Marine Algae.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 505 



I have also some specimens from the Antipodes collected by Dr. Cockayne, 

 and identified by Major Reinbold as P. nohilis (?), which may, I think, be well 

 included in the species. 



Porphyra columbina, Mont. 



Porphyra columbina, Mont., Voy. au Pole sud, Bot., i, p. 33, tab. 9, fig. 2, 1845. 

 P. laciniata. Hook. f. & Harv., Fl. Nov. Zel., ii, p. 264, 1855. P. cafensis, 

 Hook. f. & Harv., Handb. N.Z. Flora, p. 715, 1864. 



Auckland and Campbell Islands ; d'Urville, Hooker. (New Zealand.) 

 This species, originally described from the Auckland and Campbell Islands, is, 

 I believe, common on the New Zealand coast. It, however, does not appear 

 to have been collected either by Mr. Smith or myself during the " Hinemoa " 

 expedition.
