uriautly. On the sides of the ravines where moist, Zamias and short tree- 

 ferns, with other tropical phxnts, abound, and in their bottoms, innumer- 

 able Cactacege, Agaves and Tillandsite are growing in a state of nature ; 

 and oranges, bananas, Erythrinas, are cultivated. The reptiles of the 

 following catalogue were nearly all taken on the high country, the only 

 exception I know of being the Syrrhophus, which came from the bottom 

 of a ravine about two thousand feet below the general level. 



Batrachia. 

 Syrkhophus verrucipes, sp. nov. 



Posterior limbs of moderate length, the heel reaching to the anterior 

 edge of the eye. The toes of moderate length, with small pallettes, but 

 the anterior a little larger, and with prominent warts below, which are 

 especially large at the ends of the metapodial bones. One large palmar, 

 and two small solar tubercles. Skin everywhere smooth except on the 

 sides, which are tubercularareolate. No abdominal or gular fold. Head 

 flat above, moderately wide, with muzzle slightly prominent, vertical 

 loreal region, and obtuse canthus rostralis. Tympanic membrane more 

 than two thirds diameter of eye-slit. External nares almost at extremity 

 of muzzle ; internal nares larger, and so widely separated as to be par- 

 tially lateral in position. 



Color above dark bluish gray, marked with numerous black spots with 

 ill-defined borders. Limbs similar, with black cross-bands, which continue 

 on the external digit of each foot. Uppfer surface of femur, with close 

 white spots on a dark ground ; posterior face dark, with a few small white 

 spots. Edge of lip with a few light spots. Inferior surface white, un- 

 spotted. 



Length of head and body, .036 ; of head to line connecting ricti oris, 

 .008 ; length of fore limb, .018 ; of posterior limb, .039 ; of posterior foot, 

 .018 ; of tarsus, .008 ; width of head behind, .009. 



This species is well marked by its proportions and its color. Its legs are 

 longer and the tympanum is larger than in the -S^. marnocMi of Texas, 

 which it slightly resembles in color. I found it in the bottom of a rocky 

 gorge of a stream near its junction with the San Miguel river, at a depth 

 of at least 1800 feet below the level of the town of Zacualtipan. 



The Phyllohates bicolor, type of that genus, has narrow lateral nasal 

 bones, as in Elosia. In Syrrhophm they are as in Ilylodes. The Phyllo- 

 hates with areolated bellies, form, I think, a separate genus, for which I 

 propose the name Hypodiclyon ; type H. Helens {Phiillohates ridens Cope) • 

 Other species are II. verruciclatus and U. chalceus of Peters. 



There is a tree-frog, hitherto referred to Hyla, which is peculiar in 

 having the glandular areolation, which is confined to the belly in all other 

 species, extended over the dorsal region as well. This is the Hyla gratiosa 

 of Leconte of Florida and Georgia. On this account I propose to refer 

 this to a new genus under the name of Epedaphus.
