Isopoda.

Cirolana rossii, Miers. Cat. N.Z. Crust., p. 109; Index Faunæ N.Z., p. 263.

One small specimen, dredged off Great Barrier Island, appears to belong to this common species, but it is immature, and the eyes very indistinct, so that the identification is not free from doubt.

Among the Isopoda were two or perhaps three species of Sphæromidæ, one apparently belonging to the genus Cilicæ, and new to New Zealand. But I cannot identify these with existing species, and do not care to venture on the description of new species of this difficult family pending the appearance of Dr. H. J. Hansen's work on the genera of the group.
