Many years ago the late Mr. Townshend M. Hall, F.G.S., of Pilton, Barnstaple, specially devoted his energies to the geology and palæontology of the Devonian rocks of North Devon, and in addition to a set of fossils acquired from him, now in the British Museum (Natural History), he left a series of local fossils to the Museum in the Athenæum at Barnstaple. This collection has been kindly curated by Mr. J. G. Hamling, F.G.S., of The Close, Barnstaple, North Devon, who takes a deep interest in the geology of the district. Mr. Hamling has called my attention to an interesting specimen in this collection which proves to be a pygidium of Bronteus, collected by the late Mr. Townshend M. Hall in the Devonian rocks of Gerolstein in the Eifel, which country he had visited many years ago in company with the late Mr. John Edward Lee, F.G.S., of Torquay. In remembrance of that excursion Mr. Hall had presented the counterpart of this fossil to Mr. J. E. Lee, and it was supposed to be in this gentleman's collection, but it cannot now be found. There is, I believe, a good cast of the fossil in the Townshend Hall Collection in the Natural History Museum.
