order the Trigonia grit comes first into view, then a bed about 

 eight feet in thickness, without any distinctive fossil, so far as we 

 could discover, and then the " freestone,* 1 which is at that point 

 about CO or 70 feet thick. The Fimbria bed appears to be totally 

 unrepresented. Below the " freestone," the Cephalopoda bed, and 

 the upper portion of the subordinate " Sands," come into sight ; 

 but the beds, intervening between these and the base of " the 

 freestone," are obscured by rubble. 



The " Sands " were here tenanted by a colony of Mason- 

 wasps, Odynerus spinipes, accompanied by their parasite Chrysis 

 bidentata. 



After breakfast the party, with a considerable addition to its 

 strength, proceeded to Peakdown, in a road-cutting on which is 

 displayed the best section of the Supra-liassic Sands yet visited 

 by the Club, as they here attain to an estimated thickness of at 

 least 200 feet. Upon these reposes, well-exposed, the " Cephalo- 

 poda bed " with all its characteristic Ammonites, with the addi- 

 tion of many other interesting fossils, of which the following list 

 was made : 



Ammonites jurensis. 

 variabilis. 



radians and var. Thouarsensis* 



opalinus and var : Moorei. 



Belemnites irregularis. 



abbrieviatus. 



Nautilus inornatus. 



Trigonia Ramsayi (Casts). 



Opis. 



Astarte. 



Turbo capitaneus* 



Pholodomya Zietheni. 



Pecten demissus. 



Cucullcea. 



Gresslya abducta. 



Modiola plicata* 



Lucina. 



Serpula* 



A large Pinna and Ceromya bajociana, with other fossils, were 

 found in the upper portion of this bed ; but, as at Haresfield and 

 Frocester, these have all been found only in the upper zone, and 

 as it was exceedingly doubtful whether they were here in situ, to 

 say nothing of the very doubtful character of the matrix in which 

 they were embedded, the Secretary decided upon rejecting them. 

 While the majority of the party remained here, the President, 

 Secretary, and others crossed the intervening valley, and made 

 for Uley-Bury. About half-way up the hill, and at about the 

 middle of" the Sands "before referred to, the Secretary discovered 

 an intermittent nodular band of brown stone, similar to that
