The shape of muscle bellies was predominantly flat topped (26.7%), mammillated (20%) and interlinked (20%).
Muscle bellies were predominantly interlinked (26.7%), mammillated (13.4%), flat topped (10%) and H-shaped (10%).
Single head ALPM were predominantly flat topped and mammillated types in the present study while in the other study, (8) the predominant shape was conical and mammillated (Table 5).
Diagnosis: Shell globose without brown zigzag markings, spire low, apex globose to mammillated
, and protoconch without a calcarella.
As the thickening increases the skin lines are further accentuated and the surface becomes mammillated
or rugose and larger warty excrescences develop.
Lot 1792 "Mammillated
cupriferous Zinc, fine and rare, Nertschinsk" turned out to be aurichalcite on gossan, but there is still no sign of the intriguing Lot 2384 "An Aquamarine, one half rose red the other green, Ceylon, considered one of the rarest mineral substances." It is probably a cut stone and an investigation of the Chatsworth jewels may be revealing.
