each cell ; cells alternate, rather distant, smooth, exactly cylindrical ; a little 
bent outwards, with a three-toothed rim ; ovicapsules strongly ribbed

Hab. Deep water. 
2. S. tenella, n. sp. Alder (p. 23, PI. II, figs. 3, 6). 
Minute, creeping, throwing up short unbranched or slightly branched 
stems, which are slender, zigzagged, and jointed above each cell ; cells 
alternate, rather distant, elongate, barrel-shaped, finely wrinkled across ;

1. L. negleda, n. sp. Alder, p. 33, PI. Ill, figs. 1, 2. 
Polypary minute; stem filiform, sub-flexuose, with two or three alternate 
simple branches, each bearing a cell ; the stem annulated, with from four 
to seven rings above t!ie origin of each branch, and sometimes slightly 
ringed below; the branches ringed throughout, cells narrow and deep, 
with alternate deep and shallow crenations, forming about eight biraucro- 
nated denticles round the margin. Polype with fifteen or sixteen slender 
tentacles. Height, ^ inch, 
Hab. Between tide-nwks, on under side of stones. 
2. L. acuminata, n. sp. Alder (p. 34, PI. Ill, figs. 5, 8). 
Polypary minute, scarcely branched, with a slender annulated stem ; the 
annulations strongest at the base, and becoming fainter or disappearing 
towards the cell. Cells thin, membranous, finely striated longitudinally, 
elongate pod-shaped, squared below, and tapering to a fine point above; 
margin slightly crenulated. Polype, when extended, two or three times as 
long as the cell; tentacles 20, nmricate, united by a web at the base. 
Height, inch.

2. Campamdaria. 
1. C. Johistoni^ u. sp. Alder (p. 36, PI. II, fig. 8). 
Stem creeping, plain ; pedicles long, with numerous close-set rings at the 
base, and more or less ringed at the top ; middle portion usually plain, 
sometimes ringed; cells deep and rather large, with ten to twelve strong 
denticles round the rim ; ovicapsules nearly sessile on the creeping stem, 
ovate-oblong, strongly plicated transversely and truncated at the top. 
Length, one and a half to two tenths of an inch. 
Hab. On seaweeds, zoophytes, shells, &c. Common. 
2. C. Hincksii, n. sp. Alder (p. 37, PI. II, fig. 9). 
Stem creeping, plain ; pedicles long, nearly smooth, with two or three 
slight spiral twists at the base and two or three spherical rings at the top, 
one of which is within the cup : cells rather long, with parallel sides, wrin- 
kled or lineated longitudinally; marginal denticles 10, of a squared or castel- 
lated form, a little indented at the top. .Height, about I inch.
