Bryozoa of the Bay of Naples. 
(fig. 3). In most large colonies two or three such avicularia 
are usually found. 
As I am not aware that this has been pointed out before, it 
may have struck some as strange that I should have allied a 
form figured* as var. leontiniensis with auriculata-, but I 
think the specimens fully justify the determination; and, in 
fact, I have since found that auriculata grows frequently in the 
Hemeschara stadium, and often with many layers of cells one 
above another; so that it is very doubtful if the Bruccoli 
specimen is different from recent ones from Naples. 
In Eschara foliacea , which has an avicularium somewhat 
similar to that of auriculata , horizontal avicularia sometimes 
occur; and the same variations are known in E. pertusa , 
M.-Edw., and in E. macrochila , liss. 
Widest part of operculum (13*) 0*1 millim., proximal edge 
0084, length 0*08. 
Loc. Pliocene, Bruccoli. Living : Britain, Finland, Spitz- 
bergen, Greenland. 
6 . Lepralia ciliata, Pall. 
Escharina armata, D’Orb. Voyage dans l’Amdrique, vol, v. p. 15, vol. 
ix. pi. 4. figs. 1-4. 
Width of operculum 0* 121 millim., length 0*073. 
Loc. Miocene and Pliocene (see Bry. from Brucc.). Living: 
Arctic seas, Britain, Mediterranean, Florida, New Zealand 
(Hutton), South Africa, var.? ( J. Boyd's coll.), Novaja Semlia 
( Smitt , 1878), Falkland Islands ( D'Orb .). 
7. Lepralia Malusii , And. 
Cellepora Malusii, Savignv, Egypte, pi. 8. fig. 8, 
Manzoni (“ Supplemento alia Fauna dei Bry. Medit.,” Sitzb. 
Akad. Wissensch. Wien, lxiii., 1871, Taf. ii. fig. 2) gives a 
very good figure of this most beautiful Lepralia , but did not 
find in his specimens the stelliform pores; whereas in all I 
examined from Naples they are most distinct, and correspond 
exactly with the British specimens, as well as with one from 
Tierra del Fuego in the British Museum. 
Heller mentions a variety (Taf. ii. fig. 3); but it appears as 
if some slip had been made about it, as there does not seem 
any thing in common. 
The ovicells of Lepralia per sonata , Busk, are similar, as 
also the lunar pore ; and we must look upon these two as re-
