is, however, not a Bryozoon. The other was Heteropora tuherosa 
(Verst, nordd. Oolithgeb. p. 12, pi. xvii. fig. 16), which is 
a Heteropora. C. tuherosa could therefore stand ; hut as Edmer’s 
C. constricta had been simultaneously founded on von Hagenow’s 
account of C. stellata, its name would stand, and would in any 
case have preference of C. strangulata. The species is characterized 
by the distribution of the apertures being irregular in some parts 
of the zoarium and by the absence of the external ridges of 
C. articulata.
