Material examined.

20 spm (13 × 6 - 25 × 12 mm).

Synonymy.

See Dell (1971).

Remarks.

Aldea and Rosenfeld (2011) commented that, differing from other species of the family Buccinidae , it is characterized by direct development during its reproductive cycle by depositing egg masses ( Pastorino and Penchaszadeh 2002). Dell (1971) explained that Strebel (1905b), when revising the species of the genus Pareuthria , observed a great similarity between Pareuthria plumbea and Pareuthria magellanica ; however, the original figures did not concur with the distinction that was made by Strebel (1905b).
