J. S. Newberry, in the Proceedings of the U. S. National Mu- 
seum, Vol. v, pp. 502-514, published “ Brief descriptions of fossil 
plants, chiefly tertiary, from Western North America.” No illus- 
trations accompany these descriptions of fossil plants, mostly col- 
lected by Dr. F. V. Hayden, though many were collected by 
Professor T. Condon, by Professor J. J. Stevenson and I. C. Rus- 
sell. Fuller descriptions with illustrations will appear in a vol- 
ume which is to form one of the reports of the U. S. Geological 
Survey. ; 
New York.—The second part of Vol. v of the Palæontology 
of New York, by James Hall, has appeared. It contains descrip- 
tions and illustrations of the Gastropoda, Pteropoda and Cepha- 
lopoda of the Upper Helderberg, Hamilton, Portage, and Chemung 
groups, illustrated by a volume of 113 very good plates. Profes- 
sor Hall has also published a few copies of the plates of part first, 
of Vol. v, of the Palzontology of New York: “ Lamellibranchiata, 
plates and explanations.” There are twenty pages of explanations, 
and eighty plates of very good drawings, especially those drawn 
by J. H. Emerton, of Lamellibranchiate shells from the Upper 
Helderberg, Hamilton, Chemung, and Waverly groups, Professor 
Hall Still retaining the latter group in the Devonian. “The 
author has been allowed to purchase, from the Secretary of State, 
100 copies of the plates already lithographed, for this volume, 
which are published in this form in order to make them available 
for the use of Scientific institutions and students in palzontology. 
The text and additional plates of the volume, whenever published, 
will be sent to the parties receiving this portion of the work.” 
S. H, Scudder, in the Proceedings of the American Academy 
y Arts and Sciences, presented on October 10th, a paper on the 
ossil white ants of Colorado from Florisant ;” six new species 
and one new genus are described ; and Mr. Scudder argues that 
‘heir presence at Florisant is indicative of a much warmer cli- 
mate than the locality now enjoys.
