It is wrong in Dumeril and Bibron to say that this species is a variety of H. 

 squirella. In shape and size the difference is most considerable. The latter 

 animal during the warm season is always to be met with about houses, the H. 

 femoralis never. Besides, their notes are entirely different.

Color varying at the will of the animal from green to brown of different 

 degrees of intensity, spotted and speckled irregularly with darker or dusky and 

 sometimes with paler, often however of a uniform color. A darker line extends 

 from the nostrils to the eyes and through them to the insertion of the arm (this 

 is sometimes evanescent) ; beneath this darker line extends a white one which 

 reaches nearly to the groin ; sometimes interrupted or broken into three or four 

 parts. The dark line on the vertex between the eyes never fails entirely, al- 

 though it is sometimes reduced to a rather large spot on each eyelid. Toes not 

 so much palmate as in the preceding species. 



H. delitescens. H. delitescens L. C. I. c. p. 181. Holbrook, 1. c. pi. 32. 



Variable at will from cinereous to brown, more or less distinctly spotted with 

 darker. Differs especially from the former in having a larger and blunter head. 

 The exterior portion of the thighs and the whole of the under side of the arms 

 and legs i3 yellow, the legs also are not barred, but varied and speckled with 

 darker, chin and throat smooth. Toes as in the preceding species. 



Inhabits Georgia. In the spring it is found very numerous under the bark of 

 dead trees. 



H. pickeringii. Hylodes Pickeringi Holbrook, 1. c. pi. 34. 



Above smooth, light-brown or fawn-color with lines and spots or specks of 

 dusky, the first of these most frequently arranged so as to form an oblique angled 

 cross, a line of the same color on the top of the head forming an angle pointing 

 backwards, and another extending from the nose to the insertion of the arm, 

 this last sometimes not apparent, indeed all the dusky marks are frequently so 

 indistinct as to be scarcely observable, beneath whitish granulate, arms and legs 

 marked with transverse bars of darker or dusky. 



This is a true Hyla and wot an Hylodes : it is never found in the water, but on 

 the leaves of plants and under the bark of dead trees. 



H. ocularis. H. ocularis Daudin, 1. c. p. 32. Hylodes ocularis Holbrook, 

 pi. 35. 



Above brown or bronzed or silvery grey, very finely speckled with dusky or 

 darker, a tolerably wide band of black proceeds from the tip of the nose to the 

 middle or beyond the middle of the sides, this is bordered beneath with white. 

 Chin and under side of the thighs speckled with black. Legs speckled like the 

 back and more or less spotted and barred with dusky, fingers and toes all fur- 

 nished with small disks. 



Length .6. 

 ^Inhabits Georgia. The smallest of all known Ranina. From the small size 

 of this and the preceding species, the web between the third and fourth toes is 

 not very perceptible. 



SCAPHIOPUS Holbrook. 



S. solitarius Holbrook, iv. pi. 27. 



Above olive brown, dusky, of various shades, with blotches of darker or black, 

 and two lines of pale yellow or whitish from the orbits to the vent, and some- 

 times another of the same color on the sides ; tympanum small, pale olive. Back 

 warty, the warts of different sizes and colors, some of them dark brown or 

 dusky, others orange colored or red. 



This curious animal so much resembling a frog in its maxillary and palatine 

 teeth, and a toad in its pnrotids, the form of its body and its subterranean life, 

 gives a fair example of some of our systematic arrangements. It has been 

 placed by M. Dumeril among the frogs, when to all intents and purposes it is
