A species of Lessonia was observed at Enderby Islands. Fragments of a 

 Lessonia were also collected at Monument Harbour, Campbell Island, by Mr. J. 

 Crosby Smith. They are, unfortunately, in a poor state of preservation, but seem to 

 belong to the species L. variegata. I also noted the presence of L. variegata at the 

 Snares, but brought back no specimens. 



Macrocystis, C. Agardh, 1823. 



Distribution. — West coast of South America to the Galapagos, South California 

 to Sitka, Alaska, Ochotsk Sea, east coast of South America to 45° S. lat., Magellan 

 Straits, Falkland Islands, South Georgia, Cape of Good Hope (? growing), Prince 

 Edward Islands, Crozets, St. Paul, Kerguelen Land, south coast of Australia and 

 Tasmania, New Zealand, Tahiti (? growing).

Auckland Islands ; Hooker, R. M. L. Campbell Islands ; Hooker and Harvey, 

 R. M. L. (Distribution as for the genus.) 



The immense length formerly assigned to this well-known species was un- 

 doubtedly a mistake. Specimens of more than 100 ft. in length are very uncommon. 

 A variety with almost spherical bladders was observed at Monument Harbour, 

 Campbell Island, but unfortunately no specimens of it were brought to New Zealand.
