Abstract

In my previous paper (1954) I have noticed that Calanus plumchrus MARUKAWA is identical with Calanus tonsus BRADY. However, upon examination of the specimen of C. tonsus taken from the Antarctic C. plumchrus was proved to be a characteristic copepod of the North Pacific, and is d'stinct from C. tonsus BRADY of the Antarctic.
