velopment, especially the second frenal ; scales upon back broader than in 

 Blandingii ; color olive above, black spotted without any distinct dorsal or 

 lateral vittae ; abdomen greenish with a tinge of yellow, immaculate ; the green 

 much more marked upon the sides ; 33 rows of scales, tricarinate upon back and 

 sides; total length 5 inch. 4 lines; from extremity of snout to anterior extremity 

 1 inch ; between anterior and posterior extremities 1 inch 4 lines ; of tail 3 

 inches ; (renewed) of anterior extremity to extremity of longest finger 10 lines ; 

 of posterior to extremity of longest toe 1 inch 1 line. 



Habitat. Liberia. One specimen presented by Dr. "William Blanding, per- 

 haps a variety of Blandingii. 



EUPREPES ALBILAHKIS, nob. 



Char. Supero-nasals not contiguous, inter-nasal much broader than long, 

 fronto-nasals in contact, more extended laterally than longitudinally; fronto- 

 parietal very narrow anteriorly ; scales 3-keeled ; color olive, black spotted, a 

 black irregular band passing from behind the eye along the sides, margined in- 

 feriorly with white; upper lip white; under parts bluish mingled with green 

 upon the abdomen ; chin yellowish. 



Description. This specimen is much smaller than any of those of Blandingii, 

 and differs from them all, even the young, in a marked manner, both in the 

 shape of the cephalic plates and in the coloration. The rostral plate presents 

 nothing remarkable, the supero-nasals are narrow, situated obliquely, a short 

 distance apart; the inter-nasal is hexagonal, much broader than long, with 

 an obtuse angle posteriorly, its lateral margins quite short; the fronto-nasal 

 are closely in contact (separate in Blandingii), and are shorter and more ex- 

 tended transversely than ia the latter species ; the frontal is quite narrow pos- 

 teriorly, presenting an obtuse angle in front ; the fronto-parietal differ much in 

 appearance from those of Blandingii, theiranteriorextremitiesbeing very narrow 

 and their lateral margin longer ; the inter-parietal is quite slender posteriorly, 

 with a moderately acute angle posteriorly ; there are eight supra-labials, the 

 sixth long and quadrangular (fifth in Blandingii), and situated immediately be- 

 neath the eye ; twelve transverse rows upon the back counting from one white 

 lateral margin to that on the opposite side. 



Coloration. Bronze or olive above, with irregular black spots ; a black band 

 from posterior margin of orbit, broad and well defined upon temples, more 

 narrow upon sides where it appears to be lost near the middle, with an irregular 

 margin superiorly, bordered with white inferiorly ; upper lips white ; under 

 parts bluish mingled •with green upon the abdomen ; chin with a tinge of 

 orange. 



Dimensions. Length of head 9 lines ; greatest breadth 3 ; length from head 

 to vent 13J lines; between anterior and posterior extremities 8}; from snout 

 to anterior extremity 6} ; arm 2 lines ; forearm 2 ; palm to tip of longest finger 3 ; 

 of thigh 2^; of leg 2; of sole to extremity of longest finger, 4^ lines, (tail 

 mutilated.) 



Habitat. Gaboon. One individual presented by Ford. 



A single specimen of a Scincoid described in Vol. VI. of the Proceedings 

 of the Academy, p. 64, under the name Acontias elegans, biit much larger, and 

 which evidently belongs to a genus distinct from Acontias. This specimen 

 measures 8 inches and 8 lines in extent, the tail 2 inches 10 lines, circumference 

 1 inch 3 lines. There are twenty-two transverse rows of scales, and one hun- 

 dred and seventy-three longitudinal, including fifty-six upon the tail ; there are 

 no eyelids, but the eye may be distinguished situated near the middle of a scale 

 at its anterior margin. The Typhline of Cuvier, from the Cape of Good Hope, 

 the only species of Typhline described by Dumeril and Bibron and by Mr. Gray, 

 is represented by the former to be without other cephalic plates than that which 

 encloses the whole face, as in a sort of case, (etui,) Mr. Gray, however, mentions 

 1857].
