Odostomia kennerlyi Dali and Bartsch, 1907 
Plate 64, fig. 8 
Proceedings of the United States National Museum, 33:529; PI. 48, figs. 8, 8a. 
Shell large, very thin, broadly conic, umbilicated, yellowish-white; 
marked by subobsolete, subequal, and subequally spaced spiral wrinkles, 
about fifteen of which may be seen on the body and base of the last whorl. 
In addition to these wrinkles, many faint, closely placed spiral and vertical 
striae are present. Nuclear whorls small, about two and one-half, forming 
a depressed spire which is deeply immersed, the axis of which is almost 
at right angles to the axis of the later whorls. Post-nuclear whorls very 
wide, inflated, well-rounded, faintly shouldered at the summit. Suture 
well-marked, simple. Periphery and base of the last whorl inflated, well- 
rounded, the latter decidedly contracted and narrowly umbilicated. Aper¬ 
ture large, suboval, somewhat effuse anteriorly; posterior angle obtuse; 
outer lip thin; columella straight, obliquely inserted, revolute, not re¬ 
enforced by the base, with an oblique weak fold near its insertion; parietal 
wall apparently without a callus. Length, 10.2; diameter, 6 mm. (Dali 
and Bartsch.)

Martini and Chemnitz, Conchylien Cabinet, 2d ed., Pyramid, 115; PI. 28, fig. 1. 
T. conica, vix rimata, glabra, solida, opaca, albida, nitens; spira curta; 
anfractibus 6 lente et regulariter accesceptibus, parum convexis, sutura 
profunda separatis; ultimus ad basin rotundatus; apertura one-third long, 
testae superans, ovata, superno acuminata, labro acuto, arcuato, columella 
contorta, dente acutissimo raunita; labio angusto. Long., 10; diameter, 
4.5 mm. (Clessin.) 
Shell elongate-conic, thick and heavy, rough through erosion, yellowish- 
white. (Nuclear whorls decollated in the type; judging from the pit in 
the apex they are probably deeply, obliquely immersed.) Post-nuclear 
whorls only moderately rounded, somewhat shouldered at the summit (sur-
