THE Green Snake IN New Mexico. — It may be interesting to 
mention an increase of geographical range for the common green snake 
( Cyclophis vernalis). It was found in 1874 at Abiquin, New Mexico, in 
the valley of the Chama, by Dr. O. Liew, and in 1875 by Lieut. W. L. 
Carpenter, U. S. A., in Moreno Valley, Northern New Mexico, and 
again at the head of Ponil Creek, Northern New Mexico. Lieutenant 
Carpenter also states that the species is by no means uncommon in 
Southern Colorado, — H. C. Yarrow.

NOTES on THE STONE IMPLEMENTS FROM ARKANSAS, AT THE PHIL- 
ADELPHIA EXHIBITION. — In the building erected by the State of Ar- 
kansas for the purpose of exhibiting the various resources of that com- 
monwealth is a small but very beautiful series of stone implements, all 
of which, as I was there informed, were taken from various mounds in 
Garland, Montgomery, and Saline counties. While the various common 
forms of implements are all represented by excellent specimens, there 
is a noticeable preponderance of certain patterns which in other local- 
ities are less abundant than allied forms. For instance, the polished 
celts, of sizes suggesting the ax, rather than a skinning knife, are 
numerously represented, while but few specimens of the more common 
grooved ax are in the collection. Whether this preponderance of large 
celts, as compared with grooved axes, obtains throughout the territory 
from which these specimens were brought, I could not learn. Certainly, 
in the Eastern and Middle States the grooved axes are more abundant 
than celts of the same average size. The spear and arrow points are 
represented by a series which for beauty of material — they are all 
chipped from novaculite— and delicacy of workmanship » far surpass 
any similar forms that I have seen. This perfettion of the art of flint- 
chipping is alike in the spear-heads, six and eight inches in lengt.

The pestles are all cylindrical, and not with a flaring end, as is common 
to this form of implement in many localities. Of rade implements but 
few specimens are shown, and none with that weathering of the surface
