ornament. Costae reflected also on inner surface of shell. Remarks — In STOLICZKA's (1861) original material three specimens have been found under the name "Turbo Hörnest"

. However, they belong to two different species and to two different genera. Two specimens have shells with growth-lines as the only basal ornament, but a last whorl fragment has also spiral carinae. The morphology of the peristome and the shape of the growth-lines are also different (see Figure 81, and description of Scaevola? suissenseensis n. sp. below). The two specimens, similar to each other, are regarded here as the name bearing types of "Turbo Hörnest STOLICZKA, 1861". The generic identification is problematic because of the poor preservation, but the circular aperture delimits the possibilities to four genera to be discussed. The habit of whorls shows similaritv to those of Cirrus and its subgenera, however, the costae do not extend beyond the peripher)' towards the base; in this character, the shells are similar to Spirocirrus, Scaevola and Hamusina; only the latter one is said to be anomphalous, that is why this genus name is selected, however, the open usage is necessary owing to the dissimilarities in the ornament of the whorls. Distribution — Schafberg over St. Wolfgang, (Austria), Upper Pliensbachian.

Name — From the Suissensee, a small lake beneath the Schafbergspirze, along the structural line where the gastropod bearing fissure-fillings can be found. Diagnosis — Low spired shell of rapidly expanding whorls; base slighdy convex, and having narrow (Ppseudo-)
