The umbilical shoulder is abruptly rounded, the flanks broadlyrounded and convergent, merging with a broadly rounded venter. Ornamentconsists of fine transverse growth striae and longitudinal ridges which combineto produce a reticulate pattern which is particularly conspicuous on the transverse striae arise at the umbilical seam, pass straight up the umbilicalwall with a shallow concavity, are slightly prorsiradiate and weakly convex acrossthe flanks, and sweep backwards across the ventrolateral shoulders to form ashallow, broad ventral sinus. The suture consists of a broad, short, moderately subdivided spatulateventral saddle, a massive, highly subdivided bifid firs
