Description of the type-specimen.— Cramsil ridges sharply defined 

 but not high, consisting of canthal, preocular, supraocular, postocular, 

 parietal, and supratympanic ridges, the supraocular ridge flatly 

 curved and forming a Y with the parietal ridges which converge back- 

 wards; snout prominent, overhanging the lip; nostrils anterior to 

 edge of lip; interorbital space nearly flat, much wider than the upper 

 eyehd; tympanum very distinct, much higher than wide, its greatest 

 diameter about two-thirds that of the eye; first fimger not extending 

 beyond second; toes about half webbed; three outer joints of fourth 

 toe free; subarticular tubercles single; two metatarsal tubercles, 

 inner one large, well developed ; tarsal fold only indicated by a series 

 of close-set spines; heels do not overlap; heel extending to anterior 

 border of eye; upper surfaces, including top of head, evenly covered 

 with small, subequal, spinose warts; underside covered with small, 

 densely set, high tubercles; parotoids large, about two-thirds the 

 length of the head, descending on the sides.

Remarks. — This species, of which the expedition brought home 

 only one specimen, resembles Bufo coniferus Cope, but has larger 

 parotoids and shorter legs, especially fore legs; the upper surface of 

 the body including head is evenly covered with small spinose warts, 

 and there are no cone-shaped spines on sides of neck and body; the 

 cranial crests are lower, those of the canthus rostraUs more straight 

 and distant; profile of snout much more projectmg, the nostrils 

 being situated anterior to the lip. 



From Bufo ocJcendoni Boulenger ^ (type-locality Marcapata Valley, 

 eastern Peru) the present species differs in the more projecting snout, 

 the very distinct tympanum, the large inner metatarsal tubercle, the 

 densely and uniformly spinose upper parts, and the larger parotoids. 



ELEUTHERODACTYLUS BINGHAMI, new species. 



Diagnosis. — Toes nearly free; belly granular; upper surface smooth; 

 head moderate, without bony ridges; vomerine teeth in two small 

 transverse series between or slightly behind the choanas; tympanum 

 distmct, about two-fi[fths or one-third the diameter of the eye. 



Habitat. — Peru. 



Type-specimen. — Cat. No. 49559, U.S.N.M.; Cuzco, Peru, about 

 11,500 feet altitude; July 9, 1911. 



Description of type-specimen. — Tongue large, rounded, entire 

 behind; vomerine teeth in two small transverse series between, or
