FROGS OF COLOMBIA — COCHRAN AND GOIN 95 



detailed description states that the fingers are "webbed only a little 

 beyond the metacarpals, but the web extending into the metacarpal 

 region making the fingers appear about one-third webbed, the web 

 continued along the edges of the fingers as a narrow seam." This 

 "narrow seam" has been called the "lateral ridge" in the present 

 paper. Noble further states that the toes are "about three-fourths 

 webbed, the web extending to the end of the phalanx of the two 

 inner toes, to the base of the last phalanx of the third and fifth toes, 

 and to the base of the antepenultimate of the fourth toe; web continued 

 as a seam to the tips of all the toes . . . ." 



Noble believed that his rostratus was related to Bufo coniferus Cope. 

 When Myers and Leviton publish the results of their current studies 

 on coniferus and its allies, we shall have a broader conception of the 

 status of these toads. 



Specimens Examined 

 COLOMBIA 



Antioqtjia: Santa Rita Creek, 14 mi. north of Mesopotamia, AMNH 1359 

 (holotype), 1384 (paratype). 



Bufo rostratus nicefori, new subspecies 



Plate 15d-p 



Holotype. — USNM 163476, an adult from El Chaquiro, Antioquia, 

 collected by Hno. NicSforo Maria in December 1966. 



Paratypes. — MLS 449-52, same data as holotype. 



Diagnosis. — Snout bluntly pointed at tip and projecting; supra- 

 orbital ridges coarse and heavy, top of head between them appearing 

 concave. Tympanum hidden. Dorsolateral tubercles large and blunt, 

 extending to groin. Toes one-fourth to one-third webbed. Finger 

 short, heavy, distinctly webbed at base. Hind leg short, adpressed 

 heel reaching axilla or front of shoulder. 



Description of holotype. — A pair of heavy, nearly parallel crests 

 beginning between the eyes and continuing back on the parietal 

 region; tongue about half as wide as mouth opening, very elongate, 

 its posterior border free and unnotched; snout proboscis-like, the tip 

 elongate and rounded when viewed from above, bluntly pointed in 

 profile, lower surface of proboscis smooth and rounded, the upper 

 jaw extending well beyond the lower. Nostrils lateral, slightly pro- 

 jecting, their distance from end of snout equal to their distance from 

 eye. Canthus rostralis swollen, continuous with the rostrum; loreal 

 region weakly concave, sloping a little towards the upper lip. Eye 

 large, prominent, its diameter slightly less than its distance from tip 

 of snout; interorbital diameter twice that of upper eyelid, greater than 

 interval between nostrils. Tympanum covered. Fingers fairly short
