(Linnaeus) with Q. akneriana. According to the author's observation none<br />
of these "synonymous" forms corresponds to Q. akneriana.<br />
No such morphological variation as recorded by Gerke (1938) from the<br />
Spirialis Beds (Tchokrak horizon) in the East Forecaucasian area was<br />
observed in Q. akneriana from the Miocene material examined either<br />
from Baden or from Wieliczka. Gerke probably included a few different<br />
species, belonging even to different genera, in the range of variation of<br />
Q. akneriana.<br />
The shape of test is similar to that of recent Quinqueloculina neosigmoilinoides<br />
Vella, 1957 (n.n. for Q. sigmoilinoides Vella, preoccupied,<br />
Kennet 1966), but differs from it in having a more slender shape of test,<br />
which taper at both ends.<br />
