96 ON THE BATRACHIA AND REPTILIA OF COSTA RICA. 



have been the objects of study by M. Bocourt of Paris, Peters of Berlin, Giintber 

 of London, and Keferstein of Gottingen. The explorers who have furnished the 

 material to these herpetologists have been Messrs. Hoffmann, Salvin, and Seebach. 

 The total number of species known from the investigations, now amounts to 

 one hundred and thirty-two. But many species have been described from the 

 adjoining states of Nicaragua and Chiriqui, and from Veragua, adjoining the 

 latter, of which many will be found to enter Costa Rica also. Thus it is evident 

 that this region is very rich in terrestrial cold-blooded vertebrata. The State of 

 Costa Rica is about equal in extent to that of South Carolina.

GYMNOPHIONA. 



1. Siphonops mexicanus, Dum. Bibr., viii. 284. 



From the forest country near the coast at Limon. 



URODELA. 



2. OpHEOBATRAcnus vermicularis, Gray, Ann. Mag. Nat. Hist. 1868, 297. (Edipina uniformis, 



Keferstein, Archiv. fiir Naturgesch., 1868, 299. 



Three specimens, one from the Pico Blanco, at 6000 feet elevation, of large size, 

 measuring m. .162 in length. The cranium of this one is completely ossified above, 

 but the choanse are not isolated, but open into the orbit by a wide fissure. The 

 two other specimens are from the lower country, twenty miles from the coast. 



3. CEdiptjs morio? Cope, Proc. Academy Philadelphia, 1869, p. 103. 



A partly preserved specimen from the eastern slope of the Pico Blanco. 



ANURA. 



BUFONIFORMIA. 



4. Cranopsis fastidiosus, Cope, gen. et sp. now Bufonidarum. 



Char. Gen. — No ostia-pharyngea nor tympanum ; no vomerine teeth. Cranial 

 integument entirely occupied by a rugose ossification ; parotoid glands present. 

 Fingers and toes distinct, the latter palmate. 



This genus is Peltaphryne, Cope, with the auditory apparatus wanting. Char, 

 spec. — Size of the Bufo lentiginosus. The head wide, not depressed, the cranial 

 ridges consisting of elevated canthus rostralis, supra- and post-orbital border and 

 a supra-tympanic crest extending to the parotoid gland. These, especially the 

 last, are obtusely thickened. The supra-tympanic crest is produced downwards
