14G CRETACEOUS L AIMELLIBRANCHIA. 



(derived from tlic Upper Greensand) of Aller Vale near Torquay. They have 

 been identified with C. ligeriensis, d'Orbigny/ by Mr. Jukes-Browne, wlio has 

 compared them with examples of that species from the Cenomanian of Vimoutiers 

 and Orliiquet, and states that the agreement is very close. The English specimens 

 also resemble C. Noudiana, d'Orbigny," of which a cast only is figured b}^ 

 d'Orbigny, and was at first regarded as C. lifjcriemis^. An example from 

 Wilmington is in the Sedgwick Museum. Otiiers from Aller Vale are in the 

 'i\ir(|uay Museum and in the Sedgwick Museum.
