BARBOUR AND NOBLE: AMPHIBIANS FROM PERU. 403 



sheath in the adult; sacral diapophysis slightly dilated; no vomerine 

 teeth; tongue elliptic, narrow and free behind; pupil horizontal; 

 tympanum distinct; toes free; terminal phalanges T-shaped. 



Leptodactylidae. 



Eleutherodactylus lymani/ sp. nov. 



Diagnosis. Similar to E. conspicillatus (Giinther) in most of its features, 

 but differing from that species in the much shorter toes, especially the fourth 

 toe; in the longer first finger and in the somewhat different color-pattern. 

 Young specimens are similar in habit to that species but adult specimens are 

 much stouter and with a broader, less acuminate snout. 



Range. Hills and valleys of the central Andes of northwestern Peru, 

 from Palambla (near Huancabamba) to Bellavista. 



Tyjie. M. C. Z. 5,422 from Perico, valley of the Chinchipe, north- 

 western Peru; 10 September, 1916, G. K. Noble. 



Description of Type. Size large, head broader than body, exactly as long 

 as broad; snout subacuminate with distinct canthus rostralis and concave 

 loreal region; orbital diameter equals the distance between the eye and nostril, 

 twice as great as the distance from nostril to end of snout; interorbital space 

 a trifle broader than the upper eyelid. Tongue oval, slightly nicked behind. 

 Vomerine teeth in two oblique, approximated fasciculi behind the choanae. 

 Tympanum distinct, half the diameter of the eye. Fingers moderate, the first 

 extending beyond the second; toes short with a rudiment of a web; discs 

 small, not much wider than the middle part of the toes; subarticular tubercles 

 well developed; a round outer and an elongate inner metatarsal tubercle, both 

 very distinct. Tibiotarsal articulation reaches just to the tip of the snout. 

 Sk'in finely granular on the back, nearly smooth on the head, and coarsely 

 granular on the lower surfaces of the thighs; no glandular dorsolateral fold. 



Ground-color above, ashy grey fading to yellowish grey on the sides. Two 

 che\Ton-shaped bands of dark brown on the back, one over the scapulae and 

 one just before the ilia; two or three spots of the same color posterior to the 

 ilia. A narrow stripe of dark brown along the canthus rostralis and over the 

 tympanum; a faint interorbital bar. Lips and appendages cross-barred with 

 dark brown; four bars across the legs; posterior surfaces of thigh reticulated 

 with dark brown and white. Ventral surface of head and body white, un- 

 spotted; of feet a dark brown. 



1 Named in honor of Prof. Theodore Lyman whose generosity enabled the Museum of Com- 

 parative Zoology to send a zoologist with the Harvard Peruvian expedition of 1916.
