It is almost labour in vain to describe the cxternnl 



colouring of this species, which is the ^lo^t varial)lc of tin- 



genus, and does not appear to follow any particular 

 design. The colouring of the interior of the shell is ex- 

 tremely characteristic, being with rare excc.-ption of a uni- 

 form chocolntc-bnmii. Fi--. ,i (Olin, li.jridrlln. Durlos) 

 is splashed villi triangular lilotrhes ,,f blaek-bvnwn u|,on 

 a warm ereara-eolom-ed ground. I'ig. /», a very uncommon 

 variety, is encircled with livid bhie and reddish pencil- 

 bands. Fig. c is very lightly mottled througliout with 

 black-brown. l''ig. d (Oliva stellata, Duelos) is ivory-white, 

 sparingly marked with sharp hierogly])hic dashes of violet- 

 shaded black-brown. Fig. e {Oliva Jlaveoh, Duelos) is of 

 a warm imiform orange tint. Fig. /is of a mingled ash 

 and yellow ground covered with black-brown dashes, and 

 encircled with a broad band of the same colour beneath 

 the sutures. Fig. g is of a livid ash-colour speckled here 

 and there with dark dots. Fig. h {Oliva tigrideUa, 

 Duelos) is almost entirely black-browu. Fig. / is of an 

 opake livid grey, with a few scattered dots of darker 

 colour ; and Fig. k is of a warm yellowish hue, closely 

 dotted and mottled throughout with olive and dark olive- 

 blaek. The pure white state of the species has been 

 named 0. Candida by Lamarck, whose 0. oriola appears 

 to be another variety wanting the rich chocolate-brown 

 interior. The shell tigured for 0. oriola by Duelos is pro- 

 bal)lv a variety of (>. rdicnlatn.
