Type locality. — Mexico. 



Range. — Western side of the Mexican Plateau from Zacatecas south- 

 ward through Jalisco and Oaxaca to the Isthmus of Tehuantepec. 



Remarks. — An examination of the type of Leuiperus mexicanus 

 (M.H.N. P. No. 226a, parchment label No. 6318) convinced Dr. E. 

 R. Dunn that Parker had erred in referring it to the genus Pleurodema 

 and that this species was the same as Giinther's Hylodes calcitrans 

 from western Mexico. In commenting upon this species Parker 

 stated that: 



No specimens of this species have been examined, but it has been referred to 

 this genus rather than to Physalaemus on account of the absence of any tarsal 

 tubercle; its real position is still uncertain. Known only from the type speci- 

 mens from Mexico. 



Adolphe Boucard is listed as the collector of the type of Leuiperus 

 mexicanus in the catalogue of the Museum National d'Histoire Natu- 

 relle, Paris. The following notes were made on this specimen: 

 Head-and-body length, 39 mm.; the hind limb being carried forward 

 along the body, the tibio- tarsal joint reaches to or slightly beyond 

 tip of snout; no tarsal fold; plantar surface of foot without super- 

 numerary tubercles; small inner and outer metatarsal tubercles; 

 faint black crossbars on hind limbs; vomerine teeth in two minute 

 clusters between the choanae; first finger longer than the second. 

 It is clearly a member of the genus Eleutherodactylus. 



Brocchi's Hylodes lineatus seems to have been a rose-gray individual 

 with very narrow vertebral stripe, and in so far as color is concerned 

 it is not unlike other specimens taken in the State of Oaxaca. Al- 

 though a rather thorough search was made in the catalogues of the 

 laboratory of herpetology of the Paris Museum, no entry of a Hylodes 

 from Attitlan was found.
