Dr. W. H. Harvey’s Account of the Marine Botany of 
Catalogue of Marine Algae, collected hy Dr. W. H. Harvey in Western Aus- 
tralia, from January to August, 1854 ; with short Descriptions of the New 
Genera and Species. 
Note.— The Numbers between parentheses ( ) in this List are those under which the Species stand in a rir'clug 
Catalogue, kept by Dr. H., as the Collection proceeds. 
Series I.— MELANOSPERMEiE. 
Order I. — FUCACEAl. 
Sargassum, n Several species of these genera have been collected and packed away without 
Cystophora, / examination, and are not now accessible. 
1. TaEBiNAEiA vulgaris, J. Ag. Fragments on the beach, Fremantle (288). 
2. ScYTOTHALiA dorycarpa, Grev. Rooks below low-water mark, common. King George’s 
Sound, and Eottnest (300). 
3. SCYTOTHALIA dorycarpa j3. xiphocarpa; S. xiphocarpa, J. Ag. Thrown up from deep water 
at King George’s Sound and Cape Riche. I consider that the characters which distinguish 
this plant from the preceding depend on depth of water, and exposure to currents (301). 
4. ScABERiA Agardhii, Grev. Very common every where, in 2-3 fathoms (83). 
5. Cystophyllum muricatum, J. Ag. Common in Princess Royal Flarbour, King George’s 
Sound; and in the Swan River, from Perth to Fremantle (73), 
6. Cystoseira prolifera, J. Ag. A single specimen on the beach, Fremantle, after a gale (287). 
7- Hormosira Labillardieri, Bory. Common near high-water mark, and at half- tide, in Princess 
Royal Harbour, King George’s Sound. Rare at Cape Riche. Not seen elsewhere (76). 
8. Carpoglossum quercifolium, Kutz. Rottnest, on the reefs ( ). 
9. Carpoglossum angustifolium, Sond. Cast ashore at Cape Riche and Fremantle ( ). 
10. Myriodesma serrulatum, Dne. A few specimens picked up at Cape Riche and Fremantle, after 
storms (159). 
11. Myrtodesma latifolium, n. sp. ; on the beach at Fremantle (278). My specimens not being at 
hand, I cannot at present further characterize this new species than by saying that it has 
the ramification of M. serrulatum, but the segments are an inch broad, densely dotted with 
innumerable scaphidia. It is quite different from M. quercifolium, Bory. 
12. Notiieia anomala. Bail, and Harv. Harv. in Hook. FI. Nov. Zel. cum icone. Parasitical on 
Hormosira in Princess Royal Harbour. 
Order II SPOROCHNACEiE. 
13. Spoeochnus comosus, Ag. (?) King George’s Sound and Fremantle, two or three feet long, 
and much stouter and more rigid than S. pedunculatus (13).
