THE BATEACHIA OF NOETH AMEEICA. 359 



lakes of that region. In suck localities they can not have arboreal 

 habits, owing to the absence of treesj and it is probable that their 

 habits are like those of the Hyla picker imgii of the east. 



I append a description of the type specimen of the Hyla nebulosa 

 FTallowell (U. S. Pac. E. R. Survey Eept., 35th parallel, Eeptiles p. 21), 

 whicli I afterwards called H. cadaverina, owing to the pre-occupation of 

 Hallo well's name. The single specimen known is now in bad condition, 

 and I am not sure that it should not be referred to the H. regilla. The 

 description now given was taken from the specimen when nearly fresh. 



Size medium ; form stout; legs elongate ; head short, broad, breadth 

 less than three times in the total length ; muzzle rounded, little promi- 

 nent; canthus rostralis straight, elevated ; fingers free; toes two-thirds 

 webbed ; the digits short, stout ; the pallettes large ; a strong tarsal 

 wing or fold; eyes small; skin smooth. 



Femora unicolor behind ; no dark labial border or dark or light lat- 

 eral stripes ; color pale, with indistinct blackish dorsal spots. 



The heel of the extended hind limb extends to between the orbit and 

 the end of the muzzle; the largest digital dilatations equal the tym- 

 panum, which is indistinct and one-fourth the size of the eye. The eye 

 is smaller and less prominent than usual, its long diameter measuring 

 the width between canthus rostralis at orbits, one and one-third times, 

 and two-thirds length of the brachium. Foot one and three-fourths and 

 one and five-sixths breadth of head at canthus oris; vomerine* teetli 

 entirely between the nares, which appear larger than the ostia of the 

 Eustachian tubes. 



Sacral diapophyses elongate; triangles very narrow proximally ; 

 upper surface slightly convex, thus differing from the eximia, where they 

 are broader, flatter, and not so produced. Skin nearly smooth above; 

 abdominal areolations not extending on the sides ; a pectoral fold. Toes 

 stout, margined ; the dilatations large (not proportionally to the digits), 

 except on the thumb. 



Above gray, with an interocular and numerous dorsal irregular black- 

 ish spots. Canthus rostralis and band behind eye dark shaded ; lip and 

 prebrachial region light, dark punctulate. Limbs indistinctly cross- 

 barred; below yellowish, immaculate.

Var. laticeps Cope. 



Color much like that of var. Eegilla from Fort Tejon ; that is, a dark 

 interocular triangle and numerous well-defined dorsal spots. The broad
