These two were made of the same material and in the same manner 
as the artificial stones and were too frail to be used in the way Mr. 
- Henshaw mentions in ‘‘ Perforated Stones from California,’’ Bureau 
of Ethnology, 1887. 
A stone digging tool was found which was chisel-shaped at one 
end, was about sixteen inches long and about two inches in diameter. 
It must have been very useful in digging the Tule potato (Sag7#- 
_ taria) which is now sometimes called ‘‘ China potato,’’ which grew 
and still grows in abundance along the sloughs and in the extensive 
tule marshes of the vicinity. 
The obsidian spear and arrow-heads found here were fine examples 
of aboriginal skill. Two obsidian crescent-shaped knives or im- 
plements, which had probably been used in dressing fish, had their 
convex edges squarely notched or blocked. They are or were on 
exhibition in the Smithsonian building in 1882, and differ from any- 
thing I have seen elsewhere. 
The burial ground appears to have once been the site of an Indian 
village, as bones of elk, deer, fish, ducks, geese, and other birds are 
plentiful. A circular, saucer-shaped excavation for a fandango or . 
sweathouse, is additional evidence that a village once occupied the 
spot. Many of the skeletons which appear to have been buried 
last, and about the same time, were probably victims of small-pox 
or some other epidemic. 
Waves from passing steamboats have washed away a consider- 
-able part of the ground, and a large levee has recently been built 
on and of the mound. 
RECENT ADDITIONS TO THE NORTH AMERICAN 
LAND MAMMAL FAUNA. 
BY WALTER E. BRYANT. 
For several years I have been keeping a list of the new species 
of North American mammals as the descriptions appeared, with 
notes on the changes of nomenclature, for convenience of refer- 
ence. Since 1884, when Mr. True published “A Provisional 
List of the Mammals of North and Central America, and the West 
Indian Islands” (Proc. U. S. Nat. Mus. 1884, Appendix), I believe 
_ nothing has appeared in that line. Certainly the nomenclature of 
_ the class is in need of revision, and I am informed that an author- 
ity has in preparation some work of the kind.
