formation along Red Deer river above Drumheller, Alberta. These include 
a nearly complete skull of Hypacrosaurus , a disarticulated skull of Sauro- 
lophus, two fairly complete skeletons of Ornithoviimus , and a complete 
forelimb of a small Albertosaurus; fish, plant remains, and invertebrate 
fossils were also collected. A new genus and three species of fish not 
hitherto reported from the Edmonton beds were obtained. 
The collection of fossils made by Mr. Soper in Baffin island is note- 
worthy because of the presence in it of a Utica fauna identical with that 
found in Ontario and New York state. 
The division is indebted to various friends for gifts. Among these 
may be mentioned a Pleistocene crustacean from Ottawa, not previously 
found as a fossil in North America, which was presented by Brother 
Alphonse of the La Salle Street Academy. 
Benjamin L. Bowling of the Iowa State Highway Commission has sent 
to the Survey a good collection of Middle Devonian stromatoporoids 
from Iowa. 
Dr. Alexander Wetmore of the Smithsonian Institution has contributed 
to our collections a cast of types of the fossil bird Diatryma gigantea. 
The American Museum of Natural History has presented to our collec- 
tions a cast of the skull of the small dinosaur Thescelosaurus. 
Office and Research Work 
Several special reports on fossils have been prepared for other members 
of the staff by members of the division. Preparation of these has involved 
the study of considerable collections from Baffin island, N.W.T., and 
various parts of eastern and central Canada. Various reports on fossils 
from drill cores have been supplied to oil companies and to private indi- 
viduals. 
F. H. McLearn has continued the study of the Jurassic faunas of 
Skidegate inlet, Queen Charlotte islands, B.C. The work on Jurassic 
Ammonoidea which is now more than half completed is part of a compre- 
hensive study of the Mesozoic stratigraphy and paleontology of Skidegate 
inlet. 
W. A. Bell has described the Mesozoic flora collected during the summer 
of 1926 from Moose River basin, northern Ontario, by F. H. McLearn. 
Mr. Bell has also described a collection of Cretaceous plants made by F. A. 
Kerr in Cassiar district, B.C. 
E. M. Kindle has completed a paper on the Devonian fauna of lower 
Peace river and begun a study of the Conodont fauna from the lower 
Mackenzie River valley, collected by him. A short paper on the discovery 
of the Leptodus in Canada has been published. The results of the study 
of water stratification in certain small lakes and its influence on sedimenta- 
tion have been prepared for publication. 
Miss A. E. Wilson has been on leave for university work during a part 
of the year. 
Most of the graptolites collected have been studied by Dr. Rudolf 
Ruedemann of Albany. Dr. C. D. Walcott and Dr. Chas. Resser have, 
as in previous years, furnished reports on the Cambrian fossils collected 
by the Survey in British Columbia.
