Hab. Otago and Euapuke, Lyall. Hawke's Bay, Golenso. Tauranga, Bavies. (Native of temperate 

 and tropical oceans.) 



2. Gracilaria multipartita, var. polycarpa, Grev., Harv. Phyc. Brit. 1. 15. /. Ag. Sp. Alg. v. 2. p. 600. 

 Sphserococcus polycarpus, Grev. Crypt. Scot. t. 352. Eucus granateus, Turn. Hid. t. 215. 



Hab. Blind Bay, Cook's Straits, Lyall. (Native of temperate and tropical oceans. Eare in England.) 



3. Gracilaria coriacea, Harv. ; stipite brevi mox cuneato in frondem planam carnoso-coriaceam dieho- 

 torno-flabelliformem desinente, laciniis cuneatis diehotomis vel vage fissis margineqne nonnunrpiam folioli- 

 feris, axilhs rotundatis apicibusque obtusis, conceptaculis numerosissimis per frondem sparsis depresso-hemi- 

 sphsericis semi-immersis umbilicatis poro magno pertusis.— Ehodymenia ? coriacea, Hook. fil. et Harv. in 

 Bond. J. Bot. v. i.p. 545. 



Hab. Lyall' s Bay, Cook's Straits, and Bay of Islands, Lyall. 



This resembles 67. multipartita in habit, but is very much thicker, more coriaceous, and minutely wrinkled when 

 dry. The conceptaclcs are deeply sunk in the frond, much depressed or umbilicate at the apex, with a small, basal 

 placenta, from which rise innumerable spore-threads. These, in our specimens, break up into innumerable minute 

 spores, more like those of a Ehodymenia than of a Gracilaria, but we suspect that they are immature or abortive. 



Gen. LX. CALLIBLEPHAEIS, Kiitz. 

 (Kiitz. Phyc. Gen. p. 403. Sp. Alg. p. 755. J. Ag. Sp. Alg. ii. 618. Modymenim sp., Grev. et Auct.) 

 1 . Calliblepharis ? temdfolia, Harv. ; fronde tenuissime membranacea rosea dichof omo-pinnata et e 

 margine foliifera, laciniis basi maxime attenuatis oblongo-lanceolatis nunc subciliato-dentatis, coccidiis . . . 

 tetrasporis (zonatim divisis) sparsis. 

 Hab. Chalky Bay, Lyall. 



Frond 6-8 inches long, 1 inch broad, with the aspect of C. ciliata, but very much thinner in substance, and 

 brighter in colour. Tetraspores scattered through all the lacuna?, zonate.— The genus of this plant cannot be cer- 

 tainly ascertained till the conceptacles shall have been discovered. It may possibly be a RhodopJiyllis. 



Tribe VI. GELLBLACEM. 

 Gen. LXI. GELIDIUM, Lamour. 



(J. Ag. Sp. Alg. ii. 466. Gelidium, Auct. excl. sp.) 



I. Gelidium corneum, Lamour., Harv. Phyc. Brit. t. 53. J. Ag. Sp. Alg. v. 2. p. 469. Kiitz. Sp. 

 Alg. p. 764. Eucus corneus, Huds., Turn. Hist. t. 257. E. Bot. t. 1970, etc. 



Hab. Hawke's Bay, Colenso. Banks' Peninsula, Lyall. (Generally diffused.) 



Besides an ordinary form, the var. clavatum, Grev. (caspilositm, J. Ag.), is sent by Mr. Colenso from Cape 

 Kidnapper, and another variety, growing on mussel-shells, from several localities, by Messrs. Colenso, Chapman, and 

 Davies. This latter variety, which at first we felt disposed to keep distinct, may be called subulifolium. It is 1-2 

 inches high, nearly or quite terete, as thick as hog's-bristle, and closely pinnate throughout ; the lowest pinnse short 

 and simple, the upper longer and compound. All the pinnules acute and thorn-like, mostly opposite. Colour dark, 

 lurid-purple.
