Vaisikorid^. 



172. VAinKORO CANCELLATA, Lam. 



A smooth variety, exhibiting hardly any dorsal cancellation. 

 It is the type of the genus, named after the Island Yanikoro 

 iu the Pacific Ocean. The name, though barbarous, should, in 

 our opinion, be retained, as the genus was definitely described 

 by Quoy and Graimard in 1832, thus having precedence over 

 Merria, Gray, 1839 ; and a yet longer period over Leucotis, 

 Swainson, 1840, and Narica, Eecluz, 1841. 



* Mr. 0. Hedley, in his MoUusca of Funafuti (Mem. Austral. Mus. iii. p. 43, 

 1899), makes our A. pyrrhacme the type of his new genus Obtortio.
