in the presence of internasal scuta, and should be referred to the 
genus Gyalopium Cope, of which it is the second species. It was 
described some years ago! as Ficimia publia Cope. The Pseudo- 
ficimia pulchra is the Geagras frontalis Cope} the difference from 
the other species of Geagras figured on the same plate, č. e., the 
separation of the nasal from the preocular by an interspace not 
eing of generic value. Scolecophis Fitz., should be Scolecophis 
Cope, who first described the genus. Homalocranium D. & B., 
is Tantilla B. & G., of prior date. Here should come the genus 
Enulius Cope, which is truly glyphodont, though the authors of 
this work assert the contrary. Ogmius should also be placed 
near to Stenorhina in the glyphodont series.—E. D. C. 
CHAMBERLAIN’s GEOLOGY oF WIsconsIN®,—This is not only one 
of our best State reports, but one of the most valuable and interest- 
ing. Beginning to look casually over the first part of Vol. 1, en- 
titled General Geology, by the chief geologist, we expected to 
find the usual résumé for popular use, but while it is entertaining, 
for it held our attention from its able summary of the whole 
Story, it will continue to have permanent value from its discus- 
Sion of the Archzan age as well as the Glacial epoch. We 
should unhesitatingly recommend any beginner or advanced stu- 
dent in geology to read this part of Vol. 1 in connection with his 
geological manuals 
The candid, well-balanced mind of the chief geologist is seen 
throughout the entire narrative as well as in the discussions and 
references to the opinions and works of others. It is evident 
t the survey has been in good directive hands, while the re- 
Ports of the assistants prove that the details have been carefully 
and skillfully elaborated. The people of Wisconsin are to be con- - 
gtatulated on the results of such excellent work, and on having 
them Presented in a simple, intelligible form. 
ginning with the hypothetical and pre-Laurentian history of 
Wisconsin and of North America in general, which is discussed 
in a fresh and comprehensive way, we find a good sketch of the 
«an age, which seems to us, in some points, more satisfactory 
7 that given in the text-books. To be sure nearly every point 
C interest connected with this age is under debate. Professor 
tion soey however, adopts Selwyn’s view that the upper por- 
mestone and iron, as well as graphite, belong in reality to a 
or Huronian age. “ All the facts thus far disclosed in Wis- 
Pport this view, which, pending the results of investiga- 
must yet occupy some years, we shall assume to be
