Catalogue 412S (Ottawa). Three fragmentary or immature si)e(imens were obtained by tlie exi)e(lition at Point Harrow; a description has been prepared from an adult in the collection of the r. S. National Mu.seum. The shells, as in many other species, some- times show narrow oblicpie or zigzag ridges due to some cause not yet determined, but probably abnormal. The s])ecies in a general way recalls 1'. atstaiiKt Morch, a much smaUer species conunon on the .Meutian islands. The species is named in honour of the commander of tiie Canadiui .\rctic lAi)edition.
