 EDITORIAL NOTE

Professor T.H. Huxley at one time proposed to undertake the description of the Cephalopoda brought home by the Expedition. His many engagements, however, compelled him to give up this intention, so far as regards the whole collection, but he retained, and is now engaged in the preparation of a report on, the genus Spirula. The remainder of the cephalopod collection was placed in the hands of Mr. W. E. Hoyle, in 1883, soon after his appointment as Naturalist on the Editorial Staff of the Challenger Reports.

The results of Mr. Hoyle's investigations are given in this part, which, in addition to the description of many new forms, will be found to contain an able revision of our knowledge of existing species up to the present time.
