Remarks. The outline of the specimens in this study is not lobulated as the specimen illustrated by Dawson (1860). They have a smooth outline as in the specimens from the Pacific illustrated by

Matsunaga (1963), Matoba (1967) and Vázquez

Riveiros and Patterson (2007), though a form with a lobulated outline has been recorded in the

Pacific, e.g., in the Japan Trench area ( Keller,

1980).
