The Tenth Report of the Peabody Museum is one of the most 
interesting in the series. We have already referred to Dr. Abbott’s 
paper. Those of Professor Andrews and Admiral F. Bandelier are 
worthy of careful study. 
Two articles have = dort in the New York Nation concerning 
the Nes Percés in the numbers for July 12th and August 2d. 
The same journal, Sépectibet 6th, treats of the Indian policy of 
Canada and of the United States. 
The archeological section of the Academy of Sciences at St. 
Louis, has published a caution to collectors against imitations of 
pottery, etc., from the mounds. The same difficulty has arisen in 
England and Germany with reference to antiquities within their own 
borders and from the East: notably, Flint Jack, the Shapira collec- 
tion of Moabite pottery, and the carvings from the Thurigen Cave, 
near Schaffhausen in Switzerland. Colonel Whittlesey has done 
good service in exposing frauds in hieroglyphics, and Mr. J. D. 
Moody of Mendola, Illinois, sends a pamphlet of four pages, 
attacking the authenticity of the Rockford Tablet. No one should 
be more zealous than the archzologists themselves in unearthing 
everything of the kind, since no amount of doubtful material will 
aid the truth in the least —O. T. Mason, Washington, D. C

THE SAURIANS OF THE Dakota Epocu.—Professor Cope has 
recently described two additional species of terrestrial saurians 
a the Dakota rocks of Colorado, which rival the Camarasau- 
rus supremus in dimensions. They are referred to a new genus 
= which resembles Camarasaurus in the chambered character of the 
vertebral centra, and in the peculiar interlocking articulation of — 
the neural arches, but differ from it in the amphiccelous character 
-of the centra and the form of the neural spine, which is longitu- 
dinal instead of transverse. The articulation of the neural arches 
alluded to is very peculiar, and is effected by the presence of a 
new vertebral element which Professor Cope calls a hyposphen. 
It is an inverted wedge which is attached to the posterior zyga- 
pophyses below them by a median vertical plate of bone. This 
plate enters a deep fissure between the anterior zygapophyses 
and it results that the latter are tightly embraced between the | 
posterior zygapophyses above, and the hyposphen below. This 
‘structure is the reverse of that of the zygosphen articulation. 
e new genus is called Amphicwlias, and the species A. altus 
and A. latus. The length of the femur of the former is six feet 
two inches, a little exceeding that of the Camarasaurus Supremus, 
but it is more slender. The elevation of a dorsal vertebra is three 
feet two inches. The A. /atus is characterized by robustness, as
