366 Mr. E. A. Smith on the Genera 



The following species have been placed In Eglisia, but 

 they do not in reality belong to that genus: — 



1. Eglum siibdecussata (Cantraine), Fi-^cher, Actes Soc.Linn. 



Bordeaux, vol. xxvii, p. 115 (1869). 



This species is now referred to Mesalia. 



2. Eglisia inacandrece, H. Adams, Proc. Zool. Soc. 1865, 



p. 753. 



Regarded as a variety of Mathilda quadricarinata (Brocchi), 

 and placed in the Pjramidellidse. Sacco has created a 

 family Mathildidse for this genus. 



3. Turrilella {Eqh'sia) si/mmefrica, Ilutton, Cat. Marine 



Moll. New Zeal. j). 30 (1873). 



Eglisia i^ymmetrica, id. Journ. de Coucli. 1878, vol. xxvi, p. 29. 

 This is a true T'urrittUa.

As in the case of Eglisia^ the introduction of this genus 

 must date from 1847, when a species was first associated 

 with it. 



Gray (Proc. Zool. Soc. 1847, p. 155) quoted, as examples 

 of his genus, Cerithium mesal, Adanso]\=: Turritella mesal, 

 Deshayes, a Turritella sp., and T. svlcata, Lamk. He 

 evidently considered the shell described by Adanson as the 

 type of his genus, since he founded the name upon that 

 species. Jeffreys*, therefore, was quite wrong in stating 

 that " the type of Gray's genus is Turritella sulcata of 

 Lamarck, a Grignon or Eocene fossil." 



Mesalia may be separated from Turritellahy certain features
