“ Fronds minute, densely crowded, globose, green, composed
of pale green jelly, in which are numerous darker granules,
elliptic in var. a ; in var. fl globose, and accompanied
with smaller globose granules, collected more or less into
little rounded heaps, the longest of which are of the size of
the larger granules. After it has been dried, the jelly is
nearly colourless, and the granules are scattered, and all of
the same size.” — Rev. 3 i. J. Berkeley.
I t is evident from the preceding description tha t more than
one species is included under the name of Balmella Grevillei.
Note. I have since paid further attention to the subject of the division
of the mucous matrix into vesicles or cysts in Coccochloris, and I now
find that this structure is to be met with only in certain species of the
genus, and that it cannot be detected in any of the species figured in this
work. The species, therefore, with the frond thus divided, connect Cocco-
chlorisPiÛiIIcBmaiococcus, and scarcely differ from those of the latter genus.
It is still probable that the structure really does belong to all the Coccochlorides,
but that the extreme delicacy of the organization of some of
the species prevents its detection. Ramifying throughout the substance
of the fronds of all the species may be observed numerous slender
branched tubes, which may either be parasitic growth, or else form part
of the organization of the fronds ; and in the latter case they may be presumed
to be connected with respiration.
F a m . XYIII. PROTOCOCCEiE.
Char, Stratum indefinite, friable, formed by an aggregation
o f distinct globules, ivhich, not being immersed in gelatine,
and not enclosed by a common investing membrane, are
readily separable from each other on the application o f
moisture.

Char. “ Frond gelatinous, globose, at a later period entirely
constituted o f vesicles enclosing granules ; at length the
internal vesicles being absorbed, and the outer cellular
membrane defined, including granules imbedded in mucus.”
Derivation. The diminutive of florpvi, a bunch.
Ohs. “ Cl. Brehisson humanissimis literis observationes
suas communicavit, quibus innixus novum hoc genus pro-
posuit, has ipsas maxima pro parte et nos ipsi veritate
apprime respondentes invenimus. In hoc tamen nostra differt
sententia, quòd granula secundum Cl. Brehisson in alveolis
tantum periphericis sita, nobis contra in alveolis cum peri-
phericis turn interioribus initio nidulari videantur, sed alve-
ohs sine vesiculis illis interioribus serins resorptis, et periphericis
tantum iisdemque vacuis, membrana efformatur
glohulos jam evolutos et propagatione aptos muco obvolutos
includens. Nomen a Cl. Brehisson propositum, legihus
glossologlaj non omnino concisum, delere ansi non sumus.”

This genus resembles somewhat in structure the compound
pollen granules of many plants.
NoU. The Anacystis furfuracea Menegh., a production very different
from the Palmella furfuracea Berk., with which Meneghini supposed it
identical, and one coming near to Botridina, is a British Alga. I have
more than once met with it.
