Ammonites Gardeni has a very wide geographical distribution. The 

 specimens originally described by Baily were from Cretaceous deposits 

 in the neighbourhood of Natal, and the species has since been found in 

 rocks of similar age at three different localities in Southern India. Dr. 

 Stoliczka thinks that the Ammonites sulcatus of Kner, from Lemberg in 

 Austrian Poland, may be synonymous with A. Gardeni, and if this be the 

 case the latter shell occiu's also in Europe. The four Ammonites from 

 the above mentioned localities in Vancouver Island are referred to A. 

 Gardeni with some confidence.
