Station 167a. June 27, 1874. Lat. 41° 4' St, long. 174° 19' E. Queen Charlotte 

 Sound, Cook Strait, New Zealand. 10 fathoms. Mud. 



Habitat. — Pacific (Swainson), New Zealand (Augas and Hutton). 



The Challenger specimen is young, and has the ribs finer, more prolonged, and more numerous 

 than the British Museum specimens ; but is, I have no doubt, the species these represent, which it 

 may be well to observe is not Voluta gracilis of Wood (Ind. Test. p. 209, Suppl., pi. iii. fig. 2) 

 = Voluta magellanica, Sow. — (if not a variety of that of Chemnitz, which Mx Hanley denies) — nor yet 

 the Voluta gracilis of Gray in Griffiths' An. King., vol. xii. pp. 72 and 601 , pi. xl. fig. 4, which seems 

 to be a variety of Voluta pacifica, Solander. Sowerby (Thes. Conch., vol. i. pt. 5, p. 206, sp. 32, pi. 

 lv. figs. 117, 118) seems to have had before him this species figured by Gray (loc. tit.), and not 

 that of Swainson. This was, I think, also the case with Cox (Distrib. Austral. Volutes, p. 21, 

 sp. 45), and with Tryon (Manual, vol. iv. p. 94, pi. xxviii. fig. 99). I have quoted Quoy and 

 Gaimard above for Voluta fusus, and also Kiener with hesitation for both. Kiister (Conch. Cab., 

 p. 159, pL xxxvi. fig. 4) and Kobelt (Jahrb., p. 309) regard that species as the young of Voluta 

 elongata, Swain, (which the latter further regards as the young of Voluta pacifica, Sol.) At the 

 same time, the figures of Quoy and Gaimard seem rather to suggest Voluta gracilis than Voluta 

 elongata. In referring to Sowerby's Voluta gracilis, Thes. Conch, (loc. tit.), it may be well to call 

 attention to the extraordinary confusion of his reference there to Kiener.
