Family COhUD.K. 

 Conus (Hermes) mitratus Bruguiere. — One beautiful and 



finely-marked specimen. Occurs also in the Philippines. 

 Drillia cygnea M. & S., p. 379, 1897. 

 D. ione M. & S., p. 277, 1896. 

 D. Mariesi Souverbie. — One specimen of a neat dark-brown 



shell, elegantly noduled with white spiral beading, which 



agrees with specimens of M. Souverbie's species in our 



National Collection. From Uvea. 

 D. Rougeyroni Souverbie=D. barkliensis H. Adams.— 



Our three specimens are a little worn, but we think we are 



right in the identification. A dark-umber shell, spirally 



tomate, and noduled. 

 D. themeropis M. & S., p. 278, 1896. 



D. vidualoides Garrett. — A small and very pretty form, per 

 haps too nearly allied to D. vidua Rye. or D. unizo/ialis 

 Lam , with which latter it is united by some authors. 



D. xanthoporphyria M. & S., p. 278, 1896. 



D. (Clavus) formosa Reeve = D. lactea Hinds.— Of the 

 same character is D. vidua Rve. Recorded also from 

 various distant Polynesian stations. 



D. (Clavus) gibberulus Hervier. J. de Conch., vol. xliii., 

 p. 143, for 1895 (1896). — Many specimens of an elegant 

 smooth straw-coloured shell, with irregular prominent 

 longitudinal ribs. 



D. (Clavus) protentus Hervier.— Too near, in our opinion, 

 to D. vidua Reeve.
