281 



Description. — USNM 118248, from eight miles northeast of Saiaza, 

 Curumani, Magdalena, Colombia. Vomerine teeth in two small, 

 rounded patches, lying close together between the small, rounded 

 choanae; tongue three-fourths as wide as mouth opening, broadly 

 rounded, its posterior border slightly free and very shallowly notched. 

 Snout short, somewhat rounded when viewed from above, slightly 

 pointed in profile, the upper jaw extending appreciably beyond 

 lower; nostrils more lateral than superior, very slightly projecting, 

 their distance from end of snout about one-half that from eye, sepa- 

 rated from each other by an interval equal to about their distance 

 from eye. Can thus rostralis rather well-defined; loreal region flat and 

 nearly vertical, the upper lip barely flaring out below it. Eye rela- 

 tively large and prominent, the black choroid coat showing through 

 the translucent upper lid, its diameter greater than its distance from 

 nostril; palpebral membrane not reticulate; interorbital distance equal 

 to distance between nostrils and both greater than width of upper 

 eyelid. Tympanum very distinct, about one-fourth the diameter of 



Figure 28.— Hyla microcephala, USNM 118248 (X 3).
