66 ZOOPHYTOLOGY. 
A very distinct species, characterised at once by the minute 
sessile avicularium, with an acute triangular avicularium 
immediately below the aperture. The presence of this organ 
and the smooth peristome distinguish it sufficiently from 
S. Macandrei, B., the only other species with which it could 
possibly be confounded. Savigny’s figure is very correct to 
nature, so that no doubt whatever can be entertained of the 
identity between the Madeiran and Levantine (?) forms. 
3. Gen. Lepralia, Johust. 
1. L. Pouilletii, Aud. Pl. XXTI, fig. 6. 
Cells oval, front marked with radiating lines of minute puncta. Mouth 
raised, and advanced in front, with five or six marginal spines above. 
Hab. Madeira, Johnson; Mediterranean (?), Savigny. 
Esch. Pouilletti, Savigny, ‘ Egypt,’ pl. xii, figs. 1—5; Audouin, 
* Expl.’ p. 240. 
This is another of Savigny’s species, with respect to whose 
identification little or no doubt can be entertained. It is 
readily distinguished from L. radiata, Moll., by the absence of 
the large avicularia and the uniformity of the front of the 
cell. 
2. L. discoidea, nu. sp. Pl. XXII, figs. 7, 8. 
Cells disposed in regular lines radiating from a centre, closely aduate, 
immersed. Mouth with a raised margin, keyhole shaped. Surface pitted. 
Hab. Madeira, Johnson. 
4. Gen. Eschara, Linn. 
l. #. distoma. Pl. XXII, figs. 10—12. 
Polyzoary ligulate, subterete, branches narrow. Upper part of cell much 
advanced; mouth arcuate, expanded below. Beneath the mouth, in the 
centre, an acute elongated avicularium, and below that, in the front of the 
cell, a depressed space, perforated at the bottom with two rows of minute 
pores. Surface minutely granular or wavy. 
Hab. Madeira, Johnson. 
This is the species described in last part of Zoophytology, 
from an imperfect fragment, as L. distoma, B. It is, however, 
as there suggested, clearly an Eschara. 
5. Gen. Cupularia, Lamx. 
l. €. Lowei, Gray (sp.) 
2. C. Canariensis, n. sp. Pl. XXIII, figs. 6—9. 
Polyzoary depressed, circular, about 0:5” in diameter. Front of cell sub- 
rhomboidal, expanded below the middle, aperture oval. Lamina granular, 
with an entire margin. Back divided into quadrangular portions, in each of 
which are from two to four perforations. 
Hab. Madeira, Johnson; Canaries, McAndrew. 
A distinct and well-marked form. Numerous specimens
