A tergum of a Lepadide, apparently of Scalpellum magnum Wood, Dar- 
win, unfortunately was lost, together with a very minute specimen of an 
Ostracod, Cythere sp. No species of an Ostracod has been “found hereto- 
fore in the Atlantic Miocene. Scalpellum magnum,t however, has been 
found at Petersburg, Va., but misinterpreted. The carina has been 
described by H. C. Lea as Patella acinaces,} and the scutum as Avicula 
multangula,§ and these species appear in the Miocene lists of Conrad || 
and Meek.{ Prof. A. Heilprin, in his list of Tertiary fossils from Virginia, 
also enumerates Patella acinaces,** while Avicula multangula is put 
among those species of H. OC. Lea which are ‘‘based upon young shells, 
or upon such as barely admit of characterization. ++ 
As my opinion about these fossils differs so essentially from that of a 
number of authors, I consider it necessary to give the figures of the type- 
specimens in the collection of the Academy of Natural Sciences in Phila- 
delphia (Fig. 11, 11a, 12, 12a), so that others may be able to form their 
own judgment. The original figures of H. ©. Lea are not sufficient for 
‘this purpose. 
* One of my specimens has three embryonic whorls preserved. They are smooth and 
this apparently shows that the species is not identical with the Eocene Cerithiopsis con- 
stricta H.C. Lea sp., although adult specimens without nucleus look alike. See Be- 
richte d. Senckenberg. Naturf. Gesellsch., Frankfurt a. M., 1887, p. 8, Pl. 2, fig. 28; and
