224 TRANSACTIONS OF THE WAGNER FREE 



This elegantly sculptured little species differs from G. Watsoni in its 

 larger size and simply alternated spiral sculpture on the anterior part of the 

 last whorl, and in minor details of the mouth-sculpture. G. incilis is nearly 

 twice as large, beside having a quite different sculpture, and none of the 

 recent species seem to approach the present species closely. It is named in 

 honor of Mr. Chas. W. Johnson, Assistant Curator of the Museum of the 

 Wagner Free Institute of Science, who collected it.

Mr. Willcox has collected at Magnolia, Duplin Co., North Carolina, from 



the newer Miocene, some fine specimens which appear to be referable to a 



variety of this species which may take the name rotunda. They agree in all 



essentials with the Pliocene C. Co?iradia7ia and the recent rctiadata Linne, 



except in relative height. In this respect they are intermediate between the 



two, being taller than the tallest recent specimens and shorter than the C. 



Conradiana. The largest specimen is larger than any specimen either of 



reticulata or Conradiana I have seen. It measures 66.25 '^'^- ^ongi 35-0 n^™- 



in maximum diameter, and exhibits nine whorls, without the nucleus.

Pliocene of Shell Creek and the Caloosahatchie, Dall and Willco.x. 



Shell of moderate size, strong, scalar, of six whorls, including a rather 

 irregular, smooth nucleus of one and a half whorls; spiral sculpture of little- 

 elevated, flatfish, close-set threads consisting of primaries (about eight between 

 the carinse of the last whorl), separated by somewhat smaller secondaries in 

 sets of three, alternated with very minute tertiaries toward the last, which are 

 absent on the earlier whorls, where the number of secondaries also becomes 

 gradually smaller ; the difference between primaries and secondaries is not 

 very marked ; the transverse sculpture, apart from fine incremental lines, is 

 confined to a few strong, irregularly placed, rounded varices, angulated some- 

 what at the carinje. The type-specimen has six of these, that at the aperture 

 being close to the next preceding, but separated by half a turn from the next 

 earlier; whorls rounded at the sides, strongly carinated before and behind and
