Two new Frogs from Brazil. 123 
Leptodactylus pumilio, sp. n. 
Tongue oval, entire. Vomerine teeth in short transverse 
series close together behind the level of the choane, Ileal 
as long as broad ; snout rounded, scarcely projecting beyond 
the lower jaw, a little longer than the eye; canthus rostralis 
obtuse ; loreal region very oblique, concave ; nostril nearer 
the tip of the snout than the eye; interorbital space much 
broader than the upper eyelid; tympanum hidden. Fingers 
with swollen tips, first a little shorter than second, which is 
one-half the length of third; subarticular tubercles strong. 
Toes with the tips dilated into small dises, which are longer 
than broad ; no dermal border ; subarticular tubercles mode- 
rately large, moderately prominent; two small, feebly promi- 
nent metatarsal tubercles, The tibio-tarsal articulation reaches 
the eye; tibia half the length of head and body, as long 
as the foot. Skin smooth, shiny. Dark brown above, with 
ill-defined darker spots on the head and body, and cross- 
bands on the limbs; brownish white beneath, speckled and 
vermiculate with dark brown. 
From snout to vent 20 mm. 
A single female specimen. 
In the dilated tips of the toes this small frog is related to 
L. hyledactylus, Cope, L. discodactylus, Blgr., L. pulcher, 
Bler., and L. mantipus, Blgr., but differs from all of them in 
the hidden tympanum. 
Hyla hilli, sp. n. 
Tongue round, entire and slightly free behind. Vomerine 
teeth in short U-shaped series on round bases, close together 
between the rather small choane. Head small, a little 
broader than long, feebly depressed ; snout rounded, scarcely 
projecting beyond the mouth, as longas the orbit ; no canthus 
1ostralis; loreal region feebly oblique, slightly concave ; 
nostril nearer the tip of the snout than the eye, which is 
rather small ; interorbital space as broad as the upper eyelid ; 
tympavum very distinct, 2 the diameter of the eye. Fingers 
rather short, }-webbed, the discs moderately large, a little 
smaller than the tympanum ; no distinct rudiment of pollex. 
Toes rather short, entirely webbed, the discs nearly as large 
as those of the fingers. ‘The tibio-tarsal aticulation reaches 
the shoulder; heels overlapping when the limbs are folded at 
right angles to the body; tibia a little less than 3 the length 
of head and body. Skin smooth above, with a few very small 
warts on the head ; large flat granules on the throat, on the 
belly, and on the proximal half of the lower surface of the
