48 ON THE GENERA ANADYOMENE AND MICRODICTYON. 
and a series of specimens from Florida collected by Professor Harvey, 
which he most kindly presented to me. 
If I could regard these Mediterranean specimens as fair types of the 
plant usually found there, I should decide that it was distinct from 
those from Florida. These small fronds only contain a very few large 
cells, very different in this respect from the Florida specimens, but, on 
the other hand, the specimen figured by Lamouroux, found in the 
* Mousse de Corse," more nearly resembles those from Florida, and 
one can hardly believe that the Corsican Aly@ he examined could have 
come from the coast of America. 
2. “ A. plicata; frond plicate; veins subtrichotomous."—C. A. 
Agardh, Sp. Alg. i. 400; Kützing, Sp. Alg. 511. 
Has. Island of Rawak, Gaudichaud. 
* Differt a precedente (4. stellata) statura minore, fronde maxime 
plicata, venis paucioribus trichotomis, cum in illa frons tota venis occu- 
pata est, hec magis continua venis quibusdam membranam percurren- 
tibus; habitus omnino Collematis.”—C. A. Agardh, Species Algarum, 
i. 400, 1823. 
3. A. Cutlerie ; frond membranaceous ; the cells oblong, nearly as 
wide at the base, with several diverging cells at the upper part, each 
bearing a similar series of diverging cells at the apex; the frond be- 
tween the main cells filled up with one or two series of large cells at 
right angles with their margin. 
Has. Bermuda. 
Deseribed from a fine specimen received by Miss Cutler from Ber- 
muda, and presented by that lady to me with the rest of her exotic 
Alge. I have divided the specimen between the British Museum, Dr. 
Harvey, and my own collection. 
4. A. Wrightii ; frond imbricated, coriaceous; joints linear-elon- 
gate, several times longer than broad, with a radiating group of cylin- 
drical branches at the tip, two to four of which are longer than the 
rest and proliferous at the tip; the branchlets near the margin five or 
six, shorter, radiating, of nearly equal length ; the interspaces between 
the branches wide, and filled up with small subequal cells.—A. 
Wrightii, Harvey, mss. 
Has. Loochoo Islands, C. Wright, King's and Roners's loring 
Expedition, 1853 and 1856. = 4 qui quain
