On a Gyrodactylus Species from Northern Sweden and the Subgeneric Position of G. hrabei Ergens, 1957 (Trematoda, Monogenea)

A Gyrodactylus species from northwestern Sweden is described. Because only one specimen of the species was found no specific name is given. The type of protonephridial system of the new species showed that it belongs to the subgenus G. ( Paranephrotus ). Because of the strong resemblance between the new species and G. hrabei Ergens these two species are placed in a new species group: the G. hrabei-group. The Eurasian fresh water fauna seems to have very few representatives belonging to G. ( Paranephrotus ) and because of this the above find is of special interest.     

Some dasyclad algae of the sinemurian from the north-western iberian chains (Spain)

In a section of the Liassic southwest of the village of Préjano (Prov. Logroño) Sinemurian Dasyclad algae were found for the first time in the “Bankkalk-Series” of the “Carniolas-Formation” which is not dated up to that time. Six species,Dissocladella lucasi (Cros & Lemoine),Dissocladella iberica nov. sp.,Dissocladella ebroensis nov. sp.,Sestrosphaera liasina Pia,Gyroporella retica (Zanin) andMacroporella nov. sp. aff. sturi Bystricky are described.     

The mongolian game Norobo or Cindi

Current debates over the concept of culture are examined, especially with regard to the relationship of culture to bounded collectivities, human nature, and individuality; present‐day views are seen against the background of back‐and‐forth swings in the history of anthropological thought. Recent theorizing about cultural acquisition is also considered.
