148 Mr. J. Lycett on the so-called Sands 



vados ; and, in the Mozelle, how considerable a number of the 

 species remain undetermined ! The recollection of these defi- 

 ciencies should induce us to discourage for awhile all decisive 

 conclusions, and lead us rather to compare our acquisitions 

 from time to time, carefully and rigidly subjecting them to 

 the necessary comparisons, free from the bias of preconceived 

 opinions. 



In the Cotteswolds, 56 Testacea have been obtained in the 

 upper, and 54 in the lower zone; in all, 81 species, divided 

 into, Cephalopoda, 22 ; Brachiopoda, 4 ; Gasteropoda, 9 ; Con- 

 chifera, 46. 



The following amended list of fossils from the Cynocephala- 

 stage of the Cotteswolds offers some additions and corrections 

 to those previously published, and is divided into two distinct 

 zones. 



Upper Zone at Frocester Hill, at Haresfield Hill, and at various 

 other smaller sections.
