the comparative length of the hind limb. The two specimens on which Peters based 
this species were both males.

Hyla gabbii, Cope, Journ. Ac. N. Se. Philad. viii. p. 103 (1877); Bouleng. P. Z. S. 1898, p. 478 *. 
Hyla salvini, Bouleng. Batr. Sal. p. 872; Werner, Verh. zool.-bot. Ges. Wien, 1896, p. 344. 
Hab. Costa Rica, Sipurio (Cope), La Palma, Monte Rotundo, alt. 1600 metres, and 
Laguna de la Palma (Underwood), Cartago and San José (Mus. Brit.; Mus. Nac. 
de Costa Rica, San José). 
Vomerine teeth in a transverse series, interrupted in the middle, between the choane, 
which are moderately open. Snout broad, short, obtuse, rather depressed, with rather 
obtuse canthus and with sloping concave sides. Distance of the nostril from the eye 
equal to the diameter of the latter. Interorbital space wider than the supraocular 
cover. Tympanum distinct, one-half the area of the eye. When the hind limb is 
carried forwards, the heel reaches the end of the snout. ‘The three outer fingers are 
three-fourths webbed, and also the two inner fingers are connected by a narrow web ; 
their disks as large as those of the toes and as the tympanum. No external rudiment 
of pollex. Toes almost entirely webbed; a tarsal fold. Upper parts smooth or 
nearly so; abdomen and throat rather coarsely granular; a short fold above the 
tympanum, and sometimes a transverse one across the chest. No fold or appendage 
above the vent or on the heel; forearm with a narrow tubercular fringe. Upper 
parts greyish, sides and anterior and posterior faces of the hind limbs reticulated ; no 
spots on the lips.

20. Hyla pseudopuma, sp.n. (Tab. LXXII. figg. A, B.) 
Hyla puma, Bouleng. P. Z. 8. 1898, p. 478 (not Cope). 
Hab. Costa Rica, La Palma, alt. 1600 metres (Mus. Nac. de Costa Rica, San José). 
Vomerine teeth in two transverse patches, slightly separated from each other, 
between the posterior part of the choane. Snout short, rounded, depressed, with 
obtuse and concave canthus and with sloping concave sides. The diameter of the eye 
* The specimen in the Natural History Museum, identified with Cope’s Hyla gabbii, has the fingers as 
broadly webbed as in typical H. salvini ; but it has the upper lip margined with whitish, as mentioned by Cope 
in his description of H. gabbii. I do not consider this to be sufficient for the distinction of two species.
