VOL. III.] Additions to Mammal Fauna. 201 



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 ( Sagit- 

 iaria) 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 probablv 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. yy 



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.
