plentifully in the Tertiaries of France and of some parts of eastern Europe is recorded on 
good authority. 
Nubecularia inflata, n. sp. (PL I. figs. 5-8). 
Test consisting of a few, misshapen, inflated segments, irregularly combined ; aperture 
either single and simple, or, more usually, consisting of a number of rounded orifices 
variously placed. Diameter, ^th inch (0‘84 mm.), more or less. 
This is a protean species that only admits of description in very general terms. It 
supplies the links which connect the typical Nubecularia lucifuga with aberrant Milio- 
line forms like Miliolina labiosa, d’Orb., differing from the former in its comparatively 
modest size, the relatively small number of its segments, and their inflated contour, and 
from the latter in its extreme irregularity of growth, and the tendency exhibited by 
the individual chambers to form independent apertures. Amongst the littoral sands 
of our own coast wild-growing specimens of Miliolina subrotunda with some of the 
characters of Nubecularia are not uncommon, but in the absence of other distinctive 
marks their Milioline affinity is usually indicated by the aperture. 
I have notes of the occurrence of Nubecularia inflata in sand and mud from the 
following localities : — off Honolulu coral-reefs, Sandwich Islands, 40 fathoms ; off 
Tongatabu, 18 fathoms; off Tahiti, Society Islands, 420 fathoms; Nares Harbour, 
Admiralty Islands, 17 fathoms ; and Balfour Bay, Kerguelen Island, 20 to 50 fathoms; 
and at some of these points it is tolerably plentiful.

Nubecularia tibia is a porcellanous isomorph of Nodosaria. The test consists of a few 
ovate, pyriform, sub-cylindrical, or occasionally misshapen segments united end to end, 
and when regular bears considerable resemblance to some of the slender Dentalince. The 
aperture is a simple, round, terminal orifice, sometimes bordered by a thickened or 
everted lip. The shell is opalescent or opaque-white and imperforate. Owing, perhaps, 
to the thinness of the walls and the slenderness of the stoloniferous tubes, specimens are 
scarcely ever found with more than three segments, the maximum length being about 
3 \jth inch (0'84 mm.).
