The proportions of the digits are as in A. punctatum. The longest finger is but one-third the fore-arui; the long- est toe is a little more than one third the leg from knee. The out- stretched hind legs are about two thirds the head and body to groin. AVhen the fore and hind legs are extended and appressed to the sides they are separated by six of the intercostal spaces. This indicates that the legs are shorter than in any other species of the genus. The tongue is thick, fleshy, and attached, although slightly free at sides and tip. There is a longitudinal gr()ove in the tongue, separating the two papillose portions, of an oval shape, placed side by side, with the edge of the tongue projecting beyond tiiem. The papilhe form parallel series in each oval oblique to the central groove. This is not found in Ambhj- stonui jeffersonianum. There are oidy two patches or lines of palatine teeth. These occupy the middle of the palate, forming an Ai the angle anterior and reaching as far forward as the anterior border of the inner nares. The postero- external ends do not pass the inner margin of those nares (in the soft palate, the proportions being a little difl'erent in the skull). Sometimes these two patches form nearly a straight line, or at least the central portion is straight, the lateral bending slightly Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Cope, E.
