from cross section, that the fossil has not an involuted struc- 
ture, that I could get rid of the suspicion that it might be a 
new type of Foraminifera allied to Fusulina, instead of an 
extraordinary coral. 
By grinding still farther in (to a depth of about 0°06 inch, 
in a specimen 0°34 inch in diameter), the lateral waving of the 
septa already mentioned, is seen to be there suddenly, and so 
strongly marked, that they connect laterally, in such a man- 
ner as to form a kind of complex inner wall between the great 
central cavity and the outer septate zone. This wall, however, 
does not completely isolate the septate outer zone from the 
central cavity, but is perforated by a series of round equal 
canals, very regularly placed one within each of the lateral 
curves of the septa, so that those on the opposite sides of each 
septum alternate with exact regularity, as do those of each 
of the two rows within each interseptal space. These canals 
have no similarity to the minute punctures of the outer wall, 
being greatly larger and very differently arranged. They do 
not pass directly through the inner wall, but are directed 
obliquely upward and inward, so that as seen in transverse sec- 
tions of the corallites, they present the appearance of a double 
row of vesicles cut across.
