In tbis species wben tbe adherent chamber is of large size tbe 
tubular portion is short, but when it is small the tubular portion 
is usually extended to a considerable length. A somewhat similar 
mode of growth appears largely to prevail among the Poramin- 
ifera generally, as individuals with large primordial chambers 
have, as a rule, fewer segments than those in which it happens 
to be small. At 750 fathoms the species was met with in con- 
siderable numbers, the tubular portion being often very long, and 
having attached to it minute rounded fragments of quartz, of very 
uniform size, arranged alternately in a pretty chain-like pattern.
