110 TRANSACTIONS OF THE WAGNER FREE 



of the body-whorl, and the subsutural impression. There is no trace of 

 coronation. The form is intermediate between Voluta proper and Lyria, 

 perhaps nearer to the latter. 



Voluta (Lyria) zebra, nov. sp. Fig. 46. 



Shell cylindriform, with an elevated, slightly scalariform spire of about 

 six volutions; whorls costated, the costs; (about twenty on the body-whorl) 

 closely-placed, sharply-defined, oblique, forming a pseudo-coronation on 

 top of the whorls ; outer lip greatly thickened on the border, slightly 

 ascending; inner lip irregularly plicated over its entire extent, the three 

 or four basal plica; much the strongest; aperture somewhat more than 

 half the length of shell, narrow, elliptical, contracted basally into a short 

 open canal ; surface of shell, barring the costse, smooth over almost its 

 entire extent, with a few impressed revolving lines on the base of the 

 body-whorl. 



Length, an inch and a quarter ; greatest width, .6 inch. 



This shell most nearly resembles Voluta pnlcliclla of Sowerby, a 

 Miocene fossil of Santo Domingo (Q. J. Geol. Soc. London, vi, p. 46, pi. 

 ix, fig. 4), but may be distinguished by its narrower spire, the greater num- 

 ber (best seen on the spire) and more direct obliquity of the costas, and 

 the costal coronation on top of the whorls. Exceptionally the costas are 

 equally crowded in V. pulchdla, but the regular convexity of the whorls, 

 and the absence of the subsutural coronation, seem invariably to dis- 

 tinguish that form. Much the same characters separate it from Otocheilus 

 (Fulgoraria) Mississippiensis of Conrad, from the Vicksburg (Oligocene) 

 group, which is also a narrower shell. In its ornamentation the Florida 

 fossil more nearly approaches the recent V. Delessertiana. 



Mitra (Conomitra) angulata, nov. sp. Fig. 47. 



Shell ovately cylindriform, longitudinally plicated ; whorls of the spire 

 very convex, slightly angulated above ; body-whorl more prominently 

 angulated ; revolving lines absent or obsolete, except from the base of 

 the shell ; aperture somewhat exceeding one-half the length of shell ; 

 columellar folds four, the upper nearly oblique. 



Length, .4 inch; width, .17 inch. 



Conus planioeps, nov. sp. Fig. 48. 



Shell broadly conical, rapidly tapering toward the base ; spire reduced 

 to a minimum, represented in most specimens by an exceedingly gentle 

 rise, crowned by a papilla (apex); whorls about seven, all of them fully 

 exposed on the crown, the shoulders concentrically lined ; revolving lines 

 nearly obsolete over the greater extent of the body-whorl, prominent on 

 the basal portion ; notch ? 



Length, 1.4 inches; width of crown, .8 inch.
