Shell small, white, solid, with seven whorls and a very small brownish 
nucleus of a whorl and a half; varices nine or ten, low, sharp, reflected, 
anteriorly axially striated, with a very small sharp spine at the shoulder; 
suture deep, the whorls almost separated, rounded; base rounded, im¬ 
perforate ; aperture short-ovate, its inner margin resting on the preceding 
varices, not touching the body of the whorl. Length, 10.5; diameter, 
4 mm. (Dali.)

Plate 31, fig. 3 
Canada, Department of Mines, Geological Survey Branch, Memoir No. 14-N :13 ; 
PI. 1, fig. 1. 
Shell small, rather conic, white, with thirteen broadly reflexed, axially 
conspicuously striated varices; nucleus lost(?) ; whorls, more than six, 
varices continuous up the spire, narrow near the suture, more than dou¬ 
bling in width at the shoulder, where they are provided with a small 
spine or prominent angulation, then continuing to the base, where they 
are again narrowly contracted; there is no basal cord or disk, the um¬ 
bilicus is closed; the surface of the whorls between the varices is smooth; 
the whorls are evenly rounded, and the aperture, if perfect, would prob¬ 
ably be nearly circular. Length of six whorls (decollate) 9.5; diameter 
at base, 5.0; at decollation, 0.7; of aperture, 2.0 mm. (Dali and Bartsch.)

Epitonium rectilaminatum Dali, 1907 
Nautilus , 20 :127. Proceedings of the United States National Museum, 53 :482. 
Shell very similar to S', berryi, with the same number of whorls and 
varices, but having the nuclear shell smaller, the test less heavy, the varices 
nearly vertical to the surface of the whorl, instead of reflected which 
makes them appear sparser, though really the same number occur on
