Barleeia bentleyi Bartsch, 1920 
Proceedings of the United States National Museum, 58:168; PI. 13, fig. 2. 
Shell small, conic, flesh-colored, excepting the two nuclear turns, which 
are light brown. Nuclear whorls well-rounded, marked by curved axial 
rows of closely spaced pits, which are separated by spaces about one and 
a half times the diameter of the pits. Post-nuclear whorls moderately well- 
rounded. The appressed summit of these whorls falls slightly below the 
peripheral keel, and allows this to appear in the suture as a slender thread. 
The surface of the post-nuclear turns is marked by curved incremental 
lines and numerous fine, rather closely spaced, spiral striations. A strong 
cord marks the periphery and renders it decidedly angulated. Base mod¬ 
erately long, well-rounded, marked like the spire. Aperture large, posterior 
angle obtuse, slightly effuse at the junction of the inner basal lip; outer lip 
thin; inner lip slender, oblique, and appressed for the greater part to the
