74 PROCEEDINGS OF SOCIETIES, 
worthy of notice, and these I shall mention as I come to them in 
their natural order. 
In the first place I have to show specimens of three species of 
Nullipore-—-namely, IV. polymorpha, N. calcarea, and N. fascieu- 
lata; also NV. ealcarea, var. depressa. 
The list of Foraminifera is an extensive one, especially con- 
sidering that all my specimens are from shore-sand and from one 
locality. This sand is from Dogs Bay, Roundstone, and consists 
of many kinds of small shells of Mollusca, among which Risso 
and Lacune are more noticeable at first sight, fragments of 
Lepraliz and other Zoophytes, spines of Amphidotus, and sponge- 
spicula, while the finer parts are made up entirely of Foraminifera. 
Of these I have found fifty-eight species and named varieties, and 
also six very distinct forms which are not mentioned in Professor 
Williamson’s ‘Monograph on Recent British Foraminifera,’ 
Specimens of these, and of all the other forms contained in the 
list, are mounted for inpseetion. 
In the course of my frequent examinations of these objects I 
have made a few observations on several of them, which may per- 
haps be interesting. ies. 
ft find Orbulina wniversa common in the Dogs Bay sand; that 
is, [ have picked out some hundreds of specimens. They vary 
greatly in size, the largest being four or five times the diameter of 
the smallest. They have the surface frosted with larger and 
smaller tubercles, arranged with a certain kind of regularity ; but, 
though thus rough externally, the texture of the shell does not 
appear to be arenaceous, as stated by Professor Williamson—at 
least, if by that term is meant that it is formed of agglutinated 
grains of sand, as is the case with some other species. When 
examined with a high power and transmitted light, the larger and 
smaller tubercles show black from their density, and the spaces 
between them are partly occupied by objects lke very transparent 
thin plates, of a uniform size and an imperfectly squared figure ; 
the impression these convey being that they have been produced 
by a kind of crystallization of the material of the shell at the time 
of its original formation. I conclude that the colourless condition 
of my specimens depends on the perfect manner in which all 
animal matter has disappeared, and I think for an examination of 
the mere structure of the outer case this must be an advantage, 
Tt may be interesting to note that among the specimens are a few 
with one or more protuberances of parts of their surface, destroy- 
ing the regular spherical figure, and indicating an incipient 
budding before the shell hardened; there is also one large and 
very handsome double specimen. 
Besides the Orbulinas, I have an example of another kind of 
spherical object, which for convenience I will mention here, though 
I do not suppose it to belong to the Foraminifera at all. It looks 
like a sphere of the most transparent glass, and is without colour 
or markings of any kind. 
I have found all the forms of Lagena, excepting ZL. vulgaris
