base, the anterior portion only being free; parietal wall covered by a thick 
callus, which renders the peritreme complete; operculum typical. Altitude,

Barleeia dalli Bartsch, 1920 
Proceedings of the United States National Museum, 58:168; PI. 13, fig. 10. 
Shell rather large, broadly conic, yellowish white. Nuclear whorls two, 
well-rounded, marked by sinuous axial rows of closely spaced pits which 
are separated by spaces about four times as wide as the pits. Post-nuclear 
whorls almost appressed at the summit, moderately rounded, marked by 
slender, slightly retractively slanting incremental lines and numerous 
closely spaced spiral striations. Suture but slightly constricted. Periphery 
of the last whorl marked by a cord, which renders it decidedly angulated. 
Base moderately long and moderately rounded, marked like the spire. 
Aperture subcircular, posterior angle obtuse; outer lip thin at the edge; 
inner lip slender, evenly curved, appressed to the base, except at the 
extreme anterior portion, where it is free; parietal wall covered by a thick 
callus, which joins the columella with the outer lip at the posterior 
angle and renders the peritreme complete. The summit of the last turn 
bends slightly down below the peripheral cord near the aperture. Altitude, 
4.4; diameter, 2.4 mm. (Bartsch.)

Shell elongate-conic, pale chestnut brown. Nuclear whorls almost two, 
well-rounded, marked by curved, axial rows of pits, which are also 
arranged in spiral series. Post-nuclear whorls moderately well-rounded, 
almost flat at the summit, marked by fine incremental lines and exceedingly 
fine, closely spaced, spiral striations. Suture moderately constricted. Pe-
