Description
This genus, almost entirely represented by extinct species, is of slender form and elevated, evenly and gradually acuminate spire, conspicuous development of the spiral lyrae and short aperture. It should evidently be considered especially with ''
Trypanotoma'' and allies, but it is somewhat of an annectant form, as the American species at least have true ribbing on the nepionic whorls which becomes completely lost on the larger volutions of the shell. It is therefore one of those puzzling exceptions which render an arrangement of the genera in a dichotomous table so difficult and unsatisfactory. The embryo in the type, ''Pleurotoma basteroti'' Desm., of the European
Miocene, is said by Cossmann to be paucispiral, but the drawing shows a multispiral protoconch. This is, however, a matter of minor importance. The
anal sinus is broad, sometimes very feeble and always median in position on the spire whorls though not identified with any particular one or more of the subequal and rather coarse flat spirals. The beak has no external oblique tumidity. There can be but little doubt, in view of geographical variations and wide distribution of this genus, that ''Endiatoma'', of Cossmann, should be regarded as a synonym or as constituting a slightly differentiated section of ''Asthenotoma''.
