The Localities. 

 It is necessary to say something concerning the localities 

 given on the labels now attached to the fossils. In the majority of 

 cases the specimens were without any such labels at all. But a 

 knowledge of the specimens themselves, and of the different 

 charact ers of the rocks in which they occur, has enabled me to 

 assign to the specimens not only the localities from which they 

 were obtained but also the particular rocks from which they were 

 derived. It is not contended that these labels are in all cases cor- 

 rect ; but they are possibly a very near approximation to the truth. 

 In order that such suggested localities should not appear unduly 

 authoritative, and that they should be distinguished from the actual 

 records, they have been placed within brackets. So those names 

 of localities which appear without brackets are transcriptions of 

 the actual records found on the fossils ; while those with brackets 

 are set down as suggestions from my own knowledge. 



Special Features of the Collection. 



I would now notice some of the fossils which are well repre- 

 sented, or which have some particular interest. There is a good 

 and representative series of Lias Ammonites. There are some 

 large and magnificent Lower Lias Ammonites on the floor of the 

 first case, particularly those of the genera, Coroniceras, and Astero- 

 ceras. The attention of the specialist may be directed to Coroni- 

 ceras gmuendense — Microceras Dudressieri, a large specimen but 

 with a poor centre — Microderoceras Birchi, a giant — Asteroceras 

 accderatum — Coroniceras rotator — Echioceras Oosteri, and Echio- 

 ceras tardecrescens (Dumortier, non Hauer). 



The series of Lias Belemnites is more than usually good ; 

 among them the rare Belemnites oxyconus may be found. And 

 the Upper Lias section of Belemnites is, for a general collection, 

 very well represented. 



Of Liassic Nautili there are some valuable specimens. Espec- 

 ially may be noticed Nautilus intermedius of the Lower Lias. 



From the Inferior Oolite there are some good polished Nautili ; 

 and there is quite a superabundance of polished Ammonites of the 

 Parkinsonia dorsetensis type. 



From the Great Oolite of Minchinhampton there is a Nautilus 

 of very special value : it is, at least so I conclude from comparing 

 it with the figure, the type-specimen of Nautilus subtruncatus figured 

 and described by Morris and Lycett in their '■ Monograph of the Great
