Fragments of an Ästarte have been obtained from a light- 

 coloured sandstone block, which was found by 0. Nordenskjold 

 in Aucella River in the south-west of Jameson's Land. The 

 sandstone-block was found below the place where the Aucella- 

 sandstone crops out. The best-preserved specimens show a 

 close resemblance to those of Ästarte Sœmanni in a Kimeridge- 

 Portland boulder from Hirshals in Denmark, in the Copenhagen 

 Collection ^). The sculpture of the shells is somewhat coarser 

 and the edges do not seem to have been crenulated. Specimens 

 of Ästarte Sœmanni from the Portlandian of Boulogne, in the 

 Munich Collection, are also very similar to these. 



The sculpture of the valves recalls at once that of Ästarte 

 ovoides v. Висн^), specimens of which, from Khorochovo near 

 Moscow, are in the Copenhagen Collection. The shape of the 

 latter is, however, very much more oval than that of the Green- 

 land Ästarte^ which certainly stands nearer to Ästarte Sœmanni 

 than to Ästarte ovoides. 



Ästarte Sœmanni occurs in the «Marnes à Perna Bou- 

 chardin or «zone à Virgatites typiques» (sosia, apertus etc.) 

 of the «Portlandien» of Boulogne-sur-mer, and in the Lower 

 Portlandian (Portland Sand) of Wiltshire and Buckinghamshire 

 in England.
