PROCEEDINGS OF 
[Dec, 
Mr. Markoe stated, that during a portion of the months of October 
and November, he accompanied Mr. T. A. Conrad, Palaeontologist of 
the New-York Survey, on a geological excursion, for the purpose of 
examining the medial tertiary (of Conrad, being the equivalent of 
Lyell’s older pleiocene) formations of the counties of Calvert and St. 
Mary's, Maryland, during which they had collected a large number of 
fine fossils, embracing many new species. Among others Mr. Markoe 
obtained from the Calvert cliffs a large fossil head, ( Deljphinus ,) to 
which he proposed to give the name D. Calvertensis. 
Mr. Markoe further stated, that Mr. Conrad was preparing a re¬ 
port upon the subject, to the National Institution, which would be 
published in the forthcoming Bulletin of its proceedings, accompa¬ 
nied by plates figuring some of the new fossils, and the head, of which 
a description would be given.
