13. LEPTODACTYLUS. 243 
9. Leptodactylus rubido. 
Gnathophysa rubido, Cope, Proc. Ac. Philad. 1874, p. 128. 
Tongue oval, slightly nicked behind. Vomerine teeth in two 
short arched series behind the choanee. Snout-short, rounded; tym- 
panum scarcely more than half the width of the eye. Toes not 
fringed. The hind limb being carried forwards along the body, the 
tibio-tarsal articulation falls short to the orbit. Dorsal surface 
smooth, pustular between the ilia; a glandular lateral fold from 
the eye to near the groin ; another, just below it, extending to the 
middle of the side; a lateral glandular mass extending from near 
the axilla to the groin, and occupying the width of the side. Ted- 
dish brown or bright red above; a narrow black bar from nostril to 
tympanum ; upper lip broadly black-bordered ; hind limbs black, 
cross-barred ; hinder side of thighs faintly pale marbled; a few 
black spots on the groin ; inferior surfaces dark brown, with nume- 
rous pale dots, which may. be wanting on the gular region, and 
inosculate on the femur. Male with two spur-like tubercles on the 
inner side of the first digit; another, tricuspid, on each side of the 
breast. 
Allied to L. pentadactylus, but much smaller. 
Moyabamba, Peru. 
The following specimen, though differing in some respects from 
the above diagnosis, must, I think, be referred to this species. The 
differences are :—The tympanum is two thirds the diameter of the 
eye; there is no second fold below the dorso-lateral, and the lateral 
glandular mass is much smaller, and rendered besides rather indis- 
tinct by the smooth state of the specimen. The coloration is very 
handsome. ‘The hind part of the head and the back between the 
lateral folds vinaceous red; a dark-brown bar between the eyes ; 
the space between the canthal and labial streaks beautiful rose ; 
the hind limbs blackish brown, the hinder side of the thighs and the 
inner side of the calves with regular round white spots ; lower sur- 
faces brown, white-spotted.

Rana pachypus, juv., Spiv, Test. Ran. pl. 3. £1 
Cystignathus peecilochilus, Cope, Proc. Ac. Philad, 1862, p. 156. 
Tongue’ oval, nicked behind. Vomerine teeth in two arched 
series behind the choane. Snout acuminate, moderately prominent, 
longer than the greatest orbital diameter ; nostril a little nearer 
the tip of the snout than the eye; interorbital space as broad 
as the upper eyelid; tympanum nearly two thirds the width 
of the eye. Fingers moderate, first much longer than second; 
toes moderate, not fringed ; subarticular tuberclesa@iruch developed ; 
two metatarsal tubercles, the outer sometimes indistinct. The
