194 MR. E. A. SMITH ON MOLLUSCA FROM JAPAN. [Feb. 18, 



tionally much larger ; the form is less robust, and the colouring is 

 different in detail. 



27. Drillia flavonodulosa. (Plate XIX. fig. 21.) 



Shell solid, ovately fusiform, pale fleshy white, banded with yellow 

 on a series of nodules around the lower half of the whorls, stained 

 with reddish brown between the nodules, with a second series of 

 yellow gemmules, with a reddish-brown lira beneath it, situated a little 

 below the middle of the body-whorl. Whorls 7^, apical ones large, 

 the rest undulately carinated above at the suture, then concave, 

 coarsely ribbed and spirally lirate ; two of the lirso (in all six in 

 number) are vastly stouter than the rest, and on crossing the ribs 

 form two distinct series of nodules around the lower part of the 

 whorls ; the other lirce above and belovv these are fine and thread- 

 like ; beneath the sutural wavy keel on the last whorl are three fine 

 lirEE ; then follow nine of the coarse nodulous ones ; and around the 

 basal extremity orcauda, which is brownish, are about six finer ones. 

 Aperture small, a little more than one third the entire length of the 

 specimen ; labrum not thickened, rather deeply sinuated ia the con- 

 cavity at the upper part of the whorl ; columella smooth, a trifle 

 oblique, very shghtly tortuous, covered with a moderately thick livid 

 enamel ; canal -sery short. 



Length 9 5 miUims., width 3.

This is a solid species, peculiarly coloured, and readily known by 

 the coarse granules. It belongs to the same group as P. inconstans, 

 another Japanese form described by me iu the Ann. & Mag. Nat. 

 Hist, in 1875. 



28. Drillia fortilirata. (Plate XIX. fig. 22.) 



Shell elongated, horny or dirty white, stained with brown or pur- 

 plish brown at the extremity of the last whorl. Whorls 12, a little 

 convex, rather coarsely clathrated by longitudinal costse and trans- 

 verse ridges ; costos a little oblique, rounded, ten or eleven on a whorl ; 

 spiral lirse very prominent, compressedly subnodulons on crossing 

 the ribs, undulating or festooned, five or six in number, whereof the 

 uppermost (which borders the suture) is especially developed ; last 

 whorl concave below the middle, at which point the ribs terminate, 

 and encircled by about nine fine thread-like lirse. Aperture small, 

 brownish witliin, equalling about two sevenths of the entire length of 

 the shell ; labrum tliickeued by the last costa, lirate internally, with a 

 small sinus a little below the suture; columella coated with a thin 

 brown callosity, obliquely sinuous, smooth, without lirse or granules ; 

 canal short, oblique, faintly recurved, broadish. 



Length 14 millims., width Sg. 



Hab. Stations 21 and 14. 



The lirte within the lip may not be a character of much specific 

 value, as they are only observable in one of tlie four specimens 

 before me.
