Inhabits the Bay of Naples. Ulysses. 



Born has described this shell to be five inches long, and half as 

 broad, with a strong solitary varix opposite the outer lip ; 

 whirls about eight, with thick convex angulated ribs, and their 

 interstices marked with elevated double striee ; aperture ovate- 

 oblong, plaited, and attenuating into an umbiticated, chan- 

 nelled, recurved beak; colour pale yellow. In the Museum 

 Leskianum the colour is said to be sub-ferrugineous, and the 

 throat somewhat like opal. Gmelin has erroneously quoted 

 Chemnitz's figure of M. lyratus^ jointly with those of this 

 species, for a variety of M. Lotorium, and has described 

 two other shells under the name of M. costatus, of which 

 one is probably nothing more than a variety of 31. cornutuSf 

 and the other is a fossil. The name was also before given by 

 Pennant to another species. 



LYRATUS, 30. Shell with strong distant transverse 

 ribs, and the beak flexuous and ascending- ; 

 lips thick, and the outer double and sinuated.
