SPEC. CHAR. Subdigital disks small in both pairs of limbs. Green- 

 ish-brown, with a dorsal light line. Sides of abdomen and limbs 

 spotted with black. Beneath, dull-brown. 



S?x.ITalophila herot, GED. in Proc. Acad. Nat. Sci. Philad. VI, 1853, 423. 



OBSERV. A preliminary glance at the figure which represents this 

 species would leave the impression of a Cystignathus, or better, per- 

 haps, of a Leplodaclylus. The remarkable size of the species, its much 

 developed locoinotory organs, and the slenderness of the digits, all 

 contribute to the aspect just alluded to. The comparatively small de- 

 velopment of the terminal subdigital disks has also a good deal to do 

 with its general physiognomy. 



DESCR. The head forms more than the third of the length. It is as 

 long as broad, and, seen from above, it has a subtriangular shape, the 

 snout being but slightly truncated. Its upper surface is flattened ; 

 the phrenic region depressed or subconcave ; the canthus rostralis 

 almost even with the upper surface of the snout. The nostrils are 

 comparatively small, elongated, obliquely situated towards the upper 

 region of the snout, and close to its anterior declivity. Their distance 

 from the anterior rim of the orbits is twice that which extends be- 

 tween them and the margin of the upper jaw. The eyes are large, 

 prominent, subcircular ; their diameter being equal to the distance 

 between them and the nostrils, and which is quite considerable. The 

 interocular space is but two-thirds of the longitudinal diameter of the 

 eye. The tympanum is rather large and conspicuous, subcircular ; 

 a vertical line drawn through its middle would intersect the angle of
