between the radial*, and that the radianal does not change its position, 
bur. when present, rests within the angle of two basals, thus showing 
that the one is radial, the other inter-radial in position. This plate, 
which in Iocrinus lies upon the radials, and which, in Poterioerinus, is 
said to have passed down to the basals, is a plate of the tube. 
Antigy/iMes from under Tuolumne Table mountain in California. By 
George F. Becker. Bulletin, G. S. A., vol. ii. pp. 189-200, with a 
plate, and one figure in the text: Feb. 20, 1891. If further evidence 
was needed, beyond that set forth by Whitney in "The Auriferous 
Gravels of the Sierra Nevada of California," to prove the occurrence of 
human remains and stone implements in the deep placer gravels of that 
state, underlying basaltic lava, the demonstration is amply supplied in 
this paper. A mortar and pestle found by Mr. J. H. Neale, and a 
broken pestle found by the well known geologist, Mr. Clarence King, in 
the gravel under the basalt of Table mountain, Tuolumne county, are 
here figured : and their perfect regularity of outlines and their polished 
(neolithic) character seem very surprising, as showing the skill at- 
tained by man before the great extension of the Sierra Nevada glaciers, 
which followed the outpouring of the lavas. After the date of these 
implements, the gravels were covered by the lava flows, displacing the 
streams, which have since cut canons 2,000 feet deep below the top of 
Table mountain. Mr. Becker believes that the Californian glaciation, 
subsequent to the basaltic lavas, was more recent than the glaciation of 
the northeastern states, and that certain Pliocene animals, w T hose re- 
mains occur in the same gravels, had survived to a late portion of the 
Pleistocene or Glacial period. In the same manner, the Equus fauna, 
formerly supposed to be Pliocene, is shown by Gilbert to have continued 
so late as to be contemporaneous with the second rise of lakes Bonne- 
ville and Lahontan, which was probably coincident with the latest 
Sierra glaciation. 
Notes on the early Cretaceous of California ami Oregon. By George 
F. Becker. Bulletin. G. S. A., vol ii, pp. 201-208; Feb. 20, 1891. 
That part of the Shasta group which is extensively represented in the 
Coast ranges of California, containing Aucella and a few other shells, 
has been supposed to be older than its part which has been studied near 
Horsetown, in Shasta county, containing Ammonites and numerous 
other fossils, but not Aucella. Beds recently discovered to be fossilifer- 
ous at Riddles, Douglas county, Oregon, combine these faunas ; and 
they are also found together by Dr. G. M. Dawson in the Queen Char- 
lotte islands. The Shasta beds in the Coast ranges and at Horsetown 
are therefore probably of the same age, which appears to be the Gault. 
With them are also to be included the Aucella-bearing strata of the 
gold belt in the Sierra Nevada. The original plication and upheaval of 
the rocks forming that range, once thought to have occurred at the end 
of Jurassic time, are thus referred to the close of the Gault epoch in 
the Cretaceous period.
