Mr. A. W. Waters on the 
lated, though the Falkland-]stands L. personata has a large 
avicularium. The characters of the ovicells of personata are 
not quite sufficiently given in the { Catalogue of the Marine 
Polyzoa.’ 
Operculum (30*) - 14 millim. wide, *076 long. 
Loc. Widely distributed ; occurring in the northern seas 
( Smitt ) and in South America and New Zealand. It has 
been found fossil in the English Crag and in the Pliocene of 
Castrocaro (Italy). 
8 . Lepralia himucronata , Moll, var. granifera . 
(PI. VIII. figs. 2, 3.) 
Lepralia granifera, Johnst. (part.) in Landsborough, History of Brit. 
Zoophytes, p. 309. 
Zooecia ovate, front punctured all over with large stelliform 
pores, large central round or lunate pore on umbo ; aperture 
rounded above, straight below, margin raised on both sides. 
Ovicells globose, smooth, with occasional small perforations. 
Operculum thicker at the two sides, correspondiug to the 
raised margins. 
This species is closely related to L. Malusii , but is much 
smaller (as will be seen from fig. 3, on the same scale as most 
of the species drawn), and has an itmbo looking forward, so 
that often the semilunar or circular pore cannot be seen. It 
is difficult to decide if this should be considered a variety of 
Moll’s L. himucronata, as he does not figure any umbo; but 
sometimes cells are found without, or it might be overlooked. 
It is also very closely related to Lepralia granifera , Busk, 
but does not, from an examination of the Museum specimen, 
appear to be exactly the same, though a variety, but is evi¬ 
dently the same as the umbonated variety figured by Lands¬ 
borough. 
One of our best authorities does not agree in thinking this 
the same as himucronata of Moll; and if this is thought to be 
the case it might be called granifera , var. occidua , as the pore 
often cannot be seen. There are two small teeth in the lower 
edge of the pore. 
Operculum (31*) : width 0T 16 millim., width of proximal 
edge 0’08, length 0084. 
Common, covering seaweed from depths of a few fathoms. 
9. Lepralia violacea, Johnst. 
Porina violacea, Smitt, Floridan Brvozoa, Kong). Svenska Vet. Akad. 
Handl. 1873, vol. ii. pt. 2, p. 30. 
I have only met with this two or three times at Naples, 
and then from depths of about 40 fathoms. Heller gives the 
depth as 20-55 fath., and Smitt as 35 fath.
