Kalloclymenia frechi (Lange, 1929) from the P. jugosus Zone

at Kowala in the Holy Cross Mountains and Dzikowiec in the Sudetes.

Diagnoza

Compressed subquadrate whorls with smooth flanks, ventrolaterally oriented spines disappearing at about 20 mm diameter.

Porównanie

In the conch form the species is closely similar to K. pessoides but prominent spines impressed in the umbonal wall of the successive whorls make it similar rather to Sphenoclymenia.
