LIOHYLA. 225 
7. Liohyla ranoides. 
Lithodytes ranoides, Cope, Proc, Am. Phil. Soc. xxiii. p. 275 (1886). 
Liohyla ranoides, Cope, Proc. Am. Phil. Soc. xxxi. p. 335 (1893). 
Hab. Nicaraaua (Cope); Costa Rica, Buenos Aires, Terraba (Cope). 
Habit not slender. Head relatively rather long. Snout acuminate, somewhat 
projecting, with the canthus rostralis distinct, and with the sides subvertical. Eye 
equal to its distance from the nostril. Tympanum oval, its vertical much longer 
than its horizontal diameter, scarcely one-third the size of the eye. Skin nearly 
smooth, but a pair of feeble folds form an obscure pattern on the scapular regions. 
The length of the body seems to be nearly equal to the distance between vent and 
heel. Disks of fingers and toes truncate. Toes nearly one-third webbed, Two 
small metatarsal tubercles, of which the outer is obsolete. Coloration variable, greyish 
to dark brown, with or without a white median dorsal line or band, and sometimes 
with a light interorbital cross-band. Upper parts more or less distinctly marbled 
with darker colour; lower parts whitish. Limbs dark cross-banded ; the cross-bands 
of the tibia extend on the skin that covers the flexors of the foot so as to be seen 
from below. (After Cope.) 
' This species was originally described from four Nicaraguan specimens, of which the 
largest measured 26 millim. Although Cope, at a later period, recognized the same 
species in some Costa Rican frogs, I am unable to find it among the numerous examples 
sent by Pittier and Underwood. Its chief characters seem to be the acuminate snout, 
short hind limbs, webbed toes, and the peculiar small, oval tympanum, which Cope 
ascribes to all his specimens, and which therefore cannot be regarded as an individual 
or accidental modification. In this respect L. ranoides resembles L. engytympanum ; 
but the latter has a shorter obtuse snout and longer hind limbs. 
8. Liohyla berkenbuschi. 
Hylodes berkenbuschii, Peters, MB. Ak. Wiss. Berlin, 1869, p. 879. 
Hab. Muxico (Peters). 
Snout acuminate, with distinct canthus rostralis. ‘Tympanum large (sex unknown), 
its diameter two-thirds of that of the eye; choane narrower than the eustachian tubes, 
Vomerine teeth on two small approximate transverse prominences behind the choane. 
Sides of the body with some oblong glandular pads and with a strong fold from the 
shoulder to the thigh. Abdominal disk smooth, a cross-fold on the chest. First finger 
a little shorter than the second. The basal phalanges of the toes are united by a 
web extending as narrow fringes to the disks. Disks of fingers and toes well developed ; 
one metatarsal tubercle; a tarsal fold. Upper parts brownish, with darker spots, of 
which one, triangular in shape, between the eyes, is preceded by the lighter-coloured 
snout; upper lip and limbs cross-banded ; sides with black spots, marbled with yellow;
