 trale, recherches zoologiques, pt. 3, sect. 2, pp. 35, 36, pi. 12, fig. 1. 



Type locality. — Mexico. 



Range. — Unknown. 



Remarks. — This little tree frog is described as having the vomerine 

 teeth situated at the level of the anterior edges of the choanae. 

 This peculiarity alone distinguishes this species from all other known 

 Mexican hylas. The type (M.H.N.P. No. 380a, parchment label 

 No. 6317), according to the label was collected somewhere in Mexico 

 by Firmin Bocourt, and is described in my notes as follows: Head- 

 and-body length, 38.7 mm.; transverse diameter of tympanum, 2.4 

 mm.; transverse diameter of eye, 4.3 mm.; the hind limb being car- 

 ried forward along the body, the tibio-tarsal joint reaches to between 

 the eye and tip of snout; a tarsal fold; toes webbed to base of penulti- 

 mate phalanx; inner metatarsal tubercle distinct, outer one missing or 

 else very minute; no supernumerary tubercles on plantar surface of 

 foot; fingers free, no web at base; first finger shorter than second; 

 vomerine teeth in tvro transverse rows near level of anterior mar- 

 gins of choanae; coloration of upperparts apparently gj-eenish; under- 

 parts yellowish; a narrow light yellow stripe along can thus rostralis 

 from nostril to eye, and from posterior edge of upper eyelid backward 

 above tympanum, and then obliquely downward to middle of side; 

 this stripe seems to be the upper margin of a broad dark band that 

 extends obliquely downward behind the tympanum; throat, abdomen, 

 and under surface of thighs coarsely granulated. 



Specimens examined. — One, the type. 



HYLA STAUFFERI Cope 



1865. Hyla staufferi Cope, Proc. Acad. Nat. Sci. Philadelphia, vol. 17, p. 195, Oct. 



Type locality. — Orizaba, State of Vera Cruz, Mexico. 



Range. — Known to occur onl}^ at three localities in western Vera 

 Cruz — Orizaba, Potrero, and Motzorongo. 



Remarks. — This puzzling little tree frog seems to dift'er from Hyla 

 eximia in several respects. It has no tarsal fold, the loreal region is 

 more oblique, and the interval between eye and nostril is noticeably 

 greater than the transverse diameter of the eye. The original color 

 pattern of the type (U.S.N.M. No. 15317) has disappeared. Accord- 

 ing to Cope, the upperparts were originally dark olive, with inter- 

 orbital dark bar, a longitudinal black bar over each scapula, and an 

 indistinct dark stripe along the coccyx. An approach to this arrange-
