Visiting scientists have in two instances restudied and prepared for 
our publications new descriptions of museum types. Dr. F. A. Bather of 
the British Museum has redescribed Dendrocystis? paradoxica Billings. 
Dr. Alexander Wetmore, Assistant Secretary of the Smithsonian Institu- 
tion, has figured the previously unfigured type of the fossil bird Cyphornis 
magnus from British Columbia. 
Dr. Auguste F. Foerste has described three new cephalopods from 
Survey collections of Nova Scotia Devonian fossils. 
The fossil flora of the St. Eugene silts of British Columbia was sub- 
mitted to Dr. Arthur Hollick of the N. Y. Botanical Garden. The study 
of this flora has been completed and the results were published in the 
Memoirs of the N. Y. Botanical Garden, vol. 7, 1927. 
Museum Exhibits 
One of the new exhibits in the hall of palaeontology is a collection of 
fossil and recent ripple-marks. The significance of the different types of 
ripple-marks in interpreting the history of sedimentary rocks is illustrated 
by plaster of Paris duplicates of freshly made ripple-marks and of thread- 
like lines of sand left on the strand line by spent waves. In another recently 
installed exhibit different types of limestone are shown and the factors 
concerned in their production are indicated. 
Considerable progress has been made towards completing the pre- 
paration of the unique skull of Styracosaurus. 
The skeleton of a very fine specimen of Pliocene horse has been 
mounted for exhibition during the year, but lack of space prevents its 
exhibition. Exhibition of additional material from the rich collections 
now on hand will have to await the acquisition of more exhibition space.
