the Mediterranean. A peculiar flexible Rhizopod, with a chitinous cortex, 
studded with Globigerina, and enclosing an olive-green sarcode, is recorded 
from off* the S.W. coast of Ireland in 2436 fathoms water. In the Cold 
Area” between Scotland and the Faeroes the Globigerina-mud is entirely 
wanting j and, with the exception of certain arenaceous typos, Foraminifera 
are not here conspicuous either for number or variety. One of these arena- 
ceous types forms Dr. Carpenter’s new genus Botellina {ih. p. 444). Tubes 
f to 1 inch long, like straight Lituolce externally j but the cavity continuous 
throughout, though traversed in every part of its length by irregular processes, 
built up partly of sand-grains, partly of sponge-spicules. Sarcodic body 
filling the whole of the cavity, which communicates with the external me- 
dium by irregular apertures at one end of the tube (free ?), the other extremity 
(attached ?) being uniformly open in the specimens obtained. Dredged in 
440 fathoms at a station intermediate between the warm and cold areas. 
The same authors (p. 478) support the view that the Protozoic portion of 
the Deep-sea Fauna is nourished by direct absorption of organic matter 
diffused through the whole mass of the oceanic water. 
Squamulina scopula, sp. nov.. Carter (Ann. N. H. (4) v. p. 309), Budleigh- 
Salterton, Devon j S. vartans, sp. nov.. Carter (ib. p. 321), same locality. 
Both these species are arenaceous, and have, besides siliceous grains, sponge- 
spicules entering into the formation of their test. S. scopulUf bearing on 
its discoidal base a column, brush-like with attached sponge-spicules, is 
the same as Ilaliphysema tumanowiczii of Bowerbank, described by that 
author as the smallest British sponge. 11. ramulosUf Bbk., Carter regards as 
probably a branched variety of the same rhizopod {ib. June 1870, p. 390). 
The same author’s subsequent observations {ib. Oct. 1870, pp. 346, 347) con- 
fiim his views both that Squamulina scopula is a foraminiferous animal, and 
that Ilaliphysema ramulosa^ Bblf., is a variety of it. After cutting off the 
branched head of the latter variety he observed the protrusion and retraction 
of branching and anastomosing pseudopodia, with circulation of granules. 
Carter describes the sponge-spicules found in connexion with the test of 
Polytrema {ib. pp. 891, 392). Allman states that, although he has seen 
siliceous spicules resembling those of sponges in the interior of the chambers 
of Polytrema miniacea, in many specimens he could find no trace of them 
(Ann. N. PI. (4) v. p. 373). 
Messrs. Brady, Parker, and Jones, in their monogTaph of the genus 
Polymorphina, enumerate and describe forty-one recent and fossil species, 
including three belonging to the subgenus Dimorphina. Read in the light 
of the older definitions the whole of these must really be regarded as a single 
species,'’ as from end to end of the series there is no single break. No less 
than twenty-four generic synonyms are quoted (Trans. Linn. Soc. xxvii. 
pp. 197-253).

Brackish-water Foraminifera. In Mr. H. B. Brady’s Analysis ” (Ann. 
N. H. (4) vi. pp. 273-309) a table is given showing the results of gatherings 
from thirty-two brackish localities, all British, save one from the Scheldt 
near Antwerp. An additional column collates the results of Messrs. Parker 
and Jones’s fen-clay investigations. Of forty-four reputed genera found 
in the British seas only twelve are entirely absent, viz. Ilauerina, Sac-
