PYRULA JUVENIS, Whitfield. PL 6, fig. 8. 



Pyrula juvenis, Whitf. Am. Jour. Conch., vol. I., 1865, p. 259. 



Pyrula multangulata, Heilpr. P. A. N. S., 1880, p. 374, pi. 20, fig. 2. 



Hitherto unfigured. Prof. Whitfield has kindly furnished me with a 

 drawing of the type. Common in the lower Tertiary, Bell's Landing, 

 Gregg's Landing, Nanafalia Group, Matthews' Landing and Woods' Bluff. 

 It is subject to considerable variation, and is probably the same species 

 quoted by Prof. Heilprin from Woods' Bluff, Ala., as Pyrula tricostata, 

 Desh. 



PYROPSIS FERULA, n. sp. PL 3. fig. 4. 



Shell depressed above, spinous ; whorls seven ; spire flat, showing only 

 the upper part of the whorls ; suture partially concealed by the spines of 

 the next succeeding whorl overlapping. 



Surface covered with strong, transverse, raised, cordlike lines, which 

 are armed with short, erect spines on the canal, becoming obsolete at its 

 base. Spines erect, closed, flaring upward and circling the periphery of 

 the body whorl, the one nearest the aperture being the largest. Aperture 

 ovate ; outer lip cut by the transverse lines, smooth within ; labium 

 strongly reflected, smooth, suddenly expanding at the anterior end of 

 aperture ; callus becomes thick in old specimens ; canal long and narrow. 



Locality. Wood's Bluff, Ala., in lower bed; also Matthews' Landing, 

 Ala. 



The largest specimen, if perfect, would be (2") two inches broad and 

 over (4") four inches long. 



PISANIA? DUBIA, n. sp. PL 3, fig. 13. 



Shell fusiform ; whorls rounded, about eight in number ; spire acute ; 

 surface covered with equidistant revolving lines, which are broadly 

 rounded, the spaces between smooth. 



Lines of growth obsolete ; the embryonic whorls are smooth. Aperture 

 oblong-ovate ; canal moderate ; outer lip thickened and striate within ; 

 inner lip smooth, slightly excavated, thickened and angular at junction 

 with canal. 



Locality. Lower bed, Wood's Bluff. 



The absence of a callosity at the posterior end of the aperture makes 

 the generic place doubtful.
