always been misinterpreted and is liable to continue to be misinterpreted, tbe 

 name is dropped finally and tbe term Creinaerinidse. proposed by Ulricb in 1886, 

 is used in its stead. A review of tbe evidence led to an investigation of tbis 

 group of crinoids as a wbole. witb tbe result tbat a reclassification was found 

 to be necessary. Of tbe seven or eigbt genera previously suggested or recog- 

 nized, all but tbree were discarded on tbe ground of preoccupation or actual 

 synonyms. Under tbe searching and comprehensive treatment, bowever. it be- 

 came necessary to institute six previously undescribed genera. Tbese studies, 

 wbicb included tbe type specimens of all tbe species available, were based in 

 large part upon tbe extraordinarily complete representatives of tbe family in 

 tbe Frank Springer collection.

RICHMOND FORMATIONS OF THE PROVINCES OF ONTARIO AXD QUEBEC IN 



CANADA 



BY A. F. FOEESTE 



(Abstract) 



Richmond formations are widely extended throughout Ontario and Quebec. 

 but belong chiefly to two horizons comparable witb the Waynesville and Saluda 

 of Cincinnatian areas. The Queenstown shales are of Ordovician age. South 

 of Georgian Bay they contain a Saluda fauna. Farther westward, on Mani- 

 toulin Island, the Queenstown shales are represented by much more fossilifer- 

 ous, blue and light brown limestones and clays. Paleozoic seas probably trav- 

 ersed the areas now mapped as Huronian and Arc-beam There are traces 

 of the Richmond fauna of Anticosti on Snake Island, in Lake St. John, and 

 at various localities between Ottawa and Three Rivers, but these traces are 

 not sufficient to suggest any free connection with the Anticosti area. The 

 Saluda may have been part of a circumpolar fauna. The Waynesville appears 

 to have entered Ontario and Quebec chiefly from the Cincinnatian areas of 

 Ohio and Indiana.

CRIXOID GEXUS SCTPHOCRIXUS AXD ITS BULBOUS ROOT CAMAROCRIXUS 



BY FBA3TK SPBZXGEB 



(Abstract) 



This paper is based chiefly upon a remarkable collection of specimens which 

 the author considers to be specifically identical with Scyphocrinus elegans of 

 Zenker from Bohemia. The material was obtained during the past season in 

 Helderbergian strata, near Cape Girardeau. Missouri, and consists of numerous 

 finely preserved crowns of great size — some 18 inches in length — intermingled 

 with a mass of long stems, and many of the chambered bulbs heretofore de- 

 scribed as Camarocrinus all formed part of a large colony.
