The association of Brachiopoda strongly reminds ns of the fossili- 

 ferous group a few feet above the ball-beds at Filey ; Millericrinus 

 ecliinatus, essentially a lower passage-bed form, is also abundant in 

 both. There is moreover a strong lithological resemblance in the 

 peculiar speckled character of the stone. Altogether this is the best 

 exposure obtained in the Howardian Hills of a fossiliferous phase of 

 the junction-beds between the Lower Calcareous Grit and the 

 oolites (Corallian Limestones). They differ much from the ordinary 

 type of passage-beds (the flaggy ferruginous calc-grits) of the Tabular 

 Hills. 



A. Not much more than 2 feet of this series is observed in the 

 church quarry ; but 14 feet of it may be seen in the " old-sandstone " 

 quarry west of the village. There the group consists of thinnish 

 beds of hard white oolite, separated by alternations of yellowish 

 brash, full of Echino 1 missus scutatus, like so many eggs packed in 

 sawdust. Holtctypus is less frequent ; Ammonites cordatus may be 

 noted, and a stray Chemnitzia here and there ; but it is easy to per- 

 ceive from the barrenness of the old exposures that fossils are few. 

 It really looks as if the oolite of the Lower Limestones had come on 

 again, although we have failed to recognize it in the extreme south 

 of the Hambleton District (see fig. 17). Very similar beds, noted for 

 fine specimens of Echinobrissus scutatus and Amm. plicatilis, are seen 

 at Swinton Grange, which is nearer to Malton, and on much higher 

 ground. 



If we again seek a section showing these passage-beds into the 

 oolites above, such a junction may be observed, as at Appleton, in 

 the Brows quarry, situated in the western suburb of Malton.

The contrast between this exposure and that at Appleton shows 

 how much is due, even on the same horizon, to the accidents of dis- 

 tribution. The Brachiopoda are entirely absent (to the best of our 

 knowledge*) in c and the upper part of d. c in this section occu- 

 pies the position of the very fossiliferous passage-beds of Appleton ; 

 but there is no very marked difference in any of the beds forming 

 the group A of the quarry. The fossils noted are Amm. plicatilis 



* These beds have not been worked for some time. The quarrymen speak 

 of their containing large Ammonites.
