Cyclop oma spinosun. AGASSIZ. 

 PLATE XXXIV. 



A genus formed tor the reception of two species 

 only yet found in a fossil state, and principally 

 characterized by the very strong spine at the angle 

 of the opercle, and the strong armatures of the 

 preopercle, both of which are distinctly seen in the 

 accompanying representation. Both species are 

 from the schist of Monte Bolca. 



Of the discoveries of fossil fishes, in the middle 

 districts of Scotland, we hope to lay before our 

 readers some particulars in another volume of 

 this work. In the mean time, it may be remarked, 

 that for a time it was believed that among the 

 fossil fishes of the Edinburgh division of the 

 middle district of Scotland, there were teeth, 

 scales, and other parts of saurian animals ; in 

 short, that formerly we had, as natives of Scotland, 

 creatures of the crocodile kind. It has lately, 

 however, been proved, that these teeth and scales 

 were parts of true fishes, and that hitherto no 

 remains of saurian animals had been discovered
