' Notes on the Culm of South Devon : Part I — Exeter District.' 

 By Frederick George Collins, F.G.S. ; with a Keport on the Plant- 

 Kemains hy E. A. Newell Ai'ber, M.A., F.G.S. , and Notes on the 

 Cephalopoda, by George C. Crick, Assoc. R.S.M., F.G.S. 



The object of this paper is to show that the fauna of the Culra 

 Measures of South Devon proves these beds to be the equivalents 

 of the Pendleside Series of the Midlands, as has been shown by 

 Dr. Wheelton Hind to be the case with the Culm Measures of North 

 Devon. The area from which these fossils have come may be 

 roughly described as a narrow strip of country 17 miles long, 

 running from south-west to noith-east, having the city of Exeter 

 as its centre. The work has extended over ten years, and innumer- 

 able sections have been examined without result. The actual 

 fossiliferous localities are IS in number, but often the fossils are 

 \oo poor for determination. Plant-remains are abundant, but 

 determinable specimens very rare ; the preservation of the frag- 

 ments is often excellent, although the fragments themselves are 

 insufficient for specific determination. Such fossils as have been 

 determined show a sequence from below upwards as we go from 

 south to north ; but it seems advisable to seek more evidence, and 

 an attempt will be made by working due north from Waddon Barton, 

 a point farther to the west, when, if the attempt is successful, 

 another communication will be offered to the Society.
