About Phyllonotus pomum (Gmelin, 1791)
The adult shell of Phyllonotus pomum ranges in size from 44 mm to 133 mm. The original description published by Lovell Augustus Reeve in 1843 characterizes the species as follows: The shell is fusiformly oblong, thick, solid, and very rough across its entire surface. It has prominent transverse ridges, with tubercles located between its varices. The shell is three-varicose; the varices themselves are tuberculated with a complicated mass of laminae. The shell color is fulvous or reddish brown. The columella and the interior of the aperture are ochraceous yellow. The columellar lip is slightly wrinkled, with an erected edge that bears a vivid, very dark brown stain, most intense at the upper part. The outer lip is strongly toothed, and marked with three dark brown spots. The siphonal canal is rather short, compressed, and recurved. This species is distributed in the Caribbean Sea, the Gulf of Mexico, the Lesser Antilles, and in the Atlantic Ocean between North Carolina and Northern Brazil.
