figure of Dalmanella emacerata^ namely figure I on plate 2 of ! 
the Fifteenth Report, New York State Cabinet of Natural His- 
tory, appear to be those which were obtained from the Fulton 
or Triarthrus becki horizon, at Cincinnati, Ohio. Considering | 
the fact that the so-called River quarries were largely operated | 
at the time when the earlier collections were made at Cincinnati, | 
this identification is not improbable. In favor of this identifica- | 
tion is the coarseness of the radiating striae evidently distinctly !| 
greater than that of the specimen represented by figure 2 on the j|i 
same plate. A specimen from the Fulton bed is figuied in the |l 
present number of this Bulletin. lij 
As a matter of fact, the type specimen of Dalmanella emacerata, ||j 
preserved in the American Museum of Natural History, appears ji i 
to be not quite as coarsely striated as these Fulton specimens, or j’ 
as the first published figure. i|!

This form would not be considered distinct from Dalmanella L' 
emacerata-filosa, were it not for the fact that intermediate forms li i 
are unknown at present. The shorter length, resulting in a semi- || i 
circular, rather than subquadrate outline, is the chief distinguish- ! 1 
ing feature. See figure 2 on plate 2 of the Fifteenth Report^ New '
