(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 />

Distribution. - Poland: Tortonian (Wieliczka). Austria: Tortonian, the<br />

vicinity of Baden, Vienna Basin. Czechoslovakia: Tortonian, Zidlochovice<br />

and Devinska Nova Ves. Hungary: Sarmatian, the Mecsek Mts. Romania:<br />

Upper Tortonian and Sarmatian, Moldavia. USSR: Tchokrak (Middle Miocene),<br />

the Crimea-Caucasian region; Upper Tortonian, the south-western<br />

border of the Russian Platform, the Precarpathian Foredeep and Transcarpathians.<br />
