123. Haminea cuticulifera. (Plate VI. fig. H.) 

 Smith, Ann. Sr Mag. Nat. Hist. 1872, ix. p. 350. 



Bab. Port Jackson and New Zealand. 



Dr. Coppinger dredged this species at the first locality in 7 

 fathoms. It must not be confused with ff. brevis, Quoy, which is a 

 shorter shell with more convex outlines. I would here call atten- 

 tion to a few inaccuracies in Professor Hutton's English translation 

 of theoriginal 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 is 

 followed by a comma which disconnects it from the words " verticem 

 basimque versus luteo tincto " which succeed. " Incrementi lineis 

 et superius basique transversim subdistanter striata " is thus ren- 

 dered — " transversely subdistanfcly striated with lines of growth, both 

 above and below." Capt. Hutton makes the labrum " thin, thickened 

 in the middle," whilst no such thing is said in the diagnosis'. 

 The words are " labrum tenue, vertieis medio junctum et ibi in- 

 crassatum." 



124. Akera soluta. 



Ifab. Port Jackson (Coppinger); Philippines, North Australia, 

 Zanzibar, Mauritius, Cej-lon. 



In addition to the other synonyms of this species, I would add 

 A. tenuis of A. Adams (Thes. Conch, vol. ii. p. 673, pi. 121. fig. 45 ; 

 and Conch. Icon. figs. 7 a, 76). I have carefully scrutinized the type 

 and can see no distinction. Angas (P. Z. S. 1867, p. 227) comes to 

 a similar conclusion. The more slender form referred to by Sowerby 

 in the ' Conch. Icon.' is altogether a variable character in this shell ; 

 the elevation of the spire above or its depression beneath the body- 

 whorl is likewise an unreliable characteristic. 



125. Doridium marmoratum. (Plate VI. figs. I-1 4.) 



Animal (in spirit) blackish, copiously mottled with a dirty buff 

 colour. Cephalic disk loager than wide, rather narrower in front 

 than behind, with a thickened twofold margin anteriorly and at 

 the sides, more expanded and simple posteriorly. Hinder dorsal 

 disk a little shorter than the front one, lobed posteriorly on each 

 side, with an intermediate sinus, with a free margin at the sides, 

 but not in front, where it is covered by the hinder free extension 

 of the cephalic disk. Viewed posteriorly, the animal is truncate,- 

 terminating in a curved expansion of the dorsal disk on each side, 

 which conceal the gills beneath them. Poot extending the whole 

 length of the animal, with a duplex margin in front below the
