On a pebble, intermingled with Meomeris annulata, was the 
minute and dainty Acetabulum Ge lael which is probably 
on ghout the West Indian region, even though it 
ordinarily remains undetected owing to its small dimensions. 
One of the most interesting finds at Port Antonio was what 
appears to bea plant of the species originally described from 
Guadeloupe in 1854 by J. Agardh as Bryopsis Duchassaingii 
and redescribed in 1860 by ie as representing a new 
genus, Tia with Antillarum as its specific name. So far 
as the writer is aware, this plant has hitherto been known only 
from the Guadeloupe collections of fifty or more years ago. It 
was found growing attached to a stone at about the low-water 
line. The same thing was found in greater abundance a few 
days later at Port Morant on the eastern coast of the island, 
where I arrived on March 3, stopping at the Peak View Hotel 
t Bowden, where you and Mrs. Britton and Mr. Harris had 
sey esauie ed headquarters. In and about Port Morant 
a great variety of conditions as regards the nature and 
degree of exposure of the shore-line, from the protected waters 
of the harbor to the outside rocks and beaches, where the easterly 
trade-winds keep the waters in almost constant agitation. Ac- 
cordingly, the marine plants of the Port Morant region are varied 
and abundant. On the wooden piers of the wharves of the east- 
ern side of the harbor, six species of Caulerpa thrive luxuriantly. 
On the stones and pebbles near by grow the interesting ‘“ 771- 
chosolen”’ mentioned above and the almost equally rare Siphono- 
cladus tropicus. In shallow water on rocks nearer the mouth of 
the harbor grows the exquisitely formed Dictyurus occidentalis, a 
species which I had previously found only in the form of frag- 
ments washed on the shore. Creeping on exposed surge-swept 
rocks outside the harbor, a handsome Asparagopsis was found. 
An interesting day was spent at Holland Bay and Morant Point, 
extreme eastern end of the island of Jamaica. Here good 
specimens of Gracilaria cervicornis were being washed ashore, 
and Petrosiphon, an encrusting Valoniaceous plant which I ven-
