Geol. Soc., vol. xxvi. p. 354, vol. xxix. p. 296 ; Judd, Geol. Kutlaud, pp. 276, 
&c. ; E. T. Newton, Geol. Mag. 1891, p. 493 ; and S. S. Buckman, Ibid,, 
1892, p. 258. 
The Northampton Sand, where fulljv developed, represents the 
upper part of' the zone of Ammonites jurensis, ihe zone of A. 
opalinus, and portions of the scone of A. Murchisoncc. There is 
at any rate no evidence of the beds with A. striatulus, so that, ns 
remarked by Sharp, we may have only a portion of the passage-beds 
between the Upper Lias and Inferior Oolite repri sented in these 
strata.
