SPIRIFERA. 23 



the Devonian period (' Stringocephalen-Kalk ' of the Germans), but had not been noticed 

 as a British fossil until the month of April, 1863; when I had the good fortune to discover 

 one or two small incomplete examples among some fossils sent me by Mr. Champernowne, 

 which he had obtained from a quarry on his estate of Dartington, near Totness, in 

 Devonshire. The upper beds of the Dartington band of limestone contain the Uncites ; 

 and it is found likewise a little lower down in a dolomite, which is partly decomposed, 

 forming quite sandy masses. Along with the shell under description I recognize the 

 following species ; — Spirifera nuda, Sp. octoplicata, Atrypa redicularis and A. aspera, Pen- 

 tamerus brevirostris, Bhynchonella primipilaris, and B. implexa, and one or two others not 

 sufficiently perfect to warrant a correct specific determination being arrived at. A larger 

 and perfectly characterized species of the shell under description has also been discovered 

 by Mr. Vicary, in Lane's or Woolborough Quarry near Newton Abbot. The British 

 examples of Uncites hitherto discovered are small, however, when compared with others 

 which I have picked up in the neighbourhood of Paffrath, and at Klustein near Gladback, 

 in the vicinity of Cologne, and which attained nearly two and a half inches in length. 

 Von Buch states that it is small at Gerolstein ; and I have it also from Nimes in Belgium. 

 Dr. F. Sandberger gives an excellent figure of a specimen he found in the Devonian lime- 

 stone of Nassau.
