generally considered as an abnormality, a variation of C. 

 vernalis. Professor Lilljeborg, in his definition of C. vernalis,

 compositae." Our only record is for the elongatus variety.

 The form described by Sars under the specific name 

 ahyssorufn seems to be simply a pelagic form of C. strenuus, 

 altogether more feebly developed, and generally found at

 of the strenuus form from Belsay, Plessey, Lambton Park, 

 and Seaton Carew. N.D.
