relation between the impressed and elevated examples of 

 Oldhaniia, should be carefully noted ; thus, in a number of 

 cases at au}^ rate, on the upper surface of a slab O. radiata 

 appears as a depression, while O. atitiqua is in relief; nor does 

 the latter seem to lie alwa^'s on a plane of bedding, since it 

 branches continually over irregularities of the rock. Like so 

 man}^ reputed ancient organisms, Oldhamia stands upon its 

 trial ; and the jury should assuredly" be called from the 

 naturalists of Co. Dublin, who are in a position to examine 

 minutely the scenes of its alleged career.

THE COLEOPTERA OF THE ARMAGH DISTRICT. 



BY REV. W. F. JOHNSON, M.A., F.E^.S. 



In compiling the following list I have confined mj^self to 

 the area contained within a five-mile radius of the city of 

 Armagh. The greater number of the species have, however, 

 been taken within two or two and a-half miles distance. 



The surface of the district is of an extremely undulating 

 character, so that while there are not any great heights, there 

 is scarcel}^ any level ground of large extent. The general 

 surface rises towards the south in the direction of the Vicar's 

 Cairn, and falls towards the north in the direction of Eougli- 

 gall. The geological formation is almost entirel}' Carboniferous 

 Limestone. " . -•
