[None. Work starts as follows:]
The Lycorid Annelid dealt with in this paper comes very close to Nereis diversicolor O. F. Müll., as compared with the descriptions and drawings of the latter given by several authors (Malmgren, Ehlers and Schröder, &c.) and also with the alcoholic specimens from St. Andrews (Scotland) and from Foxfield in the Dudden estuary (England). However there exist some differences between the two forms, mainly in the arrangement of paragnathi. Thus in the Japanese specimens the paragnathi in the VII. and VIII. division of the proboscis are arranged in one continuous row, while in N. diversicolor they are arranged in three or four irregular rows (text-figure 1, A and B.); and moreover the falcate bristles of the former are of a greater magnitude than those of the latter (text-figure 1, C and D.)
