very desirable that any one possessed of facts connected with so 

 interesting a locality should publish them as soon as possible. 



Fossil Infusoria of 



I have re- 



W 



or 



3 



specimens of fossil infusoria from several new localities discover- 

 ed by himself in Virginia, viz. at Rappahannock Cliffs, Stratford 

 Cliffs, Brown's Mills, Westmoreland Court House, and Meherrin 

 River. I am also indebted to Mr. Tuomey for a large collection 

 of infusorial specimens from the localities discovered by himself 

 in the neighborhood of Petersburg ; and specimens from Hollis 

 Cliffs, Va. have been given to me by Mr. Tuomey, by Prof. Ro- 

 gers, and by Francis Markoe, Esq., but I have not been informed 

 who was the discoverer of this locality. 



In order to show in a connected manner the results of the ex- 

 aminations hitherto made upon the infusorial remains in the ter- 

 tiary of Virginia and Maryland, I present the following table, 

 which also includes a list of the species found by Ehrenberg in 

 the Tripoli of Bermuda. The first four columns are on the au- 

 thority of Ehrenberg ; the others are the results of my own ob- 

 servations, and are very far from being complete, as many of 



are still unknown to me. I have carefully 

 refrained from including in the lists anv form of whose true name 

 I felt any doubt. As specimens from all these localities have 

 been sent by me to Ehrenberg, we may shortly be able on his 

 authority to give much more complete lists. 



In this table a (*) placed opposite to a species, shows that it 

 occurs at the locality whose name is placed above the star. If a 



species 



(t) 



it indicates that the 



species is, according to Ehrenberg, known in the recent as well 



as in the fossil state. Where 



omitted by Ehrenberg in his lists for the first four localities, I 

 have added a B to the star. 



Where the name of the discoverer of a locality is known to 



me, I have added it to the name of the place.
