Report on Miss Holland^s Collection of Lias Fossils, 

 By Thomas Wright, M.D., F.R.S.E., F.G.S. 



Having been requested by our president, Captain Guise, to make 

 an examination of, and report upon the collection of Fossils obtained 

 by Miss Holland from the Lias of Dumbleton and its vicinity ; on 

 the kind invitation of Edward Holland, Esq., I visited Dumbleton 

 Hall on the 25th September last for that purpose. I take this oppor- 

 tunity of returning Miss Holland my very best thanks for the very 

 efficient assistance she aflforded in carefully examining every specimen 

 ■with me ; all the localities of the different species had been carefully 

 noted at the time they vrere found, this accuracy on the part of the 

 collectors, rendered our task comparatively easy, and enabled me to make 

 this report with much confidence in the general correctness of the state- 

 ments it embodies. 



The Lias beds in the neighbourhood of Dumbleton belong to the 

 Lower, Middle, and Upper Lias. 



THE LOWER LIAS. 

 The Lower Lias is exposed in a cutting near Toddington, on the Stow 

 road, on the west bank of the river Isbome, from this locality several 

 fossils belonging to the Zone of Ammonites ohtusus were found. These 

 were : — 



Ammonites obtusus, Sow. Two very good specimens. 



II stellaris, Sow. 



Nautilus striatus, Sow. 

 Gryphsea incurva, S(»o, 

 Ostrea, (nov. sp.) 



The Zone of Ammonites raricostatus. 

 This Zone is representedchiefly by the Hippopodium bed. I found, 

 however, Ammxmites densinodus, Quenst., A. Carusmses, d'Orb. 

 Orypfuea obliqua, Sow., and Hippopodivm, ponderosum, Sow.' 

 THE MIDDLE LIAS. 

 The Zone of Am,monites Capricomus. 

 This Zone is well exposed near Dumbleton Hall, in the brick-yard I 

 found many fragments of its characteristic shell ; the clay is of a good 

 quality, and is dug extensively for the manufacture of different kinds of 

 pottery. I foxind the following species in Miss Holland's collection, all 

 of which were collected from this pit.
