Dr. W. H. Harvey’s Account of the Marine Botany of 
•56. Thamnoclonium n. sp. ; caule corneo crasso (pedali et ultra) echinulato in- 
ferne tereti superne alato ramose; ramis quoquoversum directis alatis phyllodia prolifere 
forentibus ; pliyllodiis furcatis v. dichotomis costatis basi cuneatis apice obtusis, segmentis 
lateralibus erectis plus minus incisis. Fremantle, cast ashore in July (320). I first received 
this truly noble species in a collection of Western Australian Alga3, made by Mr.Mylore, 
and presented to Ilerh. T. C. D. by my late lamented friend De. Charles Lemann, of Lon- 
don, to whose memory this plant is now consecrated. 
57- Dictymenia fraxinifolia. Fucus fraxinifolius. Turn. Eottnest, rare (241). I abandon the 
genera Epineuron and Spyrymenia as not being distinguishable from Dictymenia. 
.58. Dictymenia fimbriata, Grev. Garden Island, rare (110). 
59- Dictymenia tridens, Grev. Garden Island, Eottnest, and King George’s Sound (111). 
60. Dictymenia spiralis, Sond. Common everywhere (20). 
61. DKTYwmiA. pectinella, n. sp. ; fronde inferne valde costata superne sub-costata linear! distiche 
ramosa plana; ramis erecto-patentibus oppositis v. abortu alternis linearibus obtusis tenuis- 
sime costatis ciliato-fimbriatis ; ciliis oppositis argute pectinato-pinnatifidis involutis ; anthe- 
ridiis magnis ovalibus ad apices ciliarum fascioulatis. Garden Island, very rare (290). A 
very distinct and beautiful species. 
62. KiiTziNGiA ccma&MZato, Sond. Abundant everywhere. Often 2 or 3 feet in length (61). 
63. Kutzingia angusta, n. sp. ; fronde inferne costa cartilaginea percursa decomposite pinnata; 
ramis anguste-linearibus planis, superioribus tenuissime costatis v. ecostatis; ramulis oppo- 
sitis erecto-patentibus obtusis apice involutis. Eottnest, rare (242). A very much smaller, 
narrower, and thinner plant than K. canaliculata, of which it has the structure. 
64. Kutzingia serrata, n.sp. ; fronde basi cartilaginea denudata v. alato- marginata bi-tripinnati- 
fida et e costa primaria prolifera ; laciniis membranaceis planis tenuissime costatis, j uniori- 
bus, lacinulisque argute serratis. Eottnest, very rare (291). 
65. Australasica, Mont. King George’s Sound, common. Eare at Garden Island (31). 
66. EYTiPHLiEA eZata. (Rhodomela data, Sond.!) dendroidea (1-2 pedalis) ; caule tereti crassis- 
simo (2-3 lineas diametro) opaco ramoso; ramis decomposito-ramosissimis di-tri-chotomis v. 
vage divisis, minoribus ramulisque patentibus transversim striatis ; striis approximatis ; axillis 
latissimis ; ceramidiis ovatis pedicellatis ; stichidiis ad latera ramulorum fasciculatis ; sipho- 
nibus primariis 5-6 magnis, strato crasso cellularum minutarum ccrticatis. Cast ashore at 
Fremantle (304). A gigantic species, quite unlike any known to me. 
67- Trigenia Australis, Sond. Cast ashore in July, Fremantle (292). 
68. Acanthopiioea dendroides, n. sp. ; caule incrassato indiviso inferne nudo superne ramis alternis 
spiraliter evolutis vestito; ramis decompositis circumscriptione lanceolatis; ramulis spinosis, 
spinulis solitariis sparsis. Eottnest on the reefs, near low-rvater mark (224). Much the 
largest and most robust of the genus. 
69- Alsidium? spinulosum, sp.-, fronde tereti crassa dendroidea decomposite ramosissima ; ramis 
ramulisque erectis quoquoversum sistentibus; ramulis spimeformibus sparsis; ceramidiis 
ramulos terminantibus. Garden Island, Eottnest, and Cape Eiche (180). Primary tubes in 
the stem, 5, very large, and full of granular endochrome.
