 Vertebrate Palaeontologist to the Geological Survey. 



The Geological Survey of Canada has continued for 

 many years now its explorations in the rocks along the 

 Red Deer River and in the Valley of the Belly River, 

 Alberta, with most encouraging results. Rich rewards 

 have been reaped in the shape of rare fossils, and these 

 have afforded scope for the application of the skill of Mr. 

 Lambe, the expert Vertebrate Palaeontologist of the De- 

 partment. He has greatly added to his already well- 

 established reputation by these last contributions to fossil 

 lore. The remains of new monsters of the Saurian type 

 are brought to light in the above series of interesting 

 papers, which have appeared in The Ottawa Naturalist, 

 Vol XXVII, May and December, 1813, January and 

 February, 1914, from which brief extracts are here 

 offered. 



The first of the papers has particular reference to the 

 osteology of the front feet, or hands, of a specimen of 

 Trachodon discovered last summer in the Edmonton for- 

 mation (Upper Cretaceous) or Red Deer River, Alberta, 

 by the Geological Survey- Vertebrate Palaeontological 

 field party, under Charles H. Sternberg. This specimen 

 is now being mounted in high relief preparatory to being 

 placed on exhibition in the Museum of the Geological 

 Survey, Ottawa. The skeleton of this Trachodon is al- 

 most complete from the front magin of the snout to the 

 sixth caudal vertebra, but the remainder of the tail is 

 missing. This defect, however, can be remedied to a 

 great extent in mounting the specimen, as fortunately a
