by 1 1 .nu-r. and I . // Geyer, a dwarfed species. Amm. spiralusimum, 



Hauer, occurs in company with I in the Lower Bucklandi bed al Enzea- 



feld ; Imt this i- probably a species of Caloceras, similar to Cal. of the 



ety which occurs in the Bucklandi horizon in South Germany. 



V il give au\ species of this genus as occurring in 



the Oil mountains, and this is also the case in several other localities 



where 1 1 » « - formations are sufficiently well developed to lead one in expect thai 

 iiiis would be represented if at all-common in tlii* province. CaL prespira- 

 a, in the Angulatus bed of the Kammerkahr Alps and Adneth, as given bj 

 Wahner, 1 is the only example of a transitional form. Nevertheless tin- great

 transitional forms probably occurred in thai province.
