Colours: Face opaque, mostly greyish white or cream, sometimes yellowish or pinkish white. Channels (grooves and pits) usually taken up ± completely by the rubrications, and difficult to distinguish from them, therefore seldom perceptible as greenish to reddish brown. Rubrications often obscure, dull orange-brown to orange-red. Shoulders as for the face, or very slightly lighter.
Size: Small to large, facial diameters up to 38 X 27 mm, mostly about 25 x 20 mm. Number of heads up to 30 or more, mostly 2-5.
