Laing. — On the Algce of New Zealand. 30t 



Professor T. J. Parker, I have seen one of the type specimens, 

 and I find that the plant is epiphytic on the well-known Alga, 

 Lycluetc {Conferva) clarwinii, Kuetz. This being somewhat 

 decayed has perhaps caused it to be mistaken for molluscan 

 eggs. Professor Gibson's list contains fifteen species which 

 are not included in that of Agardh. Of these, the majority 

 are Australian forms, not previously recorded from New 

 Zealand. In one or two cases I am by no means certain of 

 the synonymy, so that this number may not be quite accurate. 

 I attach a list of them to the end of this paper. Special men- 

 tion should perhaps be made of Microcladia coulteri, as the 

 genus is here recorded for the first time from the Australian 

 region. I have for the last two years been aware of the 

 existence of this genus in New Zealand, but have not an- 

 nounced it, as I was not sure that our plant was specifically 

 identical with the Californian M. coulteri (Harv.). If it be 

 the same, the plant must be variable. I have specimens of 

 this genus from Taylor's Mistake, and I have also received it 

 from Dr. Chilton, of Port Chalmers, who obtained it at Long- 

 beach, North Otago Heads. 



Our list of New Zealand marine Algas will now comprise 

 307 species, omitting the Protophycece. It is made up as 

 follows : Agardh's list, 275 ; Corallines, 12 ; Harvey Gibson's 

 list, 15 ; sundry, 5 : total, 307. 



Those marked "Sundry" include Grijfithsia sonderiana 

 (J. Ag.), Ceramium stichidiosum (J. Ag.), Asjxiragopsis armata 

 (Harv.), Landsburgia myricifolia (J. Ag.), Ulva bullosa (Roth.). 

 Grijfithsia sonderiana should probably replace G. setacea of 

 Agardh's list; but I retain both for the present. The next 

 thre'e mentioned are probably accidental omissions from 

 Agardh's list. Ulva bullosa appears in Hooker's Handbook, 

 with a (?) attached, and no habitat is given. It is omitted 

 altogether from Agardh's list. I have, however, specimens of 

 what is doubtless Hooker's plant, collected by Mr. T. Kirk, 

 F.L.S., at Eocky Nook, near Sinclair Head, and by myself at 

 Oriental Bay, Wellington. It must be remembered that the 

 morphology of most of our species is not only known, but 

 their fructification and internal structure have also been mi- 

 croscopically examined.* Of course, much still remains to be
