Shell moderately long, whorls but slightly impressed, almost 
evolute; transverse section elongate-oval, abruptly rounded at 
the dorsal and ventral extremities, and nearly flat on the sides, 
Surface of shell apparently smooth, Septa rather remote. Dor-

breadth of its base; first lateral lobe clavate, acute, twice as

transverse section. It differs from @. 
Lyoni Meek and Worthen, in the greater relative length of the 
second lateral lobe and the first accessory saddle, as also in the 
More appressed transverse section. Its closest affinities are with

and relatively longer lateral and accessory saddles.
