Maryland, and Pamunkey river, Virginia, listed the species and 

 described in the Academy's Proceedings as new : Cytherea nuttal- 

 liopsis, Pseudoliva scalina, LcEvibuccimini lineahcni, Fusus subte?i- 

 uis, F. interstriatus , F.engonatus, Strepsidura subscalarinus, Pleu- 

 rotoma inoniliata, Pyrula multarigulata, Solarium cupola, S. del- 

 phinuloides , Dentaliimi inicro-stria. 



The next year Prof. Heilprin furnished the Proceedings with 

 some ' ' Notes on the Tertiary Geology of the Southern United 

 States." From Smith's notes he gives a secftion at Woods 

 bluff, near the mouth of Bashi creek, and also a crude dia- 

 gram representing the Woods bluff beds as passing beneath, 

 i. e. stratigraphically below the " Buhrstone." He coins the 

 term Eo-lignitic for these sub-buhrstone deposits and thus sub- 

 divides the whole Alabama Eocene : 



4. " White limestone" ( Jacksonian) 50? feet 



3. Claibornian 17 feet 



2. "Buhrstone" (Siliceous Claiborne of Hilgard ) 



about ■ 250? feet 



I. Eo-lignitic 50? feet 



Pradlically the same conclusions are reiterated in ' ' Contribu- 

 tions to the Tertiary Geology and Paleontology of the United 

 States" published in 1884, though attention is called to Johnson's 

 note in Science, vol. ii, 1883, indicating a considerably greater 

 extension of the Eocene to the northward than geologists were 

 generally aware of. 



It is, however, to Prof. Smith that our present knowledge 

 of the lyignitic stratigraphy of the State is mainly due. His 

 labors in this field he briefly summrizes as follows : 



"During the summer of 1883 a trip was made by the authors, 

 in a small steamer, down the Tuscaloosa (also called Black War- 

 rior or Warrior) river, from Tuscaloosa to its confluence with the 

 Tombigbee, down the latter stream to its confluence with the 

 Alabama, down the Alabama and Mobile r ivers to the head 

 of Mobile bay, and thence up the last two rivers to Prairie 

 bluff. 



"The trip by steamer was made at the joint expense of the U.S. 

 Geological Survey and the Geological Survey of Alabama. 



"The first draft of this bulletin was prepared with the data col- 

 ledled during this trip, there being added thereto information
