Kettneraspis sp.

Text-fig. 4h

M a t e r i a l. One isolated free cheek, negative counterpart.

R e m a r k s. One isolated free cheek does not enable exact affiliation, but most probably belongs to Kettneraspis pigra ( BARRANDE, 1872) . Genal spine is long, with robust base. Ten to eleven marginal spines are relatively slender and pointed (rather blunt in K. pigra ). The surface of the free cheek has fine granulation; the eye is broken off. Preservation of the specimen makes precise determination impossible.
