II. The zone of Ammonites calloviensis, or Kelloway Rock, 



was first discovered by Dr. William Smith, at KeUoway 

 Mil], Wiltshire, and afterwards in situ in tlie Castle Hill, 

 Sca4orotigli. This is the true con-elative formation to the 

 Marnes co.lloviennes and Calcaires mameux, of Mr. Maktin.

My old esteemed friend, J. Leckenbt, Esq., T.G.S., of 

 Scarborongh, has conti'ibuted a valuable paper on the Kelloway 

 Rock of the Yorkshire coast,* and which I quote here as an 

 important addition to my very imperfect notes on this formation 

 in Wiltshire. It is seen in the cliff to the south of Gristhorp 

 Bay, the projecting point of Red Cliff, and at the Castle Hill,
