AFTERNOON SESSION.
At the afternoon session paper was read by
Dr. L. P. YANDELL of Louisville. Ky. on the Dis.
tribution Of Crinoidea in the Western States
The following abstract gives the results of DR..
Yandels observations:
DISTRIBUTION OF cRINOIDEA IN THE UNITED
STATES.
For several cars past, said DR.. andell, have
been engaged, conformity with Dr. y. +. Shumard,
in collecting the Crinoids of the Western States
With reference 20 = continuation of the work IN
dertaken on that subject 10y the late lamented DR..
Troost We have already collected about thirty
genera and more than two hundred species, show
ing that our country is richer than Gny other pat
Of the world in the remsins Of these curious tea
ants OF the deep.
They are found in the Oldest rocks which retain
any vestiges of organic beings. DR.. Shumard has
discovered them in the ssndstones Of Wisconsin
and Minnesota, which correspond - the Potsdsm
sandstone Of New-YOr At first they are few In
number, and occur in fragments; but they ia the
later formations, become abundant 10 the eqaiva
Tents of the Niagara group and s,taia their full
development In the Carboniferous system. They
were OF limited range, a species often being found
in only q angle locality, and rarely extending
over an area OF many miles. Not one is clearly
common 20 this country and Europe, though one
or two are claimed by both continents. Not one
the Lower Silurian differ not only In species bat
for the most part in genera also. from those which
occur IN the Upper ShGriaD System, and these
again from those found in the DWonlan, while
the genera aid species OF the CNb)nlier0us
era were different from those of the earlier ages.
The types OF the prOt0z0ic rocks are ScbtS0cTI
nus, G1zpt0cr7nus He,erocrinus, and Ageiqcrt.
nus those Of the Niagara ass are Cdry0crlHus,
Balan0c,lnus and EAcal yDtocrlnusi IL the Deyo-
Man system dctm0cyiHHs is first seen, and Putty
cr1nus, with many new forms, appears In the Car
boniferous system.
Prof AGAssIz made q communication in refer
erence to the Special Homologies ofthe true Star
Fishes and Crinoids, in which he traced the anal
ogy existing between these divisions Of the Ami
nal Kingdom but the subject is purely technical,
ard not of public interest.
The local Secretary, Mr. RAINEY, read paper
on a new theory OF Statement by Proportions,
which he claims 70 have discovered.
Major RICHARD Owen read a paper prepared
BY his brother. DR.. David Dale Owen, and Mr..
Schumard of Indiana, on the number and distri-
button of fossil specimens in the PaeozOic Rocks
Of Iowa, Wisconsin and Mlnnesota
Some miscellaneous business ensued, and ihe
Transactions came to close.
