young the line just outside of the umbilical carina is very 

 deep and wide; just outside of this furrow there is a second 

 deeplj'-beaded band separated from the rest of the base of the 

 whorl by a second but less deeply incised line. In young speci- 

 mens the umbilical carina projedls downward far below the peri- 

 pheral margin of the body whorl. 



I overlooked Ball's description (without figure) of this species 

 given in his "Tertiary Fauna of Florida" and gave another 

 name, syhisrupis. In part IV. of Ball's work, just published 

 (1898), I find it figured. It is true that a fossil is not now en- 

 titled to a name in scientific literature until it is figured. But in- 

 asmuch as Ball refers to a plate and figure in his earlier work, 

 this is taken as proof that a figure was drawn then, though pub- 

 lished in 1898. Courtesy would doubtless therefore permit the 

 use of the name 6*. louisiand.

Specific charane7'izatio7i. — Size and general form as indicated 

 by the figures; the spire depressed, though not so concave as the 

 under or umbilical side of the shell; costse somewhat irregularly 

 placed and at their jundlion with the spirals becoming somew'hat 

 nodular, especially on the uppermost and lowermost portions of 

 the body whorl; the latter very slightly carinated above.
