EUGLANDINA. 177 



3. E. TRUNCATA (Gmelin). PL 21, figs. 4, 10, 11, 12. 



"A thin, uniform white shell, with the appearance of a 

 land snail. It is composed of 7 whorls and is similar in 

 form to the preceding [Liguus] but more lengthened. The 

 whorls are somewhat convex, the uppermost forming an ob- 

 tuse apex. The aperture is not very wide, its length more 

 than twice its breadth, and almost half the length of the shell. 

 The columella runs far forward in a strong curve, and forms 

 a channel, of which its truncate end is the outlet. The 

 growth-marks are very noticeable. They pass over the whole 

 shell, like fine striae, and their end points are cut off as by a 

 seam at the foot of the whorls, forming small notches. The 

 shell is 2 inches 6 lines long, and nearly 1 inch wide. ' '

Grinelin's name B. truncata was based solely upon the de- 

 scription and figure of Kammerer. The former is reproduced 

 above. The figure is a very good representation of what Al- 

 bers called G. subvaricosa. The dimensions given by Kam- 

 merer are almost exactly those of Albers' type. B. truncata 

 has been thought to apply to the Floridian species (E. rosea 

 Fer.), but the shape of the spire and columella, and the cre- 

 nated suture, show that it was based upon the South Amer- 

 ican species, and certainly not upon the Floridian. 



The shell is unusually thin, light dull-brown, with a few 

 former growth-stages marked by pale or whitish streaks, and 

 sometimes followed by darker brown streaks. The first whorl 

 is quite planorboid above ; the next has a characteristic form, 

 having a narrow shoulder and then flatly sloping outward.
