Nautilus, 39:25. 
Shell small, solid, subcylindric, white, with three and a half whorls; 
suture narrow, channeled; spire short and rather blunt, the specimen has 
the entire surface decorticated, so that the surface characters cannot be 
definitely described, but indications are that the incremental lines are 
rather rude and irregular; the base is rounded, with a deep chink, almost 
an umbilicus behind the anterior portion of the inner lip; the shell is very 
slightly constricted medially; the aperture is narrow behind, the posterior 
commissure rounded, falling short of reaching the suture; the anterior 
part of the aperture is wide, rounded evenly into the pillar lip, which 
shows no plait; the entire lip is thin and sharp, with a thin layer of enamel 
on the body. Length of shell, 8.5; of aperture, 6.5; maximum diameter, 
4.5 mm. (Dali.)
