Cythara psila Bush. 



Mangilia psila Bush, Trans. Conn. Acad. vi. p. 455, pi. xlv. fig. 2, 1885. 



Caloosahatchie beds. Recent off the coast of the CaroHnas in 16 to 50 

 fathoms. 



Cythara terminula n. s. 

 Plate 2, figure 5. 



Caloosahatchie beds, rare. 



Shell acute at both ends, seven-whorled ; nucleus minute, smooth ; later 

 whorls transversely sculptured with nine narrow, rather sharp uniform ribs ex- 

 tending from suture to canal in a nearly straight line, and but little stronger 

 on the periphery than elsewhere ; there are also fine, sharp incremental lines, 

 most marked in the spiral furrows; spiral sculpture of numerous rather uni- 

 form flattened bands separated by sharp, much narrower channels, and marked 

 by a central impressed line less deep and wide than the channels, but giving to 

 the bands the look of running in pairs ; suture appressed and inconspicuous ; 

 whorls fuller near the suture in front than at the middle of the whorl, and 

 rather depressed in front of the suture, though not marked by a fasciole there ; 

 last whorl much the largest ; aperture long and narrow ; notch inconspicuous, 

 canal not differentiated ; callus smooth on the pillar and smooth or slightly 

 striated by the sculpture, inside the outer lip ; varix stout and wide. Max. 

 Ion. of shell 16.0; of last whorl 12.5 ; max. lat. of shell 6.7 mm. 



Subgenus Daphnella Hinds. 



Daphnella cingulata n. s. 



Plate 2, figure 3. 



Rare in the Caloosahatchie beds and at Shell Creek, Florida. 



Shell slender, eight or nine-whorled ; nucleus small, smooth, three-whorled ; 

 subsequent whorls spirally sculptured with larger and smaller squarish elevated 

 threads, which, on the last whorl, tend to be alternately strong and weak ; the two 

 series are remarkably uniform among themselves, except that on the periph- 

 ery two or three of the primary threads will be a little more prominent than 

 the rest, while on the fasciolar region there are five or six uniform large sec- 

 ondary threads, close-set, without any primaries ; the transverse sculpture com- 

 prises on the earlier whorls eight or ten rounded riblets well defined near the 

 nucleus, but becoming less distinct and finally obsolete on the later whorls ; 

 the last whorl and a half has no trace of them ; whorls rounded, suture dis- 

 tinct, but not channelled or appressed ; incremental lines distinct, slightly 

 elevated, neatly reticulating the secondaries and beading the primaries ; aper- 

 ture elongate, rather narrow, not differentiable from the canal ; outer lip smooth 

 within, inner lip with but little callus ; notch wide, not very deep ; canal 

 hardly indicated. Max. Ion. of shell 15.5 ; max. lat. 6.5 mm.
