Archives; Discoveries in science. of the iiiitcrior aspects of the fore leg aud feiiiui- larger than the others; those of the tibia small, aud those of the posterior face of the feiimr still smaller. Scales of the tail in whorls of equal width. The scales of equal size aud all couvex in cross section, but not keeled. None of the scales of the body or limbs keeled. The nostril is situated in a small scute at the junction of the sutures which separate the internasal, rostral, first labial, and first loreal scuta. Three loreals, increasing in size posteriorly. A cir- cle of scales surrounds the eye, of which the supe- rior, or superciliary, are the largest. Tlie latter are separated by one row of scales from the parietal, frontoparietal, and frontal on each side. The fronto- nasal is nearly square. The internasals are con- siderably in contact. The frontal is hexagonal, and is broader than long. The interparietal is as large as each parietal. It is longer than wide, and notches the contact of the frontopari- etals. The occipitals are large and quadrate. A sin- gle large temporal bounds the parietals and occipital, and it is followed by two small scuta, which are in contact with the occipital. A triangular plate inter- venes between the occip- ital aud parietal. There are eight scales on the ui»per lip. Of these the fifth is the largest, and is i)art of an annulus which begins with two small scales at the posterior loreal and terminates at the seventh scale, opposite the middle of the pupil posteriorly. The posterior labials are small and are separated by nine rows of still smaller scales fron) the large temporal. No larg'e auricular scales. The eye is rather large, and its diameter is contained in the length of muzzle in front of it times. Tiie vertical diameter of the auricular meatus is a little less.
