species, and will, I trust, help us to the means of" display- 

 ing our coUection to good advantage. 



" Many of these Fossils of the ancient strata are figured 

 in Professor Pliillips's ' lUustrations of the Ordnance Survey 

 of Coruwall, Devon, and West Somerset,' and many' are 

 unique. The coUection contains other interesting Palas- 

 ozoic Fossils, from different parts of the kingdora, as well 

 as numerous species from the Mountain Limestone of 

 Mendip, from the Goal Measures, the Lias, Oolites, Green 

 Sand, Chalk, Tertiary beds, and other strata. 



" The specimens displayed on the walls of our museum 

 are Ichthyosaurus tenuirostris, intermedius, communis, 

 parts of the huge platiodon, and a large and almost un- 

 rivalled plesiosaurus dolichodirus, which was found near 

 Watchet. Besides these, there are numerous portions of 

 saurians of the different species. One of our sjieciraens is 

 an infant tenuirostris ; another has the sclerotic, the bony 

 ring, beautifully preserved, one part of which laps down 

 on what appears to be the crystalline lens; another has two 

 masses of food preserved between the ribs ; and one is 

 especially interesting, being the identical tenuirostris re- 

 presented on plate 9, fig. 1, of Dr. Buckland's ' Bridgvvater 

 Treatise.' 



" Most of these Saurians were obtained by the late Mr. 

 Williams, from the Lias quarries of Street, near Glas- 

 tonbury. 



" A very important part of the AVilliams coUection is 

 the multitude of remains of animals from the bone cavems 

 of Mendip. Some of the caverns were explored at the 

 expense of Mr. Williams, and he was enabled to procure 

 good and abundant specimens to supply the museums of 

 London, Oxford, Bristol, etc., besides retaining the large 

 coUection which novv enriches the museum of this Society.
