Note Bv EprroR.—Photographs of this skull sent by Mr. Under- 
wood show that it belongs to the bison, Bos americanus. This is, I 
believe, the most northern locality at which it has been found east of 
the Mississippi valley.—E. D. Core. 
Geological News.—Palzeozoic.—In a review of Dr. Ells’s Re- 
port on the Geology of a Portion of the Province of Quebec, C. D. 
Walcott agrees with the author in condemning the name Quebec 
oup. In view of many new facts brought to light by the study of 
the past fifteen years it has become misleading and unintelligible. In 
its stead Dr. Ells's proposes to use the name Levis for the local develop- 
ment of the Calciferous terrane about Quebec, and the name Sillery 
for the passage beds and Cambrian strata of the St. Lawrence valley in 
the vicinity of Quebec. This suggestion has the hearty endorsement 
of Mr. Walcott. 
C. R. Van Hise (Bull. Geol. Soc. Am., Vol. L, pp. 203-244) con- 
firms Newton's views as to the eruptive origin of the granite core of 
the Blacks Hills, and its pre-Cambrian age. He further states that the 
zone of schists about it was developed and deeply eroded before the 
beginning of Pal&ozoic time. 
Sir Wm. Dawson and Dr. G. J. Hinde have recently described some 
new species of fossil sponges from the Siluro-Cambrian at Little Metis, 
on the lower St. Lawrence. These specimens are especially interest- 
ing since they throw fresh light on the character of the earliest-known 
orms of these organisms, and their discovery is the more opportune 
from the fact that our knowledge of the existing hexactinellid sponges 
—the group to which nearly all these fossils belong—has been vastly 
increased by the work of Prof. F. E. Schulze, of Berlin, on the 
hexactinellid sponges dredged up by the Challenger Expedition, and 
thus we are now better enabled than hitherto to compare the fossil and 
recent forms. Twelve species, representing six genera, are descri 
and figured. 
The second part of the Contributions to the Micro-Paleontology of 
the Cambro-Silurian Rocks of Canada has been prepared by E. O. 
Ulrich. It consists of a descriptive report on some fossil Polyzoa and 
Ostracoda from Manitoba, and is illustrated by two full-page litho-
