Shell very small, broadly ovate ; spire less than half the height of 
aperture ; whorls 43, slightly convex on spire ; suture tangential ; aperture 
semilunar ; outer lip almost straight, antecurrent to suture ; inner lip with - 
fairly thick callus, which has a convex parietal boundary and is much wi 
over umbilicus, where it coalesces with funicle and generally completely - 
fills the opening. S
