The next of our stations at which I was able to make any con- 
siderable collections of algae was at Guantanamo Bay, Cuba, on 
he U. S. Naval Station’s reservation, where I began work on 
March 17. The inner portions of this large bay are or have 
been fringed with red melas sacle eis and the 
adjacent bottom consists mostly of “mangrove mud,” on whi 
a marine plants are not aes diversnca, or an but 
ward the mouth of the harbor and-on the outer coast, which 
: chiefly rock-bound, there is much of interest. Several of the 
plants collected here were entirely new to me and I would not 
venture an opinion as to their affinities until there has been an 
opportunity for a more critical study of their structure. Amon 
the more readily recognizable plants of peculiar interest were 
that which I described in 1905 from Cape Florida as Sarcomenta 
Jilamentosa and which, so far as I know, had not been collected 
elsewhere, and also Neomeris mucosa, a well-marked species 
I had recently proposed as new on the basis of material 
ete last year in the Caicos Islands and the southern 
Bahamas. 
In Key West, Florida, on April 7, I enjoyed an Sepa 
of making a brief comparison of the spring marine flora, a 
hibited by the seaweeds washed ashore, with the autumn ae of 
the same places, as recalled from previous experiences in Key 
West in October and November, 1902. Most of the species ob- 
served were common to these two periods, but my general im- 
pression is that the marine flora of the autumn months is consid- 
erably more varied and abundant. In the two days that we spent 
on and about Boot Key I was able to secure several plants of in- 
terest, including good specimens of the large and handsome Caw- 
lerpa Ashineadii, which previously I had found only in the form 
of fragments washed ashore at Key West. Caxderpa lanuginosa 
had ever seen it elsewhere and Caulerpa prolifera was not uncom- 
mon, I was able also to obtain a good series of luxuriant speci- 
mens of the recently published Halimeda simulans, here, as
