UNIVALVES. 



PLATE XXX. 



Genus. BULIMUS. 



Character. Shell spiral, ovate or oblong ; columella smooth and not labiated, but 

 joined to the bottom of the cheek by a rounded base; beak not perceptible. 



Species. 



No. 1. Bulimus caeinatus. Shell irregularly striped longitudinally with dark 

 brown and pink colours; mouth carinated, of a varying green colour, pris- 

 matic, richly coloured; the columella armed with a salient angle. This 

 curious shell has been lately brought from New Holland. 



No. 2. Bulimus eximius. Shell pale brown, striped with white; the mouth green, 

 prismatic, richly coloured ; the whole displaying a chaste and elegant effect, 

 and a pleasing contrast. A native of Van Diemen's Land, and drawn from 

 a specimen in the Museum of Mr. Murrow. 



No. 3. Bulimus zebra. Shell of a dark brown, with irregular longitudinal streaks, 

 resembling the Zebra ; the mouth wide, and curved on the columella. A 

 native of the Friendly Isles and New Zealand. Drawn from a specimen 

 in the British Museum. 



No. 4. Bulimus phasianus. Shell of a lively red, veined with white, and richly 

 shadowed, like the breast of the pheasant ; mouth wide and expanded. This 

 is one of the most beautiful shells recently discovered in New Holland, and 

 is found on the banks of the largest rivers in that country. It is now very 

 commonly known, nevertheless, it is held in much esteem by Collectors, from 

 the elegance of its form and colours. 



No. 5. Bulimus lineatus. Shell white, inclining to yellow ; mouth white ; colu- 

 mella of a pink colour. A native of the East Indies and the Cape of Good 

 Hope. From a shell in the Museum of Mr. Bullock. 



REMARKS. 



The genus Bulimus has been established by M.Bruguiere, an eminent French Conchologist, 

 who has shewn the propriety of separating it from the genus Bulla, with which it had been 

 erroneously placed by former writers. Its characters are indeed very peculiar and striking, 

 for it is quite destitute of a beak or channel, and instead of that, the bottom of the mouth 

 is of a rounded form. It has a considerable resemblance to the genus Melania, but diners 

 from it in not having a thickened margin or rim surrounding the edge of the mouth. Like 

 the Trochus, the shells of this genus are frequently distinguished by a beautiful prismatic 

 changeable colour in the opening of the mouth, an effect which it is very difficult to express 

 tolerably in painting. They are chiefly found in the Southern Ocean, and may be considered 

 as forming a beautiful assemblage or family allied distantly to the Buccinum, so familiarly 

 known in the European seas. There is also a smaller species of the Bulimus phasianus, 

 the pattern or marks of which are exactly similar to the one here represented, though its 

 shell is rather thicker ; it may therefore be denominated the Bulimus phasianus minimus of 

 the before mentioned genus.
