or very faintly granular; no calcareous expansion; one or two very long, 
slender, hair-like marginal spines on either side of the upper part of the 
cell. Ovicell small, immersed ? 
Hab. Madeira, Johnson (on shell). 
The only form with which this can be confounded is M. 
Flemingii, Busk (‘ B. M. Cat.,’ p. 58, pl. Ixi, fig. 2, and_ pl. 
Ixxxiv, figs. 4—6), but from which it is clearly distinguished 
by the characters above given, and especially by the absence 
of any calcareous expansion, and the extraordinary length and 
slenderness of the hair-like spines. 
3. M. , i. sp. 
A figure and description of this species will be given here- 
after. 
5. Gen. Lepralia, Johnson. 
l. LZ. distoma,n. sp. Pl. XVIII, fig. 1. 
Cells pyriform, attenuated below. Mouth semi-orbicular, with a straight 
lower lip, separated only by a narrow bar from an avicularium, the opening 
of which is nearly as large as the mouth, the two openings being encircled 
by a raised border common to both. A depressed space on the front of the 
cell, the bottom of which is perforated with six or seven pores. A row of 
distant pores around the border of the cell. 
Hab. Madeira (on fucus ?), Johnson. 
From the form of the small fragments in our possession 
they would seem to be growing all round the slender 
branches of a fucus, but the species may turn out to belong 
to the hgulate Eschare. 
2. L. vulgaris, Moll. Pl. XVIII, fig. 3. 
Cells oval, convex ; surface subgranular. Mouth semi-orbicular, lower lip 
straight, with a median notch. Three or four superior marginal spines. 
Ovicell small rounded. A slender vibraculum on each side of the cell about 
the middle. 
Hab. Madeira, Johnson ; Mediterranean, Moll. 
Eschara vulgaris, Moll., ‘ Eschara,’ p. 55, pl. iii, fig. 10. 
Escharina vulgaris, Lamarck, ‘H.n. d.s. V.,’ 2d ed., t. ii, p. 281 (ex. 
syn. L. Dutertret). 
Cellepora vulgaris, Lamx., ‘ Hist.,’ p. 94. 
From Moll’s account, and the name he has given to this 
species, it would seem to be very common in the Mediterra- 
nean. 
3. L. P n. sp.

4. L. , a. sp.? resembling Z. ventricosa. 
This species will be afterwards described and figured. 
5. L. sceletos, n. sp. 
This species will be afterwards described and figured.
