On Eoceratops canadensis , gen. nov., with Remarks on Other Genera 
of Cretaceous Horned Dinosaurs. 
By Lawrence M. Lambe. 
The above species was established in 1902 1 on parts of the 
skull of one individual collected by the writer in the Belly 
River formation on the east side of Red Deer river, Alberta, a 
short distance below the mouth of Berry creek, during the sum- 
mer of 1901. In the original description the species was referred 
to the genus Monocionius, Cope. 
The type material consists of the right squamosal (Cat. 
No. 1254a), the right posterior lateral extension of the parietal 
(Cat. No. 1254b), the right postfrontal and prefrontal with the 
supraorbital hom-core rising from the former bone (Cat. No. 
1254d), the right nasal including the right half of the nasal 
hom-core (Cat. No. 1254c), the left dentary without teeth 
(Cat. No. 1254e), and an anterior dorsal vertebra (Cat. No. 
1254). 
More detailed descriptions, with figures, of the squamosal 
and the posterior parietal bar were published in 1904 2 .
