galeate |
= galeiform, helmet-shaped |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also cucullate (cuculliform, hood-shaped), which overlaps conceptually. |
