A peculiar species of trilobite, called Brontes flabellifer ([fig. 407.]), is found in the Devonian strata of the Eifel and in South Devon. It should be observed, however, that the head in the specimen here figured by Goldfuss, the most perfect which could be obtained, is incomplete, and a restoration has been attempted by Mr. Salter in [fig. 408.], from data supplied by other species of the same genus occurring in older rocks.
