DRILLIA. 209 



Martens describes a var. Magellanica, differing only in being 

 half the above size. 



D. STUDERIANA, Martens. PI. 13, fig. 48. 



Shell stouter than the preceding species, with shorter body- 

 whorl ; the ribs stronger and fewer, evanescent on the body-whorl, 

 the revolving lines slighter, scarcely apparent ; canal shorter and 

 broader. Length, 22 mill. 



Kerguelen Island. 



D. LOPRESTIANA, Calcara. PI. 13, figs. 66, 59. 



Whorls seven, with revolving carinae, the interstices longitu- 

 dinally striate ; sinus wide ; whitish, apex brown-stained. 



Length, 8 mill. 



Mediterranean Sea. 



V. cri^ata^ as figured by Reeve (fig. 59), is a sj-nonym ; as 

 well as several other specific names, some of which are for fossils ; 

 Tarentini, Phil., Renieri, Scacchi, moniliger, Cantraine, tri~ 

 cinctum, Calcara, Trecchi, Testa. 



D. KENNICOTTI, Dall. PI. 13, fig. 69. 



Shell solid, white, with traces of thin yellowish epidermis ; 

 no longitudinal ribs ; lip deeply excavated below the suture, 

 margin thin and sharp; columella twisted. Length, 21 mill. 



Unga Island, Shumagin Group, Alaska. 



Much resembles PI. declivis, Martens, from Japan. If identi- 

 cal, the latter name will become a synonym. 



D. CORUSCA, Reeve. PI. 13, fig. 60. 



Shell rather pyramidal, highly polished ; upper portion of the 

 whorls flat, clouded with reddish brown and white, lower portion 

 more prominent, encircled with a row of irregular reddish brown 

 dots, last whorl encircled with two rows of dots ; aperture 

 short; canal very short. Length, *75 inch. 



Philippines (Cuming). 



Two specimens only of this singular shell were obtained ; it 

 differs much from the ordinary type of Drillia, the form being 

 more like a Daphnella, but it appears to be a thick species. 



D. VEXILLUM, Reeve. PI. 13, fig. 72 (f ). 



Shell closely ribbed, and with revolving ridges at the base ;
