has a very narrow elevated crest. This induced Lambe to call it the 

 crowned saurian. The teeth have minute denticles along the margins 

 in the front part of the jaws, which are not so pronounced in the back 

 part. Quite a number of the bones of the skeleton were found with 

 this specimen. 



I was so fortunate as to find a fine skull of Monoclonius nasicomis 

 Brown. My son Levi has beautifully restored it. It lay on the side of a 

 steep slope, part of one side washed down the hill. However, when 

 they were restored, very little was missing. It is the best specimen my 

 parties found in the four years we collected there. It is 4V2 feet long, 

 and as far as I know, equalled only by the type in the American Museum, 

 New York, where they have the entire skeleton. I have described these 

 dinosaurs in my i-ecent book, "Hunting Dinosaurs in the Red Deer River, 

 Alberta, Canada," and need not go into details here. 



In addition to the dinosaurs collected, I secured a large collection of 

 scattered bones that will be of value as hand specimens to illustrate the 

 wonderful fauna of the Pierre age. 



We secured some fine turtles. Two, in fact, have nearly perfect shells. 

 One, Lambe's Boremys pluchra, a new species, Levi found in 1913. The 

 other is evidently new, and is the only one I have found in the Belly 

 River Series, either in Montana or Canada, where the ribs are not 

 coossified to time margin. It resembles somewhat the sea tortoises of 

 the Niobrara chalk of Kansas. Then we have a beautifully sculptured 

 plastron of a new species of Aspiderites, a form that was not covered 

 with horny scutes, half the plastron of a large Adocus that must have 

 been three feet long in life. This shows the marks of very strong horn 

 plates. 



Glacial Moraines in the Vicinity of Estes Park, Colorado. 



Lymax C. Wooster, State Normal School, Emporia. 



While spending his August vacation near Estes Park village, the 

 writer unexpectedly penetrated a region of enormous glacial activity of 

 prehistoric times. Having given years to the study of the moraines of 

 Kansas, Wisconsin, Michigan, Illinois, Indiana and Ohio, belonging to 

 the great continental glacier that once covered the northern United 

 States from Dakota to Cape Cod, the writer became at once interested 

 in these moraines of the alpine glaciers of the Rocky Mountains that 

 formerly filled the upper valleys of the Thompson river and its tribu- 

 taries. 



The introduction to the moraines came when a party of relatives and 

 friends laid a picnic luncheon in the Thompson river at the gateway to 

 Moraine Park. Giant bowlders filled the river, so we were safe from 

 a wetting. The river here falls in cascades one hundred feet through 

 and ever the terminal moraine of a glacier that formerly filled Moraine 

 Park. This glacier undoubtedly received tributary ice rivers down 

 Forest, Spruce and Fern canyons and was in its time a glacier of no 

 mean dimensions. It pushed but two or three miles beyond the mouths 

 of the canyons, for it encountered a great glacier from the southwest
