Office and Laboratory Work 
C. M. Sternberg made a careful study of the hooded hadrosaurs of the 
Belly River Cretaceous and prepared a paper setting forth his observations 
and describing three new species. Most of the work done by the vertebrate 
laboratory staff was confined to specimens that would aid in the above 
research. In this connexion a considerable part of the skeleton of a new 
species of Lambeosaurus and two other skulls were prepared. Four skulls 
were mounted for museum exhibits and four collections sent in for identifi- 
cation were reported on. 
L. S. Russell has completed studies on fossil turtles from Saskatchewan 
and Alberta, with publication of result. His office work has also included 
preparation and study of invertebrates and vertebrates from the Milk 
River formation of Alberta, preparation of a paper entitled “ Musculatum 
and Functions in the Ceratopsia,” preparation of casts of specimens for 
exchange with other palaeontologists, and sorting and packing of S. R. Kirk 
collection of Manitoba Cretaceous fossils at Winnipeg. 
The office work of A. E. Wilson has included: study of Ostracoda in 
connexion with the wells of the Borings Division; study of fossils in con- 
nexion with the Ottawa map sheet; continuation of "work on type catalogue; 
completion of labels for case in Exhibition Hall. 
F. H. McLearn has devoted some time to a study of Triassic fossils 
from Peace River district. 
W. A. Bell has been engaged chiefly in the preparation of a memoir 
on the fossil plants of the Sydney coal field which deals with their descrip- 
tion, illustration, and stratigraphic distribution. 
About the usual number of special reports on fossils for members of 
the staff have been prepared. Reports on fossils sent in by the Quebec 
Bureau of Mines and on collections from other sources have been furnished 
on request. 
Museum Exhibits 
Additions to the Museum exhibits include a case showing various types 
of lamination. A case has been prepared by A. La Rocque displaying many 
of the brilliantly coloured tropical molluscan shells, examples of the several 
classes of the mollusca, and the uses that man makes of the molluscs. A 
habitat group of Cretaceous dinosaurs, with restorations by L. S. Russell, 
of Gorgosaurus libratus and Chasmosaurus belli , natural size, has been 
prepared by C. E. Johnson. 
The services of L. S. Russell were loaned to the Manitoba Museum 
for the purpose of mounting there a skeleton of the plesiosaur Trinaerome- 
rum. A description of the specimen was also prepared. 
Educational Work 
A dinosaur habitat exhibit, on a scale of natural size, including two 
dinosaurs and associated plant life of Cretaceous times, was shown at the 
Ottawa Exhibition as part of the National Museum exhibit. 
Guides were supplied for a series of visits of Normal School students 
to the Museum. The natural science students in the Ottawa Collegiate 
Institute were also supplied with guides on two field trips to study geological
