 fair preservation except on the fifth and last whorls, where small 

 portions have come away in the separation of the rock.

 the species inferred I presume from the imperfect cast and the 

 marks of striation remaining in the matrix. The italics are mine.

 spire, the apex of which is subject to decollation: the seven 01 eight
