TYPE LOCALITIES 



Warren and Clinton Counties have furnished the type specimens 

 of a number of Richmond species, some of them so rare and so re- 

 stricted in vertical range that it was thought appropriate to record 

 the following observations for the benefit of future collectors. 



AgelacT'mus austini (Foerste) : The type of this species was col- 

 lected from the surface of the thick cap rock of the Drepanella 

 richardsoni bed of the Whitewater in Dutch Creek, near Oakland, 

 Ohio. It is also present at the same horizon in Hales Branch, also 

 near Oakland and in upper Cowans Creek near Villars Chapel, Clin- 

 ton County, Ohio. It has never been noted at any other horizon. 



Brachiospongia tubercuJata (James) : The type specimen was 

 found by a farmer and presented to the late Dr. L. B. Welch, of 

 Wilmington, Ohio. It was taken from strata exposed in a small 

 stream which flows into Todds Fork just below the bridge on the 

 Wilmington and Lebanon pike one mile west of Sligo, Clinton
