Page 122 



Two views of the type of "Rhodocrinus" asperatus Billings. 



Most of the sutures and a few of the small plates of the tegmen were 



outlined on the photograph before reproduction. 

 The unique original is from the Chazy limestone and was found "in a quarry 



about 2 miles north of the city of Montreal." It is now in the Museum of 



the Geological Survey of Canada, at Ottawa.
