Description Test morphology:The test is light in colour and approximately spherical to broadly oval in shape. One hundred and twenty four specimens had the following dimensions: length (measured along the axis passing through the aperture) 150–450 µm (mean 251 µm, standard deviation 54 µm), width 140–440 µm (mean 231 µm, standard deviation 53 µm), length/width ratio 0.88–1.37 (mean 1.09, standard deviation 0.08). The aperture is situated on a broad, low, moundlike projection with sloping sides and a slightly uneven outer edge. This ‘apertural collar’ is only visible when the test is orientated correctly. A thread of cytoplasm usually extends along the axis of the mound to the aperture. A corresponding invagination of the cytoplasm (‘peduncular sheath’) forms an inward extension of the aperture into the cytoplasm, although this feature is often indistinct and is not visible in all specimens. The test wall is transparent and colourless and appears as a thin but distinct line under a compound microscope. When placed in glycerol, specimens from sites44000 m water depth retain their shape, whereas those from the 2000 and 3000 m sites tend to shrink. [details]
