MILIOLIDAE - Acta Palaeontologica Polonica

MILIOLIDAE FROM MIOCENE OF POLAND 7
Attempts were made to base the identification of species on materials
from the type localities, from which they had been described originally
or on materials obtained from the deposits of the same age in the neighbouring
area. This is especially true of the species erected by earlier
authors, like d'Orbigny, Reuss or Karrer, whose orginal materials were

Fig. 2. Test morphology of Miliolidae: A. Chamber arrangement and dimensions.
1-3 - Quinqueloculina, 4-6 - Pyrgo; 1,4 - front side, 2,5 - back side, 3,6 - apertural
view; I, II -last chambers, III, V - central chambers (or middle chambers) of the
front side, IV - central chamber of the opposite side (succession of chambers beginning
at the last one); a length, b breadth, c thicknes, d width of the chamber, e aperture
edge, f basis of the aperture, g tooth, h periphery or edge. B. Shapes of tests.
1- broadly oval, 2 - oval, 3 - elongate oval, 4 - elongate or slender, 5 - rhomboid,
6 - rectangular or quadrangular, 7 - equilateral, 8 - sigmoid, 9 - ovoid.
C. Periphery outline. 1 - rounded, 2 - subrounded, 3 - subacute, 4 - acute, 5-
keeled or carinate, 6 - quadrate, or angular, 7 - truncate, or subangular.
inaccessible to the author. She was in a position to see the holotypes and
paratypes of some newer species personally, e.g. those described by Bogdanowich,
Serova, Pishvanova, Didkovsky and Venglinsky. In this connection,
the following symbols are placed beside the names of species:
* - species identified on the basis of comparison with the holotype
X -
(homeotype),
species identified on the basis of comparison with specimens from
the locality and horizon in which the holotype was found (topotype),
+ - species identified on the basis of materials of the same age as the
holotype and from the same horizon, but from another locality of
the same region, and
= species identified after a consultation with its author.
