ALGE OF MALDIVE AND LACCADIVE ISLANDS. 475 
List of Marine Algew collected at the Maldive and Laccadive 
Islands by J. S. Garpiner, Esq., M.A. By Erner S. 
Barton (Mrs. Antony Gepp). (Communicated by A. Grpp, 
M.A., F.L.S.)

THERE appears to be no record of the marine algw of these 
islands, neither are there any specimens from them in the British 
Museum Herbarium. This list includes one new species, but all 
the rest recorded here, with two exceptions, are already known 
from the Indian Ocean. One of the plants is especially inter- 
esting as enabling a doubtful species to be elucidated, and another 
provides material for the drawing-up of a diagnosis of a plant 
hitherto undescribed and known only in Herbaria. All the 
Minikoi specimens were collected on July 26th, 1899. 
In thanking Mr. J. Stanley Gardiner for allowing me to work 
out this collection, I would draw attention to his interesting 
notes on the habitats of the species, incorporated below almost 
verbatim. As a general observation, he states that ‘“‘ Alge on 
tropical coral-reefs in oceanic areas never form more than low 
growths. Most of the reef-surface is bare, or towards the edge 
covered with nullipores (Lithothamnion). However, the latter 
area, where the waves break, is richer than the reef-flat, but too 
dangerous for proper collecting.” Ordinarily, alge are not 
found on shoals in the lagoon, the whole being covered with 
growing corals.
