All six tadpoles are colored alike, except that in the larger specimens scattered white flecks are present on the ventral surface of the body, and the dark reticulations continue farther posteriorly on the caudal fins than in the smaller tadpoles. In two specimens the third lower tooth-row is only about one-half the length of the other lower rows, and in one specimen the second lower tooth-row is shorter than the first. Coloration of tadpoles in life: "Body olive-brown with silvery green flecks laterally. Caudal musculature olive-brown with greenish tan flecks. Fins brown with greenish gold flecks. Iris deep bronze." (Duellman, field notes, February 19, 1965). One recently metamorphosed young (KU 91808) has a snout-vent length of 12.4 mm. In life this frog had a pale tan dorsum with dark brown markings, yellowish tan posterior surfaces of thighs, grayish brown throat, and bronze iris. _Remarks._--The identity of Cope's _Hyla puma_ has not been known. The name has appeared in various compilations, but no workers have referred any of their specimens to that species. Examination of the holotype (USNM 13735), an adult female, revealed the presence of the following combination of characters: snout-vent length 45.8 mm., snout blunt above and rounded laterally, nostrils close to tip of snout, lips thin and flaring, a vestige of a web on the hands, feet about one-half webbed, tarsal fold weak and extending about two-thirds length of tarsus, dorsal markings consisting of a faded dark interorbital bar and a pair of faded longitudinal brown marks connected by a transverse band in the scapular region. The type agrees well with specimens of _Smilisca wellmanorum_ (Taylor, 1952); the vestigial webbing on the hands and the dorsal coloration are especially significant. Consequently, we consider _Hyla wellmanorum_ Taylor, 1952, to be a synonym of _Hyla puma_ Cope, 1885. Cope gave only "Nicaragua" as the locality for _Hyla puma_. The specimen was part of a collection received at the United States National Museum from Lt. J. F. Moser. Among the species in the collection are _Dentrobates pumilio_, _Phyllomedusa helenae_, _Corythophanes cristatus_, _Pliocercus dimidatus_, _Tretanorhinus nigroluteus_, and others characteristically found on the Caribbean lowlands of Central America. Thus, it seems reasonable to assume that the type specimen of _Hyla puma_ came from the Caribbean lowlands. Though no other Nicaraguan specimens have been found by us, numerous specimens are known from the Caribbean lowlands of Costa Rica.
