Whilst the various mines and mineral deposits I have examined have 

 certain species in common, it may be said that they have each special palte- 

 ontological featui'cs of their own. 



In the Keld-Head Jliues organic remains are very abundant at about 

 450 feet from the surface, amongst which are many Foraminil'era, chiefly 

 of the genus Livolutina, of which there are six species, and univalves of 

 about twelve genera, the freshwater genera Valvata anomala, Moore, and 

 Planorbis Mendipensis, Moore, being present, and also Entomostraca of 

 several new species. 



The Fallowlield mines, although not yielding a very long list of species, 

 have their special interest in the presence of the laud and freshwater 

 geneva, Stoastoma'? , Hydrobia, and Pisidium ; Involutina, as in the Keld-Head 

 mines, though rarely ; and a single seed of the Flemingites gracilis, Carr. 

 The richest samples from this mine are at 90 and 450 feet from the surface. 



The Grassington mines are not oiily very rich in individual specimens, 

 but have yielded the greatest number of species, amongst which are again
