Bryozoa of the Bay of Naples. 
Lepralia Kirchenpaueri, Heller, Bry. Adriat. Meeres, p. 105, pi. ii. 
fig. 11; Manzoni, Supp. Fauna dei Bry. Medit. cont. 1, p. 8, pi. iii. 
fig. 3. 
Lepralia cupulata, Manz. Bry. foss. Ital. cont. 3, p. 13, tab. iv. fig. 21; 
Waters, Bry. from PI. of Bruecoli, Manch. Geol. Soc. vol. xiv. pt. 21, 
p. 473, fig. 6. 
All my specimens are upon a small Trochus , and show con¬ 
siderable variation, so that on one piece some cells have the 
two large bosses, while others are without; and from these 
variations I think we are justified in reducing the syno- 
nymy. 
Operculum (20*) suboblong, T04 millim. in length, ’06 
millim. wide, except at the base, where it is *08 millim. 
Loc. Miocene, Pliocene, living. Add Pliocene, Castellar- 
quato and Bruecoli. 
32. Lepralia fissa, Busk. (PI. XI. fig. 6.) 
Lepralia Jissa, Busk, Quart. Journ. Micr. Sc. vol. iv. p. 308, pi. ix. 
figs. 8, 9, 10. 
The peristome is much raised, with long spines, but does 
not show the dentation mentioned by Busk; the walls are 
thin, granular, somewhat hyaline ; and large avicularia occupy 
the space of a zooecium. 
The small fragment from Naples very much resembles L. 
Lyallii , as figured by Busk, although none of the cells have 
a vibraculum. As the British-Museum specimen is, unfor¬ 
tunately, not in its place, I have been unable to make a com¬ 
parison. 
33. Eschara foliacea, stadium Hemeschara. 
(PI. XI. figs. 4, 5.) 
This is another case of finding cells similar in the Eschara 
and Hemeschara or Lepralia forms. 
Figs. 4 and 5 are taken from different specimens. 
The avicularia are very small, and are situated in the primary 
mouth. The globular ovicells have two openings just above 
the aperture ; sometimes a raised peristome joins the ovicells ; 
but as there are but few ovicells on the pieces in my posses¬ 
sion, it is impossible to say how general this may be. 
The ovicells of Eschara foliacea do not seem to have been 
described as yet. 
Operculum (24*) somewhat sellate; width 0T8 millim.; 
muscular attachment central on the border of the operculum. 
(The scale and most of the figures are magnified 25 times.)
