Catalogue of Marine Algce, collected by Dr. W. H. Harvey in Western Aus- 

 tralia, from January to August, 1854 ; icith 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 mnning 

 Catalogue, Isept by Dr. H., as the Collection proceeds. 



Series I.— MELANOSPERME^. 



Order I.— FUCACE^. 



S.utGASsnM, ■) Several species of these genera have been collected and packed away without 

 Cystophora, / examination, and are not now accessible. 



1. ToRBiNARiA vulgaris, J. Ag. Fragments on the beach, Fremantle (288). 



2. ScTTOTHALiA dorycarpa, Grev. Rocks below low-water mark, common. King George's 



Sound, and Rottnest (300). 



3. ScYTOTHALiA dorycarpa jS. 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. ScABERL\ Agardhii, Grey. Very common everywhere, in 2-3 fathoms (83). 



5. Ctstophtllum murkatum, J. Ag. Common in Princess Royal Harbour, King George's 



Sound; and in the Swan River, from Perth to Fremantle (73). 



6. Ctstoseiea ^jro?(/c;-a, 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. CARPOGLOSsnM quercifolium, Kiitz. Rottnest, on the reefs ( ). 



9. Carpoglossdm angustifoUuvi, 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. Myriodesma latifolium, u. 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 J/, serridatum, but the segments are an inch broad, densely dotted with 

 innumerable scaphidia. It is quite different from M. quercifolium, Bory. 



12. NoTHEiA anomala. Bail, and Harv. Harv. in Hook. Fl. Nov. Zcl. cum icone. Parasitical on 



Hormosira in Princess Royal Harbour. 



Order H SPOROCHNACEjE. 



13. Sporochncs comosus, Ag. (?) King George's Sound and Fremantle, two or three feet long, 



and much stouter and more rigid than S. pedunculatus (13).
