THREE NEW NEOTROPICAL SALIENTIA. 

 BY THOMAS BARBOUR. 



During the summer of 1921 Dr. E. R. Dunn was, as usual, 

 engaged in field work for the Museum of Comparative Zoology. 

 During a journey in Mexico, he found the first two novelties dis- 

 cussed herewith, while the third is from another source which 

 has been ever helpful in building up our representation of South 

 American amphibians, and reptiles as well. 



Eleutherodactylus dunnii, sp. nov. 



Type M. C. Z., No. 8242, from Cerro de los Estrapajos, somewhat west 

 and a little higher than the city of Jalapa, Mexico. E. R. Dunn, collector, 

 August, 1921. A second specimen from the type locality and a third from 

 the village of Xico nearby. 



Description. — Tongue narrow, oval, slightly nicked behind; vomerine 

 teeth in two short, heavy, oblique series some distance behind the chonae; 

 these two sharply converging series do not meet by a considerable space, 

 the interval separating them being about equal to the distance of the upper 

 end of each series from the nearest choana ; nostril much nearer tip of snout 

 than eye, its distance from the eye being greater than the diameter of the 

 latter; upper eyelid nearly as wide as interorbital space; tympanum large, 

 round, well defined, considerably over half the diameter of the eye, its dis- 

 tance from the eye being just over one-half of its own diameter; fingers with 

 tips undilated, first and second fingers equal in length; toes without apical 

 dilatation, two metatarsal tubercles, the outer round and conical, the inner 

 oblong and much more prominent; a rather indistinct tarsal fold; the hind 

 limbs being extended along the side, the heel just reaches beyond the tip 

 of the snout, the hind limbs being placed vertically to the axis of the body; 

 the heels overlap considerably ; skin above with finely scattered granules on 

 back, a faintly defined granular ridge down the middle of the back, belly 

 smooth with a strong discoidal fold and thighs heavily granulate. 

 Dimensions. — Tip of snout to vent 35 mm. 



Width of head 14 mm. 



Diameter of eye 4.4 mm. 



Tympanum 2.8 mm. 



Fore leg from axilla 23 mm. 



Hind leg from vent 67 mm.
