(e) Concerning- some of Wriglit's figured Ammonites. 



To Yol. iii of the ' Proceedings of the Cotteswold Xatnralists' 

 Field Club,' parts 2 & 3, published in the ^^ears 1864^-1865, Wright 

 contributed a ]3aper ' On the Ammonites of the Lias Formation ' 

 (pp. 162-79, 235-45) describing various species illustrated in 

 four quarto plates, drawn hj J. W. Salter. In his subsequent 

 iMonograph he makes no reference to this prior work ; and yet the 

 descriptions therein of the species concerned are almost Avord for 

 word identical — just a few alterations like millimetres for inches, 

 changing one technical term for another, and occasionally a few 

 additional remarks ; while the figures of the species are in very 

 man}^ cases apparently not redrawn from the specimen, but merely 

 copies of the illustrations in the prior j)aper. 



The search for information as to the localities of certain of 

 Wright's specimens, in connexion with the discussion on the 

 Bredon fauna referred to above (p. 312), led to the discovery that 

 the Cotteswold Club paper was important for the understanding of 

 Wright's Monograph, for the identification of some of his species, 

 and for the recognition of some of his figured specimens, several of 

 which do not seem to have been found. Therefore I append the 

 following notes, commencing with a list of the species figured in 

 the Cotteswold Club paper, marking those which are refigured 

 in the INionograph.
