12 COCCOPHYCES. 
Palmella Mooreana. Harv. Man. p. 178. 
Thallus irregularly globose, tuberculate, dark green, gelati- 
nous, firm. Cells nearly equal, pale green. 
Size: Cells:008 X -005 mm. 
Rabh. Alg. iii. p. 34. 
Coccochloris Mooreana, Hass. Alg. 316, t. 78, f. 1. 
In bogs and stagnant water. 
“The fronds are of an irregular globose form, about an inch in 
diameter, tuberculated, and inclining to become hollow in the centre 
when old, at which time it floats on the surface; the colour is dark- 
green and the substance firm, resembling that of an animal’s liver.”— 
Moore. 
We found this species floating freely in a pond in Sutton Park, Bir- 
mingham. In this condition it has just the appearance and texture of a 
Nostoc. Is it distinct from Aphanothece prasina ?

** Reddish or orange. 
Palmella miniata, var. equalis. Nég. Hinz. Alg. t. 4, D. 2. 
Thallus expanded, soft, amorphous, brick-red; cells nearly 
equal, tegument somewhat thick, colourless, hyaline, indistinctly 
striate; contents orange, sometimes greenish. 
Sizz. Cells :012-:014 mm. 
Rabh. Alg. iii. 34. Rabh. Exs. No. 1778. 
Sorospora grumosa, Hass. Alg. p. 310, t. 80, f£. 7.? 
On wet rocks, moist ground, &c. 
We are of opinion that this is the Sorospora grumosa of Hassall. The 
typical form of Palmella miniata has very minute cells, not exceeding 
-0035-°004 mm., but this variety, if it be not a distinct species, has cells 
nearly four times as large.

Palmella prodigiosa. Alont. Comptes Rend. 1852, 119. 
Thallus more or less expanded, blood: red, as age advances 
moist, orsometimes dripping; cells very minute, globose, 
crowded. 
Size. Cells :00075--001 mm. (Radh.).

Monas prodigiosa, Ehrb. Monat. Berl. 1848. 
Zoogalactina imetropha, Sette. Mem. Ven. 1824. 
On rice, bread, potatoes, &c. 
In the time of Ehrenberg this was considered a minute animal, and 
was included amongst Monads. The blood-red spots which it forms on 
bread, rice, potatoes, and other mealy substances, caused great alarm in 
more superstitious times. Until very recently opinions were by no 
means settled on this subject. The Rev. M. J. Berkeley held it to be a 
condition of fungoid life, and in his “ Introduction’’* he says, “ Pal- 
mella prodigivsa, from its peculiar habit, seems rather to indicate 
affinity with fungi. The rapidity with which it spreads over meat,
