Dr. Karrer, in his paper on the Miocene Foraminifera of Kostej, figures an anomalous 
shell as Cristellaria pleurostomelloides. There is, doubtless, some good reason for placing 
it under the genus Cristellaria ; but, judging from the figures, we should have inclined 
to regard it as much more closely related to the group under consideration. ; 
Distribution.—Setting aside the references to Ehrenberg and Terquem as unsatisfactory 
in the highest degree, we have no record of Polymorphina nodosaria except as a Tertiary 
fossil. The Middle Tertiaries of Central Germany, the Crag of Antwerp, and the Crag of 
the East of England are the only localities for the species, so far as our present knowledge 
extends.

Characters.—Shell oblong, ovoid, subeylindrical, gibbous, rounded at the base, more 
or less produced at the apex. Chambers numerous, broad. Septa marked by lines only, 
neither constricted nor excavated. Orifice simple, round, oval, or radiate. Surface 
smooth. Length 35 to 55 inch. 
Out of a large number of figures of compact, oval, Guttuline Polymorphine accompany- 
ing Dr. Bornemann's paper on the Microzoa of the Septaria-clay of Hermsdorf, those of 
Guttulina rotundata, from which the subjoined Woodcuts are copied, appear to represent 
Guttulina rotundata, after Bornemann. 
the best-developed specimens; and as the range of variation in the whole series is not 
more than is often found within the limits of a single variety, we have placed a number 
of them together under this head.
