mitted to include a land shell in this marine deposit one might suspect 

 it to be one of the lamellose Vallonias. 



CYMATIUM CECILIANUM, new species. 



Plate 85, fig. 10. 



Shell small, thin, of about five whorls excluding the (decollate) 

 apex, with a few thin, almost sharp varices irregularly disposed; 

 suture distinct, not channeled; early whorls with two sharp revolving 

 ridges, subequal, forming the periphery; within the excavated but 

 not channeled interspace a single small spiral thread; m the space 

 between the sutm'e and the first ridge there are three or foui* threads, 

 the first, well separated from the suture by an excavated but not 

 channeled interval, is a little more prominent and sharper than the 

 others; in the narrower space between the second ridge and the 

 suture m front of it are one or two fine threads; the last whorl 

 between the suture and the canal are seven or eight prominent rather 

 sharp ridges, the two near the periphery most prominent; all are 

 acutely nodulose, where they cross the varix and are separated by 

 subequal interspaces which carry two or three fine spiral tlireads in 

 each; the canal is almost straight and obliquely spirally closely 

 threaded; there is no callus on the inner lip in the specimen, which is 

 probably somewhat immature; the outer lip is wanting. Length of 

 decollate five whorls, 25; of last whorl, 17; diameter of last whorl, 

 about 14 mm. 



Locality. — Station 7074, on the west bank of Flint Kiver, 7 miles 

 southeast of Bainbridge, Decatur County, Georgia, at Hale landing, 

 in coralliferous chert; Vaughan, Cooke, and Mansfield, 1914. U. S.

BURSA VICTRIX, new species. 



Plate 88, fig. 10. 



Shell of moderate size, the apex wanting, the type-specimen cast 

 from a mold comprising tliree whorls, with discontinuous lateral 

 varices two to a whorl; the varices are rounded and nodulous, the 

 sculpture harmonizing with the spiral sculpture of the roundly 

 inflated whorls; the suture is distinct, not channeled. The sculpture 

 comprises on the last whorl a smooth interval sloping from the 

 suture; then a sparsely prominently beaded cord; then a wider 

 interval carrying a less prominent and less distinctly beaded cord, 

 followed by a simple spiral thread; then a broad band forming the 

 shoulder of the whorl and carrying about a dozen semiglobular promi- 

 nent nodulations, the whole sharply spirally striated; in front of this 

 two subequal and equidistant narrower bands similarly but more 

 closely and feebly nodulous and striated, in front of which on the 

 preceding whorls the suture is laid. The base shows two minutely
