192 EUGLANDINA. 



columella than most acknowledged species of the genus. The 

 sculpture, however, is much alike in all. The following vari- 

 eties have 'been proposed : 



E. rosea bullata (Gld.). Vol. I, p. 32. Var. abbreviata 

 Marts, and var. ovata Dall seem to be intermediate between 

 bullata and rosea. 



E. rosea (Per.). Vol. I, p. 32. 



E. r. parallela W. G. B. Vol. I, p. 32. 



E. r. minor W. G. B. 



E. r. macer Dall. 75x20 mm. Florida.

The shell is rather slender and long, thin, corneous, the 

 spire slender, rather straightly conic, apex obtuse. The apex 

 is small; first 2y 2 whorls convex, smooth; the later whorls 

 sculptured with striae which are thread-like on the spire, 

 wrinkle-like on the last whorl, quite unequal in size, some of 

 them enlarged at the suture, forming an irregular but rather 

 strong denticulation. Below the suture there are some faint 

 traces of spiral striae in places. Whorls 7, moderately convex, 

 the last more rapidly descending. Aperture small, vertical, 

 bluish-white inside. The outer lip arches forward in the 

 middle. Columella moderately concave, truncate as usual. 

 Length 39, diam. 14.5, length of aperture 18 mm. 



Texas, exact locality unknown. 



This species is represented in the collection of the Academy 

 by a specimen received from Mr. W. G. Binney under the 

 name G. texasiana, and another in the A. D. Brown collection 

 labeled G. albersi, both bearing the locality "Texas." It has 

 some resemblance to E. turris Pfr., but differs by the irreg- 

 ular and coarser sculpture. It is quite unlike E. texasiana in 

 sculpture and the shape of the spire, and I have 'been unable 

 to refer it to any Mexican speeies.

Shell long, rather slender, uniform chestnut- colored, very 

 glossy, rather thin but strong. Spire long, with slightly con- 

 vex outlines and obtuse apex. The embryonic shell consists
