THE VOYAGE OF H.M.S. CHALLENGER. 
North Atlantic, from the coast of Norway and the Faroe Channel to the west of Ireland, 
the Azores, the Danish West Indies, the Cape de Verde Islands, and southwards to the 
equator. In the South Atlantic it has been collected at four Stations, between 
Pernambuco and the Falkland Islands ; it occurs at two Stations between the Cape 
of Good Hope and Kerguelen Island, and at seven in the South Pacific. It is a 
somewhat curious fact that, though it is found in the South Pacific to within about 
two degrees of the equator (Station 218), not a single specimen has been met with 
in any of the North Pacific dredgings. Parker and Jones record the occurrence of 
the species at eight localities in the Mediterranean, at depths varying from 90 to 1700 
fathoms. It is not known in the fossil condition.

Test adherent, monothalamous; circular in outline, convex or subconical; presenting 
no visible aperture; walls finely arenaceous, smooth externally ; colour dirty-white to 
reddish-brown. Diameter, -^th to x§th inch (0'5 to D4 mm.). 
There is little to be said about this very simple organism. Its contour is that of a 
low bell-tent, and it has no conspicuous orifice, the sarcode presumably finding its outlet 
between the rim of the test and the object upon which it is parasitic. 
The specimen originally described was found amongst other fossil microzoa from the 
Crag of Sutton ; and no other locality was known for the species until it was dredged in 
the living state., in 1874, by Dr. G. S. Brady and Mr. Robertson, at two points on the coast 
of Durham, namely : — seven miles off Marsden, 33 fathoms ; and five miles off Red Cliff, 
25 to 30 fathoms. Apart from doubtful specimens, these particulars comprise what is 
known of its distribution.
