means by which it was possible to recognize them with cer- 

 tainty, and were duly catalogued, numbered and fully re- 

 corded in the department catalogue. Their value was thus 

 greatly enhanced. The routine of cataloguing, labeling, re- 

 labeling and rearranging collections for more convenient ref- 

 erence or saving of space has been carried forward as usual. 



The preparation of the Alberta dinosaur collections was 



continued with vigor, and considerable progress was made. 



The fine carnivorous dinosaur skeleton secured 



Preparation 



and from Mr. Sternberg in 1918 has been mounted 



Exhibition as a p ane i [ n an interesting and characteristic 

 pose, contrasting with the skeleton of a larger species finished 

 a year ago, which is also mounted as a panel, but placed sub- 

 stantially in its position as found in the rock. Two other 

 skeletons of large carnivorous dinosaurs from Alberta are in 

 course of preparation, one planned as an "open mount," the 

 other as a panel. A partial skeleton of Palaeo seine us, showing 

 the bony armor of the neck and forequarters in place behind 

 the skull, has been further prepared but not yet completed ; 

 this is a very difficult specimen but highly instructive as to the 

 body armor of the Armored Dinosaurs. 



A mounted skeleton of Moscliops, a large and very remark- 

 able reptile from the ancient Permian Karroo formation 



of South Africa, has been placed on exhibition, 

 Extinct temporarily installed in the Hall of the Age of 



Mammals, near the entrance. This is a very 

 strange and odd-looking reptile, with short tail and small hind- 

 quarters, and a very short, deep, massive head, suggesting that 

 of the muskox to which its scientific name alludes ; but the pro- 

 portions and pose of the body and legs carry more suggestion 

 of the walrus, squat, massive, clumsy-looking, and dispropor- 

 tionately small behind. It should command respect, however, 

 on account of its great antiquity, for it belongs to the Permian 

 period of the Palaeozoic, before the dawn of the Age of 

 Reptiles. 



A skeleton of Pieranodon, the giant Flying Reptile, has 

 been mounted and placed on the wall of the corridor diag-
