 Belfast. 



He very kindly examined them for Foraminifera, and in all 

 discovered twenty-three species. The results seem to show that 

 the Foraminifera occur in the most abundance in the shelly sand. 

 None were found in the overlying Boulder-clay (Specimen 4), and 

 a few only in Specimens Nos. 1 and 2. In No. 3 the Foraminifera 

 were more plentiful and of species common to the low-level 

 Boulder-clay of Lancashire, Cheshire, and the Vale of Clwyd. As 

 usual, Nonionina depressula was common, and far outnumbered the 

 other species.

The high-level drift generally does not appear to have been 

 searched much for Foraminifera. The only other published list 

 from Moel Tryfaen that I can find is that given by Miss Mary K. 

 Andrews.' 



This list was also the result of Mr. Wright's examination of 

 specimens collected by Miss Andrews. In all twelve species are
