 Smith, Ann. $ May. Nat. Hist 1872, ix. p. 300. 



Hub. Port Jackson and New Zealand, 



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

 fathoms. It must not be confused with II . 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 the original Latin diagnosis (' .Manual of New-Zealand Mollusca,' 

 p. 122). The epidermis was described by me as whitish, not 

 "white," and 1 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 subdistantly striated with lines of growth, both 

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

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

 The words are " labrum tenue, verticis medio junctum et ibi iu- 

 erassatum." 



12+. Akera soluta.

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

 A. tenuis of A. Adams (Thes. Conch, vol. ii. p. 573, pi. 121. fig. 45 ; 

 and Conch. Icon. figs. 7«, 7b). 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 toby 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 marmc-Tatum. (Plate VI. figs. I-I4.) 



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

 colour. Cephalic disk longer 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. Foot extending the whole 

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