SUBSCRIPTION PROSPECTUS 
OF 
SPECIMENS OF AUSTRALIAN ALG A. 
DR. HARVEY of Trinity College, Dublin, being about to visit Australia, under the joint auspices of the 
University and of the Royal Dublin Society, for the purpose of exploring the natural history of the 
southern coasts of that continent, has made arrangements for extensively collecting Marine Alge, a 
portion of which (not required for the University Herbarium) will be offered for sale. 
The Australian shores are well known to be rich in varied and curious forms of Alge. Among the 
Olive Coloured Alge, many of the most remarkable Fucoids are either peculiar to those shores, or there 
assume their most remarkable development. The Fucaceous genera Sarcophycus, Myriodesma, Carpoglossum, 
Landsburgia, Hormosira, Notheia, Cystophora, Scaberia, Marginaria, Scytothalia, Seirococcus, and Carpophyllum 
are peculiar to New Holland and New Zealand. Among Laminariex several Eckloniev, and among Sporoch- 
noidee some remarkable Sporochni and Carpomitre occur. Of the other Orders of the olive series there are 
also several beautiful forms, though less characteristically peculiar than those just named. 
Among Rhodosperms, the remarkable forms are much too many to enumerate. Here occur the 
most beautiful of the net-work Alge, as Claudea, Thureia, Hanowia, Halophlegma, &c. The genera 
Amansia, Pollexfenia, Dictymenia, Epineuron, Lenormandia, Jeannerettia, Polyphacum, Polyzonia are among 
the most interesting Rhodomeliew; while numerous beautiful species of Dasya and Polysiphonia complete 
that Order. Among Laurenciacee, the exquisite Delisiv, with Asparagopsis, Ptilonia, Champia, and numerous 
Laurencie, are found. Of Sphewrococcoider, many beautiful Delesserie and Nitophylla, Hemineura, Thysano- 
cladia, Dicranema, Sarcodia, Melanthalia, Eucheuma, Phacelocarpus, §c. Several fine Wrangelie ; Gelidium, 
Pterocladia ; Apophlea, Curdiea ; many superb Plocamia ; Stenogramma, Rhodophyllis, Areschougia, Ehab- 
donia ; several beautiful Callithamnia, Ceramia, Griffithsie, and Ptilote ; Ballia, Dasyphila, Ptilocladia, &c., 
are included in the extensive catalogue. 
Among Chlorosperms, numerous and very curious Caulerpe, and several genera of Siphonec, with the 
usual proportion of Confervacee, may be noticed. 
As yet, the Australian Coasts have been very imperfectly explored :—naturalists and collectors who 
have hitherto visited Australia having chiefly attended to other departments, and but cursorily collected 
and often carelessly preserved the Marine Alge. While Dr. Harvey’s duties will comprise the collection 
of all marine productions, his attention will be more particularly fixed on the Alege, among which, there- 
fore, it is hoped he will reap an abundant harvest of new and beautiful forms, particularly among the 
more delicate and perishable kinds. The specimens will be all collected and carefully preserved either by
