456. EUEYTA ACICULATA, Lam. 



PBuccinum aciculatum, Lam. An. s. Vert. vol. x. p. 175, no. 41. 

 Terebra aciculata, Gray in Proc. Zool. Soc. 1834, p. 63. Hinds 



in do. 1843, p. 166, no. 104. Hinds in Sow. Thes. Conch. 



p. 183, no. 99, pi. 45, f. 104. 

 Euryta aciculata, H. fy A. Ad. loc. cit. 



Two dead specimens alone of this shell were found by Mr. 

 Darbishire with Euryta fulgurata ; distinguished by long nodu- 

 lons 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. Mai. 1847, 



* " Our information of the W. Indian species is most barren," Hinds in Thes. 

 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. 8. Vert. vol. x. p. 250, no. 22) which is Buc. cinereum of Born, 

 (v. Desk, in loc.) and Terebra cinerea of Thes. Conch, p. 180, no. 87 : P. Z. S. 

 1843, p. 165, no. 93.
