Bufo granulosus Spix, Spec. Nov. Testűd, et Ranarum, 1824, p. 51, tab. XXI, 
fig. 2; Boulenger, Cat. Batr. Sal., 1882, p. 324. 
Bufo nasutulus Steindachner, Exp. Novara, Amphib., 1869, p. 45. 
One specimen ; length 41 mm. from snout to vent. 
Outline of head a semiellipsis, but the snout above the upper jaw 
nose-like projected and truncate on its end. Nostrils on the upper surface 
of the snout upwards directed. Edge of the upper jaw in some degree 
horizontally dilated and covered with a horny deposit. A low ridge round 
the eye studded with spiny tubercles ; a horny ridge on the anterior part 
of the canthus rostralis extending above the nostril nearly to the tip of 
the snout, not confluent with that on the other side and separated behind 
from the circumorbital ridge by some spiny tubercles ; below the nostril 
a short ridge furnished with a horny crust ; close to the posterior part of 
the circumorbital ridge there are spiny tubercular rows, indicating a short 
orbitotympanic and an obliquely inward directed parietal ridge. Interorbital 
space concave, little broader than the upper eyelid,* studded with a few 
scattered tubercles. The smooth tympanum not very distinct, its horizon¬ 
tal diameter shorter than a half of the width of the eye. First finger not 
or slightly extending beyond second ; toes half webbed ; subarticular tu¬ 
bercles on the fourth toe double ; two moderate metatarsal tubercles ; 
tarsal fold absent, tarsus studded all over with sharp spiny tubercles. The 
hind limbs are unfit for being carried forwards along the body. Upper 
surfaces thickly covered with conical warts. Parotoids moderate, triangu¬ 
lar, as long as the longest diameter of the circumorbital ridge. Light 
brown above with darker confluent spots ; greyish-white beneath, with a 
few darker spots.

Hyla Spegazzinii Boulenger, Ann. Mus. Genova, (2) VII, 1889, p. 247, tab. II,

Six specimens in the length of 48, 57, 58, 60, 60 and 63 mm. 
from snout to vent. 
Tongue subcircular, about as long as broad, adherent, slightly emar- 
ginated behind. Vomerine teeth in two angularly broken (| I), distinctly 
* On a specimen from Surinam, received through the kindness ot Dr. Stein¬ 
dachner, this space distinctly broader.
