152 PROCEEDINGS OP THE ACADEMY OF 



the body; muzzle prominent, rounded. Tympanic disc round, half the size of 

 the eye. Nostrils lateral, internal nares large, equal to ostia of eustachian 

 tubes. Behind these are placed the two curved series of vomerine teeth, which 

 extend nearly from the maxillary wall ; their inner extremities are directed 

 backwards, and are separated by a slight interval. Tongue elongate oval, 

 entire. Without granulations above, below, or upon the sides. Pallettes 

 moderately developed. Palms tuberculous; three warts in the posterior series, 

 of which the median is much the largest. Soles with small tubercles, two 

 small posterior metatarsals, the inner elongate, acute. Heel reaching orbit, 

 when directed forward. Length of head and body 1 in. 6 1. Hinder ex- 

 tremity 1 in. 11 1. Tarsus, to end of digit, 1 in. 1 1. Antebrachium 4J 1. 



Beneath whitish, immaculate. Above dark chestnut, a light band on each 

 side from posterior margin of the orbit to crural region ; between these, on the 

 vertex, the sides and extremities, the ground is coarsely marbled with whitish 

 or yellowish. 



Habitat. St. Thomas. Mus. Smithsonian. Ruse Coll. 



This species differs from its near ally, the martinicensis, in the greater 

 length of the series of vomerine teeth and in coloration. The posterior ex- 

 tremities are much shorter than in the d i m i d i a t u s. 



Hylodes auriculatus. 



Size small: head as wide as, or wider than, the body. Muzzle rounded. 

 Nostrils lateral. Tympanic disc circular, one-fourth the size of the eye. 

 Tongue elongate, obcordate, with a small emargination. Vomerine teeth in 

 two oblique series, which commence opposite the inner margin of the posterior 

 nares, and converge posteriorly, though the extremities are widely removed. 

 Above sparsely rugose; belly and femora beneath, granulate. Digital pallettes 

 well developed. Anterior extremity reaching to groin. Heel nearly to end 

 of the muzzle. Total length 10 1. Hinder extremity 1 in. 3 1. 



Above light gray, loreal region black; a black line descends from orbit to 

 near the shoulder, which crosses the upper part of the tympanum. A blackish 

 band between the eyes, a chevron-shaped one between the scapulas. Hinder 

 extremities dark, shaded on their posterior faces. Beneath yellowish, mental 

 and lower labial region varied with brown. 



Habitat. Eastern Cuba. Mus. Smithsonian, (No. 5207.) Philadelphia 

 Academy. 



This species is allied to H. martinicensis, but has a broader head, 

 longer extremities, and rougher skin : it is also much smaller. 



Hylodes cuneatus. 



Hyliform : head large, broader than the body. Muzzle elongate, acute. 

 Tympanic disc round, half the size of the eye. Internal nares smaller than 

 eustachian ostia; the latter are transverse. Vomerine teeth in two curved 

 series, which begin opposite, and much behind the external border of the in- 

 ternal nares, and converge posteriorly, leaving an interval. Tongue elongate 

 oval, rounded posteriorly, slightly nicked. Skin of the superior surfaces, ex- 

 cept that of the muzzle, granulated; beneath everywhere smooth. A slight 

 dermal fold extends from the end of the muzzle to the end of the coccyx, and 

 another, very delicate, commences behind each orbit, and descends upon the 

 side, then ascends towards the iliac region. Palm tubercular, two large meta- 

 carpal tubercles. Sole smooth, two metatarsal warts, the external not promi- 

 nent. Heel extending nearly to extremity of muzzle. Length of head and 

 body 1 in. 1 1. Hinder extremity 2 in. 6 1. Width of posterior gular re- 

 gion 1 1. 



Above blackish gray. Muzzle lighter as far as the abrupt commencement of 

 the darker between the eyes. A light line, from anterior border of orbit to 

 labial commissure, and one from the posterior border to the tympanum. A light 

 band from each supercilium to the coccygeal region. Extremities indistinctly
