Lebour, G. A. llango of Saccwm'yia Carteri, Brady. Geol. Mag. 

 dec. ii. vol. iii. pp. 135, 136. 



In Northumberlaud, so far as known, Saccamina Carteri occurred 

 only in the Four-Fathom Limestone. In other districts it has a more 

 extended range. W. T.

Lingula Scoiica, Dav., occurs at Ridsdalo ; the author has recently 

 found Agelacrinites (Lqndodiscus) squamosus^ Meek and Worthen, at 

 EastWoodburn, in beds at the same horizon. Both these species occur 

 in the Carboniferous Limestone of Nebraska, U. 8. W. T.

The Swedish and British areas subsided simultaneously in Cambrian 

 and Silurian times ; the British area sank faster. There is less 

 difference in fauna between the Harlech and Menevian than between 

 the Menevian and Lingula Flags, or between the latter and the Trema- 

 doc group. The lowest llussian rocks are Lingula Flags or older ; and 

 the Faradoxides and Olenus beds of Sweden are oceanic. W. H. D.

The lowest deposit, loam with bones and ])ebbles, probably represents 

 the Middle Drift of the plains, washed in by the sea during a rise of 

 the land. Some subsequent deposits wore introduced through the roof, 

 and a crust of stalagmite was formed. A clay, which once nearly filled 

 the caves, seems to have been chiefly washed in through the mouth, 

 and probably represents the Upper Boulder Clay. This clay contains 

 the usual Cave Mammalia. The highest deposit is loam, with sand 

 and sea-sheUs, probably introduced, during emergence, by the sea 

 through a fissure in the roof. W. T.
