minate, with prominent upper lip, longer than the greatest orbital diame¬ 
ter, once and a half as long as the diameter of the eye ; canthus rostralis 
none : loreal region oblique ; nostril a little nearer to the eye than the 
diameter of the latter, distinctly nearer to the tip of the snout than to the 
eye. Interorbital space broader than the upper eyelid; tympanum very 
distinct, not quite two thirds the diameter of the eye. Fingers mode¬ 
rate, free, first much longer than second, the latter scarcely longer than 
the fourth; a smaller oval inner and a much larger roundish outer me¬ 
tacarpal tubercle ; subarticular tubercles strong, subconical ; along the 
metacarpals some minute tubercles, viz. two on the first, second and 
third, but only one on the fourth metacarpal. Toes moderate, with a trace 
of fringe on each side ; subarticular tubercles as on the hand ; two meta¬ 
tarsal tubercles, the inner oval, slightly copressed, the outer smaller and 
round; along the metatarsals very distinct series of small tu¬ 
bercles* (pl. XIII, fig. 1 2). Tibio-tarsal articulation reaches the centre 
(£) or the anterior corner ( cT) of the eye.** Skin minutely gra¬ 
nulated between the ilia, stronger on the flanks to the discoidal fold 
and on the lower surface of the thighs. From snout to vent runs a fine, 
elavated middle line; from the posterior corner ot the eye two glan¬ 
dular folds arise, diverging on their commencement, afterwards running- 
parallel and extending to groin, the outer of which is several times inter¬ 
rupted and sends down a branch to the arm behind the tympanum ; bet¬ 
ween this lateral folds runs a row of more or less prominent longitudinal 
warts ; a distinct tarsal fold (pl. XIII, fig. 1% and a strong ventral 
discoidal fold. Male without external vocal sacs ; thumb without spine¬ 
bearing tubercles. 
Coloration. Female greyish olive above, along the elevated middle 
line of the head and back with minute black, behind white edged points 
and a few rather indistinct dark spots, more distinct between the ilia. 
Each lateral fold covered with longitudinal black spots, more or less 
confluent into a black stripe, which is margined with a fine white line 
above ; the longitudinal warts between the inner and outer lateral fold 
black, with white margins above or with dirty-white centres. Between 
the eyes a saddle-shaped dark spot, in front and laterally edged with a 
black line and the latter margined with dirty-white. A blackish-brown 
* Cope asserted: «Sole smooth», but Count Peracca, who had opportunity 
to compare his specimen in the British Museum, states as follows : — «pianta dei 
piedi non liscia (Cope) ma presentante una serie di tubercoletti conici smussati 
disposti su ciascuno dei quattro metatarsi.» 
** After Cope «The heel extended reaches the nostril», and this is in fact 
the case on Spix’s type.
