1 D. 3661. A badly preserved stem, 16 mm. long,ybich may belong to this species. 
Hauterivian. Cressier, near Xeuchatel. Bruckmann Coll. 
D. 7087. The base of an elliptical zoarium. Base, 16 mm. x 12mm.; height, 
25 mm. ; stem above base, 10 mm. diameter ; above the fork, 9 mm. 
X 7 mm. diameter. This, being the base of an old thick specimen, 
shows the zonal aiTangement of apertm-es and mesopores very 
imperfectly developed. Xeocomian. Goslar, near Harz, Hanover. 
Purchased Dr. F. Krantz, 1898. Figs. 57, 58, p. 222.

Diagnosis. 
Zoarium with long, thin, cylindrical or flattened, dichotomously 
branching stems, about 3-4 mm. in diameter. Apertures large, 
subcircular to elliptical, in ill- defined irregular groups. The 
mesopores are suhangular or circular. 
Disteibtjtion. 
Turonian — Iser-Schichten : Trigonia beds at Brandeis, Bohemia; and 
Bovensko. 
Affinities. 
The relations of this species are uncertain. The two fragments 
in the Museum Collection are imperfectly preserved ; most of the 
fossil is silicified, and the structure retained only in places ; but 
these patches show large areas of mesopores, with the apertures 
apparently confined to transverse bands, though this character 
is not certainly established by the specimens. The hollow 
character of one specimen, some indication of lamination, and 
the arrangement of the apertures render it probable that the 
species is a Multizonopora. If so, it is most nearly allied to 
M. ligeriensis, d’Orb., which difi'ers by having stouter branches 
and more regular groups of apertures. 
D. 4439. Two long, tbin, dichotomous branches, one of which is partly 
hollow. Turonian — Iser-Schichten. Brandeis am Adler, Bohemia. 
Purchased of Dr. Anton Fric. One branch is 27 mm. long and 
3-4 mm. in diameter at the stoutest part ; it is circular and 
2'5 mm. in diameter near the end ; the other branch is 22 mm. 
long and 3 x 2*5 mm. in diameter.
