

 -region, very light, almost white ; limbs immaculate ; lower surfaces 

 whitish, immaculate. From snout to vent 46 millim.
