Mr. J. W. Kirshaw, F.G.S., of Warwick, has favoured me with several specimens of 

 Estheria minuta, var. Brodieana (January 9th, 1862), and with the following note on its 

 occurrence in the district to which he has given much attention. 



" The Estheria-bed of the Rhaetic formation is very persistent below either the ' White 

 Lias ' or the ' Firestone beds/ wherever these occur. There is generally a greenish- 

 grey clunchy marl above and below the bed. I have found this stratum in Warwickshire, 

 — in the railway-cutting north of Stratford ; at Ashton-Cantlow ; at Wilmcote (see above, 

 page 71) ; between Wootton Park and Shelfield, S.W. of Hcnley-in-Arden (whitish, 

 earthy limestone, with well-preserved Estheria) ; at Brown's Wood, Moreton-Baggott 

 (compact greyish marlstone, with Estheria well preserved 1 ) ; at the bottom of the Harbury 

 cutting on the Oxford, Worcester, and Wolverhampton Railway, near Leamington (yellow- 

 ish-grey, calcareous, laminated sandstone) ; at the bottom of Ufton Hill ; at Long-Itch- 

 ington; in Worcestershire, at Cracombe, N.W. of Evesham (grey earthy limestone^ like 



1 This Estherian rock is much like that found by boring at Wilmcote, but it is browner and less 

 calcareous.
