5. Callophyllis Homhroniana, Kiitz., Sp. Alg. p. 746. J. Ag. Sp. Alg. v. 2. p. 303. Rhodymenia 

 Homhroniana, Mont. Pole Sud,p. 157. t. l.f. 2. Hookfil. et Harv. M. Ant. v. l.p. 186. t. 11. f. 2. 



Hab. Eoveaux Straits, Lyall. East Coast, Colenso. '-' A truly lovely Alga, sometimes two feet long," 

 Colenso. (Auckland Islands.) 



6. Callophyllis acanthocarpa, Harv. ; fronde basi cuneata palmatim vel subdichotome fissa vel in laci- 

 niis pluribus vage partita, laciniis patentibus ssepissime fimbriatis, fimbriis indivisis vel multindis aculeatis, 

 cystocarpiis marginalibus vel in nmbrillis immersis aculeato'-ecbinatis. 



Hab. On stems of Ascidia, Middle Island and East Coast, and at Cape Cooper, Lyall. East Coast, 

 Colenso. 



Of this we have seen but few specimens, and, notwithstanding their peculiarities, we almost fear that they 

 belong to a variety of 0. Homhroniana, from which species the present, if permanently distinct, will chiefly differ in 

 its aculeate conceptacles. 



Gen. LXXVI. KALLYMENIA, J. Ag. 



(J. Ag. Alg. Medit. p. 98. Harv. Phyc. Brit. t. 13. J. Ag. Sp. Alg. ii. 284. Euhymenia, Kiitz. Sp. Alg. p. 741.) 



1. Kallymenia Earveyana, J. Ag., Sp. Alg. v. 2. p. 288. Euhymenia Harveyana, KUtz. Sp. Alg. p. 743. 

 Hab. Blind Bay, Cook's Straits, Lyall. (Native of the Cape of Good Hope.) 

 A single specimen only, found by Dr. Lyall. 



Gen. LXXVII. GIGARTINA, Lamour. 

 (J. Ag. Sp. Alg. ii. 260. Harv. Ner. Bor. Amer. pt, 2. p. 174.) 



1. Gigartina pistillata, Lamour. /. Ag. Sp. Alg. v. 2. p. 264. Kiitz. Sp. Alg. p. 749. Mont. Pole 

 Sud, p. 119. Gigartina divaricata, Hook.fil. et Harv. Fl. Ant. v. l.p. 187. 



Var. /3. dilatata ; stipite mox compresso sensim applanato cuneato in frondem lato-linearem planam 

 dichotomam fiabellatam desinente, laciniis distiche pinnatis, pinnulis divaricato-patentibus basi angustatis 

 acutis vel obtusis. 



Var. 7. ermacea j fronde applanata dichotomo-flabelliformi et distiche pinnata ramulis numerosissimis 

 capsuliferis utrinque densissime echinata. 



Hab. Several localities round the coast, Colenso, Lyall. (Native of South of Europe; and of Corn- 

 wall, England, in one spot only.) 



Had we not a suite of specimens connecting these very remarkable varieties with the ordinary state of the 

 species, which also occurs, but seemingly more rarely, at New Zealand, we should not have ventured to bring together 

 plants which at first sight are so different. Our variety dilatata, in its broadest state, has segments fully half an 

 inch in breadth, and quite flat. Though our specimens of 67. divaricata are few and imperfect, we fear they must 

 be referred to one of the varying forms of the species. 



2. Gigartina Chapmanni, Hook. til. et Harv. ; fronde teretiuscula filiformi siccitate compresso-canali- 

 culata alterne decomposita ramosissima, ramis flexuosis vage divisis, ramulis sparsis subulatis divaricato- 

 patentibus. (Tab. CXIX. B.). 



Hab. Maketu, Chapman. 



We have seen but a solitary specimen, and should probably have referred it to 67. acicularis, but that the frond 

 is much more slender, not much thicker than hog's-bristle, and much more branched than in any state of 67. aciculark
