Cope.] ^3o [Nov. 17, 



the present collection a small specimen of only 13 mm. in length has the 

 entire superior surfaces of a bright violet, as in the specimen called muri 

 cinus ; but it presents no structural difference from the form habenatus, and 

 small examples of the form podiciferus. From Buenos Ayres ; No. 331. 



Hylodes stejnegerianus, sp. nov. 



Muzzle flat, canthus rostralis distinct, concave, extremely little promi- 

 nent. Nostril near the extremity and as far anterior to the eye as the 

 long diameter of the eye slit. This latter dimension equals the diameter 

 of the nearly round tympanic membrane. Integument of head smooth ; 

 that of back with a delicate median fold, and a fold on each side which 

 diverges at the scapular region and extends to the orbit. Parallel to the 

 laterodorsal fold is a dorsolateral fold on each side which terminates an- 

 teriorly near to the oblique fold just mentioned. Between these folds the 

 integument is tubercular. Sides and belly roughened with small tuber- 

 cles ; breast and throat smooth. Tongue longer than wide, pyriforra, 

 scarcely notched. Vomerine teeth in two fascicles well behind the cho- 

 anae, and farther apart than each one is within the longitudinal line of 

 the internal border of the nares. The heel of the extended hind limb 

 reaches the anterior border of the orbit. Width of head 2 3 times in 

 length of head and body. Digital enlargements small. 



Color above a dark bistre brown, with a pink band extending on each 

 side from the eye to the sacrum, passing above the tympanic membrane. 

 Posterior limbs blackish brown, except the inferior side of the femora, 

 which are a lighter brown. Fore limbs pink with brown cross-bands. 

 Belly dirty white, the breast and throat densely dusted with brown. 

 Head uniform blackish brown, with the exception that on the edge of the 

 upper lip there are three pairs of pale vertical bars which represent the 

 borders of three lip-spots.

It is only necessary to compare this species with the H. polypUicliusCoTpe 

 {Proceeds. Amer. Philos. Soc, 1885, p. 276) from Nicaragua. In this spe- 

 cies the top of the head and especially the eyelids are tubercular, while 

 they are smooth in the ff. stejnegerianus, and the integument generally 

 is covered with larger and more numerous warts. The muzzle is shorter
