The Faeroese specimens belong to the typical A. Montagui, though sometimes with a tendencv 

 in the direction of wax. striata, as will be seen from the measurements below:

Concluding remarks. It may be seen from the foregoing, that there is a certain regularity 

 in the variation of the species, since the form becomes elongated on the whole in the same degree 

 as the marine climate becomes more severe. At the Faeroes and the southern West Iceland we 

 have only the short A. Montagui typica, though sometimes with a tendency in the direction of the 

 slightly more elongated variety striata; at northern West Iceland the variety striata begins to appear
