subject of a comparative study by MM. Alix and Bouvier. 
These naturalists became convinced that the animal belongs to a 
species distinct from the G. savagez, which they named in a com- 
munication to the Academy of. Sciences, G. mayema. Its prin- 
cipal characters are seen in the spines of the anterior cervical 
vertebra, which are much less elevated than in G. savaget, and in 
the greater approximation of the orbits, and prominent acute 
ridge of the middle line of the interorbital region. The species 
is smaller than the gorilla, about equaling the chimpanzee. 
Various other characters are mentioned by MM. Alix and Bou- 
vier, the value of which is as yet uncertain. The cranial crests 
are highly developed. i edad specimen was obtained on 
the coast of Quilo in Cong 
THE HERPETOLOGY OF Ney GuinEA.—Dr. H. E. Sauvage has 
recently given in Bulletin of the Société daa of “Paris, 
a list of the reptiles of New Guinea known up to the present 
time. He enumerates of Zestudinata, 3 Spede es; of Lacertilia, 
46 species, a among the families as follows: Gecconide, 12; 
Agamide, 6; Varanide, 5; Scincide, 23. Of Ophidia there are 
34 species, divided as follows: : Scolecophidia, 2; Peropoda, 6; 
Colubroidea, 17; troteroglypha, 9. The most noteworthy facts 
are: First, the absence of Solenoglyph peas as in Con 
(See Proceedings Academy Nat. Sciences, Philadelphia, 1859 
Acanthophis). second, the genera Erebophis and Sae Bie 
the latter resembling some of the Boidæ in several respects. 
Third, the large number of Scincidæ, and (W) esie (5) the 
presence of. Platemys as in Austral ia—&. D 
A Monstrous Froc.—Mr. Jacob Stauffer, be veteran naturalist 
of Lancaster, Pa., sends me a drawing of a frog (Rana palustris) 
with a well developed extra hind limb or what appears from his 
drawing and description to be, speaking more correctly, a united 
pair of hind limbs, though occupying an asymmetrical position, 
and having their true homologies to a certain extent concealed 
from this cause. A sketch and remark of Mr. Stauffer’s, how- 
ever, show the true nature of this limb to be compound. that is, 
the same color Aone and below, whilst the other or normal legs 
are of a dirty yellowish color beneath.” He further says this leg 
has six instead of five toes, and gives a sketch which leads me to 
think that the digital formula of the compound foot must be — 
written in this manner: 5, 4, 3, 3, 4,5. S showing clearly that the | 
limbs are fused together by their inner faces, thus bringing the 
outer or fourth and fifth toes to the outside, whilst the prevalence S 
of the superior and outer dark colors, and concealment of the 
inner and inferior yellow tints, is just what ought to oor woo
