Shell stout, long oval, of a brown chesnut colour, changing to red at 

 the apex and on the upper whorls, which last are longitudinally striped 

 with reddish brown towards the suture. Whorls six, ventricose ; the last 

 has a narrow black band across its middle, and another of the same 

 colour close to the suture, which is white ; the last whorl but one has two 

 narrow black bands, both near the sutures ; the lower bands on the last 

 and penultimate whorls are each thrice interrupted. On the last whorl, 

 near the base, which is very dark, is a faint, broad, lighter coloured band. 

 The columella is remarkable for its obtuse white tooth, surrounded by 

 the rich dark colouring of the aperture. The right lip is of huge thick- 

 ness, and much reflected : above, it is of a Hght chesnut colour ; below, 

 of a rich bro\vnish japan- like black, which, particularly where it is shad- 

 ing off into the chesnut, gives, when the Hght is thrown full on it, the 

 same kind of iridescent appearance as is seen in the Lumachella, or Fire- 

 marble. The lower edge of this rich lip is punctured pretty thickly with 

 dots, resembhng those of Cypraea testudinaria, which seem filled with a 

 whitish opaque substance, and the formation of which has given an irre- 

 gular, and almost fungus-like appearance to the reflected border of the 

 lip, on its upper side. The interior of the aperture is white. Length 

 three inches ; breadth, measured across the body whorl, and including 

 the lip, one inch and six-eighths. 



This fine shell, of a much firmer fabric than most land-shells, was 

 obtained by Lieut. Maw, R.N., in a rancho (farm-house) at Toulea, about 

 nine leagues to the eastward of Chachapoyas, in Peru, on Christmas-day, 

 1827. It had been taken on the chacra (farm) to which the rancho be- 

 longed. The chacra is situated at the highest limit of the montana, or 

 woody district, on the eastern side of the Andes, at an elevation of about 

 8000 feet above the level of the sea. The species was frequently seen 

 by Lieut. Maw in the woods between Chachapoyas and Moyabamba. 

 Two of a much larger size than the individual here described, were foimd 

 by him alive, and given in charge to the ariero (muleteer), with a special
