9. Leptodactylus rubido. 



Gnatliophysa rubido, Cope, Proc. Ac. PUlad. 1874, p. 128. 



Tongue oval, slightly nicked behind. Vomerine teeth iu two 

 short arched series behind the choanse. 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 glandulat mass extending from near 

 the axilla to the groin, and occupying the width of the side. Red- 

 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. pentadactylws, 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.

10. Leptodactylus poecilochilus. 



Rana pachypua, juv., JSpix, Test. Pan. pi. 3. f. 1 



Oystignathus poecilochilus, Cope, Pi-oc, Ac. Philad. 1862, p. 150. 



Tongue oval, nicked behind. Vomerine teeth in two arched 

 series behind the choanee. 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 tubercles much developed ; 

 two metatarsal tubercles, the outer sometimes indistinct. The
