164 TURRICULA. 



formerly assigned to it a position between Conus and Mitra. 

 The animal was first made known to science by Mr. A. Garrett 

 in 1872,* who, after a careful study could not detect any 

 difference between it and a Cylindra. On plunging a living 

 example in alcohol, the spirit became much discolored, of a fine 

 purple, the same as when any other Mitridae are placed in 

 spirits. 



D. PHILIPPII, Crosse. PI. 47, fig. 381. 



Yellowish brown, or whitish, clouded with chestnut in the 

 form of two interrupted irregular bands. Length, 1-1*75 inches. 



Polynesia ; Mauritius. 



The earlier specific name D. edentulus, Swainson, has been 

 displaced because the character indicated by it has become 

 generic. 



Genus TURRICULA, Klein. 



The Turriculae, including the old sections Costellaria and 

 Callithea, are sand species ; the section Pusio, however, contains 

 reef-dwellers. The group is exclusively tropical and subtropical 

 in distribution, its metropolis being Central Polynesia. 



T. BEGINA, Sowb. PI. 48, fig. 382. 



Whitish or gray, with orange bands bordered by narrow 



chocolate-colored stripes. Length, 2-3 inches. 



Moluccas. 



T. TVENIATA, Lam. PI. 48, figs. 383-390. 



Yellowish or orange, with a broad white central band, partly 

 visible on the spire, bordered with narrow chocolate bands ; one 

 or two additional chocolate bands below, sometimes replaced by 

 a single broad one next below the white. 



Length, l'75-2'75 inches. 



Philippines, Moluccas, Polynesia. 



Has not the sharp angulation of the whorls of T. regina, but 

 is otherwise closely allied to that species. T. vittata, Swainson 

 (figs. 384-386), does not present any permanently distinctive 

 characters, and scarcely merits the name of variety, j". <-<n- 

 pressa, Sowb. (fig. 387), is a narrow variety, not adult; like, all
