ESTIIERIA MINUTA. 



71 



In his work on 'Fossil Insects,' at page 82, Mr. Brodie also notices the existence of 

 a band of white stone with " Cyclas ?" in the cliff at Aust Passage, on the Severn, about 

 twelve miles from Bristol, and this he refers to the Estherian zone of Westbury and 

 Wainlode, or what he terms the " Cypris-bed." And at page 72 Mr. Brodie mentions 

 that Mr. H. E. Strickland found " the yellow Cypris-limestone with Cyclas," at Dunham- 

 stead, on the line of the Gloucester and Birmingham Railway, near the Droitwich station. 1 



Other sections of the Rhastic beds in Warwickshire and elsewhere are described by 

 Dr. T. Wright in his paper ' On the Lower Lias and Bone-bed/ already referred to. 

 Thus, at pages 386 and 387 we find the following section of Messrs. Greaves and Kirshaw's 

 quarry at Wilmcote, near Stratford-on- Avon : 



Beds Nos. 1 — 20. — Clays, shales, and limestones, belonging to the zone characterised by Ammonites 



planorbis.

2 Mr. Kirshaw has favoured me with a specimen from this Estheria-bed. It is part of a nodule of 

 grey compact limestone, traversed by a band of Estheria, both well preserved and in fragments.
