Revised description. Shell large, slender. Protoconch and first teleoconch whorls unknown. Earliest preserved teleoconch whorls bicarinate, frustate with B spiral cord in mid-whorl; flat, broad sutural ramp, slight concavity below C spiral cord. Entire whorl covered by faint spiral threads. Sutural ramp gradually passing into broad subsutural collar; B and C cords developing into prominent, rounded ribs on early spire; afterwards B cord usually disappears completely, whereas C cord continues as delicate spiral cord or faint angulation. Whorl profile changing quickly from bicarinate to straight sided and strongly telescoped with prominent concavity on late teleoconch whorls. Suture insignificant. Prominent, densely-spaced growth lines especially on adult whorls. Lateral sinus with steep angle; wide, deep, simple concave, rarely with faint inflection point close to adapical suture; adapical LS p . Broad concavity below basal angulation of last whorl, delimiting very broad, scalloped fasciole, indicating broad, incised basal sinus. Aperture largely destroyed in all available specimens. Shell measurements and ratios. No complete specimens are available; largest specimen without aperture: SL = 89.1 mm , MD = 20.5 mm . SL/MD ratio of 8 largest fragmentary specimens = 4.5, suggesting maximum SL of ~ 104 mm based on specimen Fig. 1M (representing last whorl with fasciole); AA (n=11): μ = 16.3° (σ = 1.57°), PA: μ = 11.2° (σ = 1.08°). Lateral sinus (n = 7): LS angle = 21.6° (σ = 3.9°), LS p = 1.1 (σ = 0.17), LS d = 4.3 (σ = 0.36). Paleoecology. See discussion on genus. Discussion. Stache (1858) gave a very short diagnosis of the species, comparing it with Protoma cathedralis . He therefore made the name available and is the author of Turritella carniolica , although Hilber (1893) gave a much more comprehensive description. The species is abundant in the Krško Basin in Slovenia and Stache (1858: 378) mentioned that the shells can be collected ‘ by the bushel ’. This rich material reflects a considerable variability concerning spiral sculpture. Especially the strength of the B and C spiral cords and their point of disappearance are variable. In some specimens, a spiral cord may appear along the abapical suture, fading out again on the last whorls. Similarly, the secondary spiral cords may vary in strength. The adapical spiral may appear bifurcate due to the occasional presence of a narrow spiral groove. All these features vary even within single specimens during ontogeny. Hilber (1893) separated Turritella ( Protoma ) bartelmaica from T . ( P .) carniolica based on the less slender profile, the occasional presence of a sixth spiral thread at the abapical suture and the weaker keel. Later, Mikuž (1982 , 2009 ) separated an additional subspecies as P. carniolica stachei [this name became available by the publication of Mikuž (2009) because Mikuž (1982) is an unpublished PhD thesis]. Other morphotypes have been variously identified as P. rotifera , P. cathedralis , and P. cathedralis paucicincta ( Mikuž 2009 ) . All these taxa are found co-occurring at the same localities within a limited geographic area and even Hilber (1893) recognized intermediate specimens. Therefore, we consider Allmonia carniolica to be a morphologically variable species and reject the taxonomic separation of various morphotypes. Allmonia carniolica has been confused with A. cathedralis ( Brongniart, 1823 ) , A. paucicincta ( Sacco, 1895 ) and A. rotifera ( Lamarck, 1822 ) . A separation from A. cathedralis and A. paucicincta is obvious based on the smaller size, the slender shell, and deeper lateral sinus of A. carniolica . Moreover, the deep concavity of late teleoconch whorls does not occur in A. cathedralis and A. paucicincta . This prominent concavity of the whorl profile, however, agrees well with A. rotifera . A separation of A. rotifera is based on the early teleoconch whorls, which pass from convex to straight-sided at a growth stage in which A. carniolica has bicarinate, frustate whorls. Moreover, A. rotifera develops a sharp keel close to the adapical suture, forming from a well-defined A-spiral cord, which results in a screw-like profile. Such a sharp keel is never developed by A. carniolica . Although Allmonia carniolica is described so far only from a limited area in the Paratethys, it seems to have had a much wider distribution. Several specimens from the Burdigalian to Tortonian of Portugal , described by Pereira da Costa (1867), Dollfus et al . (1903) , and Zbyszewski (1957) are highly reminiscent of Allmonia carniolica , but differ slightly in their broader shells. A specimen from the Tortonian of Sacavém in Lisbon , in the NHMW collection, however, agrees fully with Paratethyan specimens also in its slender profile ( Fig. 26E ); similarly, the Burdigalian specimen illustrated by Fonseca (1977) from the Tagus Basin can hardly be separated from the Paratethyan specimens. A biogeographic link of the Allmonia-carniolica -bearing Paratethyan assemblages with the Portuguese faunas is also indicated by the co-occurrence of the otherwise rare stromboid Pereiraea gervaisi Vezian, 1856 ( Bartol et al . 2014 ). Distribution. Central Paratethys. Karpatian (early Miocene): Várpalota and Bántapuszta ( Hungary ) ( Kókay 1972 ; Steininger et al . 1973 ) [note that Kókay (1972) and Steininger et al . (1973) considered these occurrences as Ottnangian, but Mandic (2003) documented a younger (Karpatian) age for the strata]. Badenian (middle Miocene): Krško Basin: Ivanji dol, Dolenja Brezovica , Šentjernej (= Sankt Bartlmä), Gorenje Vrhpolje (= Oberfeld), Dolenja Stara vas (= Altendorf), Šmarje (St. Marein), Škocjan , Selo, Sveta Marjeta ( Slovenia ) ( Stache 1858 ; Hilber 1893 ; Mikuž 2009 ). Styrian Basin : Klockerberg at Wetzelsdorf ( Sieber 1960 ). Pannonian Basin : Pécsszabolcs, Várpalota ( Bohn-Havas 1973 ; Kókay 2013 ). Eastern Atlantic. Along the Portuguese Atlantic coast, the species seems to be present from the Burdigalian to the Tortonian (e.g. Tagus Basin, Sacavém in Lisbon) ( Fonseca 1977 ; herein ).
