resemblance to the shale of the Coeioma-bed, and that there is 

 therefore some probability of the latter bed being older than 

 the former. Against this the objection cannot be raised, that 

 in addition to the bits of shale, the concretions of the shale 

 ought also be found in the sandstone, because these may have 

 been formed in the shale at a much later period. 



Neither would I dare to draw a positive conclusion from the 

 fossils found, regarding the respective ages of the two beds, but 

 as may be seen from the accompanying Hst of fossils, the two beds 

 seem to have two species in common viz. the species which I have 

 above assigned as Cryptodon cfr. unicarinatus Nyst, and Äporrhais 

 speciosa v. Schloth. sp. We may therefore presumably be right in 

 supposing that the two deposits do not differ much with regard 

 to age. To the question of the age of the Tertiary deposits at 

 Кар Dalton I shall return later on.
