8 TRANSACTIONS OF THE [ Sess. LXxmI. 
As most of my time was spent in the interior of the island, 
I unfortunately had little opportunity of visiting the sea- 
shore. However, once or twice when passing along or near 
the coast I made an effort to get a few specimens, especially 
such as were not too large to carry about with me. The 
result was only a collection of about twenty specimens, but 
of these, as far as I have been able to discover, none have 
hitherto been recorded from the island of Dominica. This 
encouraging fact has made me think it may be worth while 
recording this small collection. Mr. E. M. Holmes has been 
good enough to name the specimens, and he says several of 
them are interesting and rare. I am also indebted to him 
for the observations appearing in connection with several of 
the sea-weeds noted, under which appear his initials. 
The Sargassum weeds will help to illustrate the distribu- 
tion of that interesting family of sea-weeds, especially those 
in fructification. I have no doubt that another visit to the 
island would enable me greatly to add to my collection, as 
most of the likely places were too far out of the way for me 
to reach, and I had so much other work on hand. 
The notes upon the distribution of the sea-weeds referred 
to in this list are mostly taken from the “Catalogue of the 
Marine Algz of the West Indian Region,” by George Murray, 
Esq., F.L.S., which appeared in the “ Journal of Botany ” for 
1888, pp. 193, 237, 303, 331, 358, and for 1889, pp. 237, 
257, 298; also some of my information I owe to De Toni, 
“ Sylloge Algarum.” 
To Mr. E. M. Holmes, F.L.S., and the authors above 
mentioned, I desire to tender my best thanks.
