Rhoetics ),* between the Lias and the Trias ( New Ecd 

 Sandstone ) may be interesting to the Geological members of 

 this Society. The Harbury section, lately amended and 

 accurately measured, will enable our readers to correlate it 

 with the contemporary zone at Kineton and elsewhere. A 

 few remarks are added with reference to a further continua- 

 tion of the Rhoetics, mainly to the East and North in 

 Leicestershire, Nottinghamshire, Lincolnshire, and York- 

 shire, which shows a larger extension of this formation and 

 probably co-extensive with the lower Lias in the same 

 direction, so that their presence in most cases under the 

 lower Lias may be inferred in its range from the coast of 

 Dorsetshire to that of Yorkshire, including a small outlier 

 S.E. of Carlisle, a larger expansion of the Rhoetics than 

 has been hitherto recorded. The '•Insect bed' at Knowle 

 is also indicated, its fui Lhest northern limit in this county, 

 with the exception of the occurrence of this stratum. 



A short distance from the Railway Station at Stratford- 

 on-Avon, on the branch line to Fenny Compton, the red 

 marl (New Red sandstone) appears with overlying Keuper 

 sandstone, capped by the usual glacial drift. The lower Lias 



* The Khoetics are so termed from certain similar strata in the Austrian Alps, 

 (EhcEtia) where this foi-mation composed of various limestones, sandstones, and 

 shales with many peculiar fossils is more than 4000 feet thick, while in England it 

 rarely exceeds 100 and is often much less. The shells are for the most part of 

 small size but highly characteristic; many of the British species are new, others 

 the same with Continental species, a few agree with those well known in the 

 Lias. In all prohahility it was a deposit intermediate between the New Red 

 Sandstone and the Lias, having zoological affinities with both, and some foi-ma 

 specially characteristic. The recent discovery of Labyriuthodont? remains, should 

 they prove to be so, near Leicester, in conjunction with the majority of the flsh in 

 the boue bed, which have a nearer affinity to Triassic than Liassic genera, so far 

 connects it more closely with the former ; but on the whole it may fairly be con- 

 sidered as an independent formation not fully represented in this country, but 

 largely so in Austria. The Geological Survey have given the name of Penarth to 

 this deposit, from the famous type section on the Welsh coast; but as I believe the 

 term Ehcetic was adopted first, and the development of these beds in the Austrian 

 Alps is so much greater, it seems preferable to retain it, and it is now very 

 generally adopted.
