NORTH AMERICA. 



BY LEONHARD STEJNEGER. 



[Published by permission of the Secretary of the Smithsonian Institution.] 



A very interesting addition to the fauna of the United States 

 was found in a recent collection kindly presented to the National 

 Museum by Mr. R. D. Camp. It is a small species of the 

 Mexican genus Syrrhophus, already represented in Texas by the 

 type species Syrrhophus viarnockii Cope, the original specimens 

 of which came from near San Antonio. These Leptodactylid 

 toads differ from Eleutherodadylus and Lithodytes in the absence 

 of vomerine teeth. 



Syrrhophus campi new species. 



Diagnosis. — Heel of extended hind leg reaches center of eye; diameter 

 of tympanum slightly more that half that of eye ; back coarsely granular ; 

 head wide. 



Type— v. S. Nat. Mus. Cat. No. 52,290; Brownsville, Texas ; R. D. 

 Camp, collector. 



Description of type-specimen. — Tongue broadly pear-shaped, somewhat 

 truncate behind with a tendency to a posterior lateral projection on each 

 side ; nostrils much nearer the tip of snout than the eye, their distance 

 from the latter slightly less than the eye diameter and equal their distance 

 from each other; upper eyelids much narrower than interorbital space 

 which is wider than diameter of eye; tympanum distinct, circular, its 

 rim interrupted above, slightly more than half the diameter of eye, 

 distance from the eye one-third its own diameter; fingers with well- 

 developed terminal disks which are truncate anteriorly; subarticular 

 tubercles very strongly developed; palms strongly tuberculate; second 

 finger scarcely longer than first; toes with considerably smaller disks; 

 soles with small tubercles; both inner and outer metatarsal tubercles 

 present and well developed ; no tarsal fold ; the bent limbs being pressed 

 along the side, knee and elbow overlap; hind limb being extended along 

 the side, heel reaches beyond posterior angle of eye; hind limbs being
