Euryta aciculata, H. & A. Ad. loc. cit. 
Two dead specimens alone of this shell were found by Mr. 
Darbishire with Euryta fulgurata; distinguished by long nodu- 
lous plaits at the upper portion of the whirl, in the last whirl 
slightly divided into two. Colour yellowish white with a brown 
spiral band on the nodulous portion, and a reddish band on the 
base. It does not agree with specimens received under the 
same name from the Bristol Museum, probably from the West 
Indies.* These are nearly related to A. Cosentini, Phil. from 
Naples. Menke considers them identical, Zeit. f. Mal. 1847,

p. 149. ?Is the Lamarckian shell the W. Indian species, and that from Aca- 
pulco distinct. Care must be taken not to confound it with Lamarck’s Terebra 
aciculina (An. s. Vert. vol. x. p. 250, no, 22) which is Buc. cinereum of Born, 
(v. Desh. in loc.) and ‘Terebra cinerea of Thes. Conch. p. 180, no, 87 :—P. Z, &.
