The original discovery of the Olenellus zone in Europe was made by Dr. A. G. Na- 
thorst in 1868, Ofvers Kong! Vetens. Akad Foérhandl, 1869, p. 64, in which he de- 
scribed a new and distinct horizon below the Paradoxides beds at Andrarum, Scania, 
containing trails and Lingula. The species now known as Olenellus Kjerulfi Linrs. was 
named Paradoxides Wahlenbergi by Torell in his Petrefacta Suecana Formationis Cam- 
bricae, 1869-70, p. 4, but he did not describe or figure the new species.

From an example of Nileus armadillo Moberg shows the point of attachment of the 
muscles of the antennae, hypostoma epistome and several limbs of his species; eyes 
with .3,000 to 4,000 facets. He takes exception to Lindstrom, that the macule on the 
hypostome carry organs of vision and that of the earlier Olenide were blind.
