This little-known species has been known as "Odostomia" modest a [Chemnitzia inodesta Stimpson, 1851 not C. inodesta Orbigny, 1842] and "; dealbata (Stimpson, 1851) [a nomcn dubium}. Abbott (1974, p. 292) sug- gested that "; inodesta is 0. conoidca (Brocchi, 1814) but this European species differs. "; uwdesta of Bartsch (1909, p. 108, pi. 13, fig. 50) is "; gibbosa Bush, 1909 (Fig. 9). The holotype of Pyramiddla (SulcorineUa) bartsclu Wink- ley (1909, fig.), at the Museum of Comparative Zoology (no. 32810), shows that this was incorrectly described and illustrated ; the outer lip is broken back and there is no deep peripheral sulcus (Fig. 8). The shell was better illustrated by Bush (1909, fig. 6). F. bartsclu resembles the grooveless form of B. bisutnralis but differs in the characters shown in Table I, in having a dark, brick red, pigmented mantle organ instead of a yellow and brown one, in having a projecting excurrent siphon, and in having brown superficial spots behind the head, golden yellow spots elsewhere, and an operculum with a spiral sector that, superficially, is cream white. Prior generic assignments. "Odostomia" bartsclu has been classified in the sub- genus Odostomia Fleming, 1813, sensn stricto (Abbott, 1974, p. 292, as "; modesta), the type-species of which, 0. plicata (Montagu, 1803), of Europe, pre- sumably is one of the species with penial copulation (no spermatophores) studied by Fretter and Graham (1949).
