MEXICAN TAILLESS AMPHIBIANS 129 



Remarks. — The present location of the type of this species is un- 

 known. It is possible that it may be found in the Academy of 

 Natural Sciences of Philadelphia along with other types from Cope's 

 collection, since it formed part of a small collection made by Cope 

 and Dr. Santiago Bernad. No specimens referable to this species 

 were found in any American institution. 



Specimens examined. — None. 



SYRRHOPHUS VERRUCULATUS (Peters) 



1870. PhyUobates verruculatus Peters, Monatsber. k. preuss. Akad. Wiss. 

 Berlin, p. 650, Aug. 



Type locality. — Huanusco [==? Huatusco, State of Vera Cruz, 

 Mexico]. 



Range. — From the Rio Necaxa in northeastern Puebla southward to 

 central Vera Cruz (? Huatusco). 



Remarks. — It seems quite probable that some mistake in the original 

 label or in the printing of the description led Peters to publish 

 Huanusco as the type locality. No place name with this spelling was 

 located on any of the Mexican maps, and it would appear that Huat- 

 usco in Vera Cruz was the intended locality. 



The genus Hypodictyon was proposed by Cope in 1885 for species 

 with an areolated abdomen. Peters's verruculatus was one of the three 

 species mentioned as possessing this character. A reexamination of 

 the cotypes of cystignathoides shows that they likewise have an areo- 

 lated abdomen and this condition also exists in guttilatus. Faulty 

 preservation may account for some of the differences noted. On the 

 basis of available material it would seem that this areolated condition 

 of the skin is of little significance. 



The type of PhyUobates verruculatus (M.N.B. No. 6957), according 

 to Doctor Dunn, has a large tympanum with a black mark over it, 

 no distinct terminal disks, heavy subarticular tubercles, no vomerine 

 teeth, and a parotoid gland. The lumbar gland is not present. A 

 specimen in the British Museum (No. 1906. 6. 1. 100) from Buena 

 Vista, Guerrero, is referred to this species by Dunn. 



Specimens examined. — One (U.M.U.M. No. 2), collected at Necaxa, 

 Puebla, July 5, 1926, by H. B. Baker. 



Family HYLIDAE Gunther 



1858. Hylidae Gunther, Catalogue of the Batrachia Salientia in the collection 

 of the British Museum, p. 96. 



Tropical forests must have tree frogs, according to Dr. Hans Gadow, 

 and in each region these are fashioned from the nearest available 

 material. In Mexico, most of the frogs that hve in the trees belong 

 to the family HyHdae, but elsewhere in Central and South America, 

 as well as in Mexico, there are a number of less closely related frogs
