The shallow-marine carbonate deposits of the Reuchenette Formation (Kimmeridgian, Upper Jurassic) in

northwestern Switzerland and adjacent France yield highly diverse bivalve associations, but only rarely contain

remains of pinnid bivalves. The three occurring taxa Pinna (Cyrtopinna) socialis d’Orbigny, 1850, Stegoconcha

granulata (J. Sowerby, 1822) and Stegoconcha obliquata (Deshayes, 1839) have been revised. A lectotype for

Pinna (C.) socialis was designated and the taxon is assigned herein to P. (Cyrtopinna) Mörch, 1853, the first record

of the subgenus from the Jurassic. A brief review of Stegoconcha Böhm, 1907 revealed two species groups

within the genus. Species close to the type species S. granulata are characterized by a nearly smooth anterior

shell, followed posteriorly by deep radial furrows and rows of pustules covering the dorsal flank. Another group

comprises radially ribbed species related to S. neptuni (Goldfuss, 1837). It includes among others the Paleogene

species S. faxensis (Ravn, 1902), extending the known range of Stegoconcha from the Middle Jurassic into the

Paleogene. The paper suggests a relationship between Stegoconcha and the Cretaceous Plesiopinna Amano,

1956, with S. obliquata as a possible intermediate species leading to Plesiopinna during the Early Cretaceous.

Furthermore, a possible relationship between Stegoconcha and Atrina Gray, 1842 is discussed.

On 31 July 1834 Juliusz Słowacki in the company of the Wodziński family set off from Geneva on a tour of Switzerland. He completed the first leg of journey on the same day in Bex, a village to the south‑east of Lac Leman. The following day the party visited Bex's famous salt mine and Słowacki wrote a laconic account of their excursion to the bowels of the earth in a letter to his mother. With the help of contemporary travel guides and the accounts of other travelers it is possible to fill the details of that trip. After exiting the mine, the party made their way south to Martigny.

The author presents a series of publications by Franciszek Ziejka related to his stays in France and Portugal in 1970–1973 (Aix-en-Provence), 1979–1980 (Lisbon) and 1984–1988 (Paris). At that time, Ziejka disseminated knowledge about the language, Polish literature and culture in those universities, and at the same time, in libraries and especially archives, he undertook research on the culture of these countries and the presence of Polish literature and culture. The result was groundbreaking studies on the relationships and contacts of Polish artists and writers with representatives of Western creative circles. In these studies, Ziejka expanded our traditional knowledge of the presence of Polish culture in the West and discovered new traces of it, including those sometimes associated with such famous artists as Chopin, Joseph Conrad or Zygmunt Krasiński.
