THE RICHMOND FAUNAS OF LITTLE BAY DE 

 NOQUETTE, IN NORTHERN MICHIGAN. 



A. F. FOERSTE. 



The fauna of the Richmond exposures along the northern shore 

 of Drummond island evidently is merely a western continuation of 

 that found on Manitoulin island, and extending thence eastward along 

 the southern shore of Georgian Bay and north of the western half of 

 Lake Ontario, almost as far east as Toronto. It contains the same 

 abundance of coralline growths, such as Stromato cerium huronense 

 Billings, Tetradium huronense Billings, Columnaria alveolata Gold- 

 fuss, Calapoecia huronensis Billings, Streptelasma rusticum Billings, 

 and Protarea richmondensis Foerste. It contains also the associated 

 fauna known from the Richmond of the Canadian localities just 

 mentioned. 



Nothing is known at present of the Richmond fauna on St. 

 Joseph island nor of that part of the northern peninsula of Michigan 

 extending between Lakes Superior and Michigan, until we reach the 

 eastern shore of Little Bay de Noquette, about four miles east of 

 Escanaba, on the opposite side of the bay. Here only the faunal list 

 published by Rominger (Geol. Surv. Michigan, 1873, part III, page 

 52) is available, and it was for the purpose of supplying further data 

 that the following studies were undertaken. 



A lighthouse is located at the southern end of the peninsula be- 

 tween Little and Big Bay de Noquette. The Skaug Brothers store is 

 located two miles north of the lighthouse, and two miles farther north 

 is the present location, in a farm house, of the post office called 

 Stonington. A short distance southward, an east and west section road 

 leads down to the Farmer's Dock. Two miles farther north, at another 

 east and west section road, is the store of J. B. Stratton, and a mile 

 and a half farther north is another road corner, immediately south of 

 which the shallow ditch following the road exposes the basal part of 

 the cherty Richmond, the top of the underlying argillaceous Richmond 

 strata being exposed a short distance farther southward. Passing
