89. Not having had the good fortune to obtain specimens
in which the animal body has been preserved, I cannot
speak as confidently on the subject of its conformation,
as I could in regard to that of <u>Orbitolites</u>; but a comparison of
the features which present themselves in the conformation
of the structure of the <s>shell</s> calcareous skeleton of the
two types, can leave no reasonable doubt that the general
arrangement of its segments of [sarcode?] must have been
precisely the same. For the conformation of the chambers
and passages, as <s>sh</s> displayed by a horizontal section <s>in</s>
(Figs. 18, 19) shows that the animal must <s>have</s> consist<s>ed</s>
of a succession of bands of [sarcode?], each band swelling
at intervals into larger segments; that the segments of each
band usually alternate with <s>each</s> those of the bands in-
ternal and external to it so as to be opposite to the inter-
vals between them; and that the stolons which connect
one band with another pass<s>ed</s> forth from pores in the in-
tervals between the segments of one, into the segments of the
next, those of the outermost band having emerged from
the margin as pseudopodia. By the coalescence of these,
a new band would originate, which would become thick
end into segments opposite the pores of the preceding, and
would give-off its own pseudopodia from the intervals be-
tween the segments.
[<u>Note</u>. Prof. Williamson (loc.cit) has described these punc-
tations as <u>perforations</u> for the passage of pseudopodia;
but I am quite certain that such is not the case.]
