PANAMA CANAL ZONE: Seven mi. northwest of Miraflores Locks, TNHC 

 23109 (type of Hyla foliamorta) . 



13. PALPEBROGRANULATA group 



Members of this group are moderate-sized Hyla with the vomerine 

 teeth in two, short, transverse series on a level with the posterior 

 margin of the choanae; with well-developed patagia but without ulnar 

 or tarsal ridges or dermal heel appendages; with distinct dorsal pat- 

 terns; and with distinct crossbands on the thighs. A distinct, white, 

 subocular blotch runs from the eye to the lip on each side. The group 

 is presently represented by only one species.

Diagnosis. — A moderate-sized Hyla with the vomerine teeth in two 

 short, transverse series (on a level with the posterior margin of the 

 choanae), reduced webbing between the toes, a well-developed pata- 

 gium, distinct crossbands on thighs and shanks, and dark flecks on 

 chin, throat, and venter. There is a distinct, white, subocular blotch 

 on each side that extends from eye to the margin of the Up. 



The form and position of the vomerine teeth somewhat resemble 

 those in Cryptobatrachus and Hyla phantasmagoria, but palpebrogranu- 

 lata does not seem to be closely related to either and can be immedi- 

 ately distinguished by its patagium. The patterned thighs and the 

 granulations on the back separate it at once from the members of the 

 leucophyllata group. 



Description. — USNM 152757, from Medina, Cundinamarca, Colombia. 

 Vomerine teeth in two short, transverse series, lying close together 

 on a level with the posterior borders of the small, rounded choanae; 

 tongue two-thirds as wide as mouth opening, broadly rounded, its 

 posterior border fused and unnotched. Snout moderate, U-shaped 

 when viewed from above, slightly rounded in profile, the upper jaw 

 extending a little beyond lower; nostrils lateral, hardly at all superior, 

 somewhat projecting, their distance from end of snout about one- 

 third that from eye, separated from each other by an interval equal to 

 about two-thirds their distance from eye. Canthus rostralis moderately 

 defined; loreal region slightly concave and a little oblique, the upper 

 lip flaring out slightly below it. Eye neither large nor prominent, its 

 diameter not quite equal to its distance from nostril; palpebral mem-
