FROGS OF SOUTHEASTERN BRAZIL COCHRAN 109 



caDnot be taken very accurately in such small specimens, but if heads 

 of frogs belonging to both species are placed side by side, the difference 

 between the inner extension of the eyeball is quite apparent. 



The original description of sanborni states that vomerine teeth arc 

 absent. In three paratypes of sanborni, USNM 101457-9, the pro- 

 tuberances on which vomerine teeth usually occur can be seen and 

 felt in the mouth. In elongata, the vomerine teeth may be small and 

 moderately developed, or larger and quite heavily developed. 



Both sanhoini and elongata have rather transparent upper eyelids, 

 which allow the dark eyeball to be seen through the skin (in preserved 

 examples, at least). H. nana, on the contrary, has opaque eyeUds 

 which entirely conceal the dark eyeball.

Description. — Adult male, USNM 97308, Manguinhos, near city 

 of Rio de Janeiro. Vomerine teeth in two long, posteriorly-converging 

 series arising in front of the anterior borders of the choanae and ter- 

 minating near the midline and slightly anterior to an imaginary line 

 connecting the posterior borders of the choanae; these vomerine 

 teeth appear rather poorly defined, as they are nearly covered by the 

 skin of the interior of the mouth; tongue less than half as wide as 

 mouth-opening, nearly circular except for a deep notch on its free 

 posterior border; snout rather short and rounded when viewed from 

 above, truncate in profile, the upper jaw scarcely projecting beyond 

 the lower; nostrils superolateral, scarcely projecting, their distance 

 from end of snout about half that to anterior border of eye, separated 

 from each other by an interval very slightly less than their distance 

 from eye. Can thus rostralis not defined; loreal region flat. Eye 

 relatively large, very prominent, its diameter greater than its distance 

 from end of snout; interorbital diameter about IK times the width of
