The columella is arcuated towards the middle, furnished with a wide, reddish, and almost circular callosity, which extends upon the body of the body whorl.

The entire plant is more or less resinous, and the dark-brown bark has numerous warty excrescences and is easily wounded, producing large callosities as it heals.

The columella is arcuated, covered by the inner lip, which is enlarged into a whitish, wide, and thick callosity, upon the body of the lbody whorl.

Leaves that have grown callosities, which strongly resemble the orange eggs of the butterfly, are less likely visited by egg-laying females, protecting the plant from herbivory.
35.
The short columella, sinuous in its middle, is covered by the left lip, which is pretty thick, and partially conceals at its base a grooved columellar callosity.

The whales are not beautiful _ their massive heads are covered with white growths called callosities _ but they are an awesome sight, up to twice the length of the boat.

Its color is light brown, with a narrow white zone a little below the middle of the columella is covered with a pale brownish callosity and tuberculated at the upper extremity.

Males have been observed scratching one another with their callosities and it has been suggested by Payne & Dorsey ( 1983 ) that this is a sexually dimorphic feature used for intra-specific sexual aggression.
