Description of an unusually complete specimen of Megalichthys Hibberti. found 

 in the roof of the Halifax Hard Bed at Idle. It is externally in good preser-

Hugh ]\Iiller. 



On Fluxion-Structure in Till. Geol. ^lag., October, New Series, Decade 

 HI., voL i., pp. 472, 473. 



A rough structure comparable to the fluxion-structure of igneous rock, the 

 smaller boulders diverging around and apparently drifting past the larger, 

 indicates that at least a surface layer of the Till was dragged along, with a 

 shearing movement of particle upon particle, producing intimate glaciation 

 within its mass.

Under' the letter N is a slight general sketch of the physical geography and

 views of the late George Tate as to the divisions of the Carboniferous Series 

 are well described : later work, both by the author himself and by others, 

 being practically ignored.
