188 REVIEWS—NORTH WEST TERRITORY. 
Grindstone Point, Lake Winnipeg, composed of Chazy Limestone, 
illustrating the exceedingly picturesque character that generally pre- 
vails throughout that Lake Coast. Extracts from the reports and 
narratives of Messrs. Foster and Whitney, Sir John Richardson, Dr. 
Owen and other observers, accompany Professor Hind’s own notes, and 
supply many new hints whereby to judge of the mineral resources and 
the prevailing geological character of this great unoccupied territory. 
To complete the report in its scientific bearings on the geological 
aspects of the various districts explored, the services of the American 
Paleeontologist, Mr. F. B. Meek, and of Mr. E. Billings of the Cana- 
dian Geological Survey, have been called into requisition ; the former 
describing Cretaceous fossils, and the latter those of the Silurian and 
Devonian formations. It was impossible, in so rapid an exploratory 
journey, with many other objects demanding the special attention of 
the observers, that anything like a complete paleeontological series of 
illustrative specimens could have been secured; but enough has been 
done in this department to supply interesting materials for comparison 
with the Nebraska territory, and the rocks of the great basin of the 
Upper Missouri. Mr. Meek, whose labours in the latter district, are 
well known to American Geologists, remarks, after a general reference 
to the collections made by Professor Hind, in proof of the value of this 
portion of the exploratory party’s work: “‘It is very desirable that a 
good series of specimens should be obtained from this remote northern 
locality, not only for the purpose of determining the age of the forma- 
tion, but for the light they might throw upon far more interesting 
questions respecting the probable climatic conditions in these high 
northern latitudes during the Secondary Period.’ The fossil plants, 
Acephala, Gasteropoda, and Cephalopoda of the Cretaceous formations 
are minutely described, and the new species named. From the latter, 
we select one or two, which we are able to illustrate by means of the 
well executed wood engravings prepared for the report. Figs. 1, and. 
2, are Lamellibranchiata procured from their matrix of soft lead gray 
argillaceous rock, on the Little Souris River, and named after one of 
members of the exploring party, Anomia Flemingi. 
Plate II. is chiefly occupied by large and well executed figures of 
the Ammonites Barnstoni, the Ammonites Billingst; and a beautiful 
variety of the Nautilus, termed the Dekayi; but probably greater 
interest will be felt by many in the following less showy Productus, 
supposed to be from carbonifeous limestone, and therefore viewed.
