346 Aboriginal Sheil Money. [June, 
that the word uAllo is corrupted from the Spanish aulon is prob- 
able, although the Indians accent the first syllable, 
giving it a sound difficult for us to imitate, some- 
where between wh and the German @. 
The accompanying illustrations represent the 
specimens taken from the Vallejo mound in the 
year 1872, with which, as before stated, were found 
human remains and numerous aboriginal relics. 
x; They form a part of the Voy collection presented 
(Me. 64.) HALIOTIS to the University of California by Mr. D. O. Mills, 
BALONE. of San Francisco. 
These ornaments and this money, if we may consider the circu- 
lar pieces as the latter, are all made from the same species of Ha- 
liotis (H. rufescens Swainson), the common red-backed abalone 
of the coast, which has a range of nearly the entire shore line of 
the State; and a large species which sometimes attains a length 
of eleven inches. 
In Figure 2 of Plate II. we have an approximately circular 
disk ; Figure 1 in the same plate may have been nearly the shape 
of 2, and have become partially disintegrated and scaled or 
flaked off, since it was buried, through oxidation and decay. 
The dark patches on these figures represent the red exterior of 
the shell from which they were made, and which still remains 
on the specimens. Figure 3 is well worked out, a nearly perfect 
circle with the edges neatly serrated or toothed, as if done with 
a sharp piece of obsidian, while Figure 4, though without appar- 
ent design, has been rubbed or rounded so as to make the edges _ 
smooth, as have also the pieces figured in 1 and 2, and the holes 
have been carefully perforated. Figure 4 shows the mark where 
a hole was started and not completed, probably from its being 
too near the edge. 
Over a dozen of these disk-shaped pieces, including those figured, 
were found by Mr. Voy, and Mr. Yates also records approximately 
similar forms of smaller size, though he does not state the species 
of Haliotis from which his specimens were made. Mr. Henry Ed- 
wards, the entomologist, has also obtained this abalone money 
from the kitchen-middens of Marin County, near Saucelito. 
Mr. Powers, referring to the use of Haliotis, says, “ The uhllo 
pieces : are of a uniform size on the same string; they do not mix 
them. The dollar pieces (Plate II., Figure 5) are generally 
- about one and one quarter inches thing and an inch wide; the 
smaller about as long but narrower; . . . a couple of fragments
