Port Jackson and New Zealand.Dr. Coppinger dredged this species at the first locality in 7fathoms. It must not be confused with //. hrevis, Quoy, which is ashorter shell with more convex outlines. I would here call attentionto a few inaccuracies in Professor Hutton's English translationof the original Latin diagnosis (' Manual of New-Zealand MoUusca,'p. 122). The epidermis was described by me as whitish, not" white," and I did not say it was " shining near the vertex."The word shining applied to the whole of the surface, and isfollowed by a comma which disconnects it from the words " verticembasimque versus luteo tincto " which succeed. " Incrementi lineiset superius basique transversim subdistanter striata " is thus rendered—" transversely subdistantly striated with lines of growth, bothabove and below." Capt. Hutton makes the labrum " thin, thickenedin the middle," whilst no such thing is said in the diagnosis.The words are " labrum tenue, verticis medio junctum et ibi incrassatum."124. Akera soluta.Hah. Port Jackson {Coppinger); Philii)pines, North Australia,Zanzibar, Mauritius, Ceylon.In addition to the other synonyms of this species, I would addA. tenuis of A. Adams (Thes. Conch, vol. ii. p. 573, pi. 121. fig. 45and Conch. Icon. figs. 7 a, 7 b). I have carefully scrutinized the typeand can see no distinction. Angas (P. Z. 8. 1867, p. 227) comes toa similar conclusion. The more slender form referred to by Sowerbyin the Conch. ' Icon.' is altogether a variable character in this shell;the elevation of the spire above or its depression beneath the bodywhorlis likewise an unreliable characteristic.125. Doridium marmoratum. (Plate VI. figs. I-1 4.)Animal (in spirit) blackish, copiously mottled with a dirty buffcolour. Cephalic disk longer than wide, rather narrower in frontthan behind, with a thicliened twofold margin anteriorly and atthe sides, more expanded and simple posteriorly. Hinder dorsaldisk a little shorter than the front one, lobed posteriorly on eachside, with an intermediate sinus, with a free margin at the sides,but not in front, where it is covered by the hinder free extensionof the cephalic disk. Viewed posteriori)'', the animal is truncate,terminating in a curved expansion of the dorsal disk on each side,which conceal the gills beneatli them.
