supernumerary tubercles on plantar surface of foot; first finger longer 

 than second; a broad white streak extends backward from tip of 

 snout above brown upper lip and below eye and tympanum to fore 

 limb; lower lip variegated with light and dark; fore limb with dark 

 cross bands; upper surface of thigh and tibia with indistinct dark cross 

 bands; an exceedingly fine vertebral dermal ridge; skin of upper- 

 parts with tiny asperities and small glandular elevations; a short 

 curved dermal ridge along vertebral margin of scapula; can thus ros- 

 tralis rounded; vomerine teeth in two oblique posteriorly converging 

 rows behind and within level of choanae. 



B.M. No. 1903. 9. 30. 237: Head-and-body length, 23.2 mm.; trans- 

 verse diameter of tympanum, 2.7 mm.; transverse diameter of eye, 

 2.8 mm. ; anterior edge of eye to nostril, 2.8 mm. ; the hind limb being 

 carried forward along the body, the tibio-tarsal joint reaches beyond 

 end of snout; a distinct crested tarsal tubercle about midway; super- 

 numerary tubercles on plantar surface of foot; coloration the same as 

 in the preceding, except that lower lip is brown and not variegated 

 with a light color; can thus rostralis rounded; vomerine teeth similar 

 to the other cotype.

1922. Eleutherodactylus dunnii Barbour, Proc. Biol. Soc. Washington, vol. 35, 

 p. Ill, Oct. 17. 



Type locality. — Cerro de los Estrapajos, somewhat west and a little 

 higher than the city of Jalapa, State of Vera Cruz, Mexico. 



Range. — Evidently restricted to a limited district in western Vera 

 Cruz. 



Remarks.— Dt. E. R, Dunn collected two specimens at the type 

 locality and a third from the near-by village of Xico. This species

 granular and studded with scattered tubercles. The texture of the 

 skin seems to be the diagnostic character. It is unquestionably closely 

 related to E. rhodopis and for the present is recognized as a distinct 

 species. The acquisition of an adequate series of specimens of both
