 tographica, xxxiv, p. 178, pi. 20, f. 10.

D. INFORTUNATUM Pils. & Sb., 1898. This name will replace D. 

 gardneri S. & P. = D. acuminatum Gard., (p. 222), not of Holzap- 

 fel. 



" Miiller described from the Cretaceous of Aix-la-Chapelle, Z>. 

 eidaris, D. ellipticum and D. rugosum. The last species is certainly 

 not a Dentalium, but the internal cast of a Gastrochcena (?), of which 

 the shell has not yet been observed, though the fossil is very abund- 

 ant. What Miiller understood to be D. ellipticum I cannot say, 

 nor what he identified as D. eidaris. In Muller's collection there 

 is a piece of chert containing the impression of the anterior end of 

 a Cidaris spine with the label Dentalium eidaris Gein." (Holzapfel, 

 Palseontographica, xxxiv, p. 17-0).

Gadila aqucnsis HOLZ., Palseontographica, xxxiv, p. 179, pi. 20,
