522 Canadian Record of Science 



Although only one ornithologist was employed, a 

 goodly number of birds was reported, Mr. Taverner 

 having volunteer workers corresponding and co-oper- 

 ating with him, and sending him specimens, Perhaps 

 the most valuable of the list of birds is that collected by 

 Capt. Joseph Bernard, on the Arctic Coast, N.W.T. 

 They number 33 in all. 



CANADA DEPARTMENT OF MINES, GEOLOGI- 

 CAL SURVEY, MUSEUM BULLETIN No. 12, 

 ON EOCERATOPS CANADENSIS, WITH 

 REMARKS ON OTHER GENERAL GENERA 

 OF CRETACEOUS HORNED DINOSAURS. 



By Lawrence M. Lambe. 



This Bulletin embraces, in detail, the report of the 

 veteran Vertebrate Paheontobogist, Mr. Lambe, of which 

 an outline is given in the volume of the Geological Sur- 

 vey Report noticed above. 



The following is a brief description of the ancient 

 inhabitant of the Red Deer region of Alberta: 6 'Eocera- 

 tops appears to have had a short skull, compact and deep 

 in front, and tapering behind. The lower jaw is robust, 

 the nasal bones are remarkably deep and the supra- 

 orbital horncores are large in comparison with the in- 

 conspicuous nasal horncore. This compactness of the 

 anterior half of the skull with great depth is also found 

 in Brachyceratops, a form in which the nasal horn was 

 the principal weapon of defence. In comparison with 

 Eoceratops, the later Triceratops has lengthened the face 

 and added greatly to the size of the supraorbital horn- 

 core to the neglect of the nasal horn. In Diccratops, 

 with the enlargement of the browhorns, there is the 

 concomitant non-development of the nasal one." The 

 Bulletin is illustrated with eleven plates, which enable 

 the reader the more clearly to grasp the contents of the 

 valuable report.
