The cosmopolitan species C. tomentosum has been divided into several sub- 

 species by various writers, especially Agardh {loc. cit.). It is impossible to say to 

 which of these the Auckland Island form should be assigned, as no specimens of 

 it were brought home by us. It doubtless occurs at Campbell Island and the Snares, 

 though not observed by us at these places. The New Zealand species is termed by 

 Agardh (loc. cit., p. 43) Codium mucromatum, var. y novae-zelandiae.
