Batrachians from E, Bolivia. 191 
Trinidad and Caracas) have the rostral almost as deep as 
broad, its upper portion two-thirds its distance from the 
frontal, and a specimen of U. guerini (from Pernambuco) has 
the rostral only two-thirds deep as broad, its upper portion 
two-thirds its distance from the frontal. In every case, 
however, the two species may be told apart by the loreal, 
which is moderate and not much longer than broad in guerint, 
whilst in newwiedi@ it is very small and much longer than 
broad.
