72. Zonaria sinclairii. Fl. Nov.-Zel., p. 218. 



This plant was originally described by Harvey from speci- 

 mens sent from New Zealand, but does not seem to have 

 been collected in New Zealand since. I have one of the 

 specimens distributed by Harvey, and think that it may turn 

 out to be only a form of Z . turneriana. A careful collection 

 of specimens of Zonaria in the neighbourhood of Wellington 

 would probably settle the point as far as New Zealand is con- 

 cerned. 



73. Zonaria velutina. Fl. Nov.-Zel., p. 218. 

 Com.mon in rock-pools between tidal limits. 



I have a very distinct species of Zonaria collected by Mr. 

 Crosby Smith at Dunedin. It may be the Victorian Z . canali- 

 culata, but it would be dangerous to name it from a single 

 specimen. 



Order Desmarestiaceee.

Order Pucacese. 



75. D'Urvillaa titilis. Fl. Nov.-Zel., p. 216. 



This plant as well as Macrocystis has generally been re- 

 ported to be abundant on the New Zealand coast. I was, 

 however, unable to find it at any of the places on the east 

 coast of the North Island already mentioned under Macro- 

 cystis. It is generally found on rocks exposed to the full force 

 of the breakers. 



76. Notheia anomala. Fl. Nov.-Zel., p. 215. 



Common ; parasitic on Hormosira, and very rarely on Fu- 

 codium (Phyc. Mem., Brit. Mus., part ii., Miss M. 0. 

 Mitchell). 



Miss E. Barton has finished an exhaustive research upon 

 this plant, which will be published immediately in the 

 " Transactions of the Linnsean Society." 



77. Hormosira hanksU, Harv., Fl. Tasm. 



a. lahillardieri. Fl. Nov.-Zel., p. 215. 

 Everywhere common between tidal limits. 

 /3. sichcri. Fl. Nov.-Zel., p. 215. 

 In tidal pools near high-water mark. 



78 Fucodium chondrophyllum, J. Ag. {Xiphophora chondro- 

 phylla: Fl. Nov.-Zel., p. 215). 

 Common on tidal rocks in exposed situations. ,
