The number of scales is uncertain, though four pairs remained. Most iiad five cilia on the outer border, though one, probably the first, had seven. Lines radiating from the centre of the scale to the base of the cilia probably indicated nerve-strands. The feet show dorsal and ventral divisions each with a spine and tlie characteristic bristles. The life-history of this form thus corresponds with that of its allies, the larval stage being pelagic, the young by-and-by settling on the bottom like their parents. A wide distribution is thus attained. 2. On the British Nephthydidas. In the ' Catalogue of the British Museum,' published in 1865, three species of Nephthi/s are mentioned, viz. N. cccca, Fabr., N. longisetosa, ffirst. (?), and A^. Ilombergii, Aud. & Ed. Dr. Johnston, however, had not seen an example of the latter, which had been mentioned by Dr. Williams, and the precise.
