burying itself amongst weed and ooze on sandy and muddy flats 

 beyond tide-mark. 



Y. JUNONIA, Chemn. PL 26, fig. 67. 



Pale yellowish or whitish, with numerous rather large rounded 

 square chestnut-colored spots arranged in revolving series ; 

 interior flesh-white. Length, 3'5-4*5 inches. 



East and West Coasts of Florida. 



It is an inhabitant of deep water, and is somewhat rarely 

 obtained and highly prized by collectors. Specimens have been 

 sold as high as two hundred dollars, but of late years the value 

 has greatly decreased in consequence of increased supply. 



Y. DUBIA, Brod. PL 27, figs. 77, 81. 



The spire is proportionally longer, the .spots more sharply 

 square than in V. Junonia, the longitudinal ribs, which in that 

 species are barely visible upon the first whorl below the embryo- 

 nal apex, show traces of their existence as far as or even 

 including the body-whorl. V. Junonia is spirally sculptured 

 towards the base of the body-whorl, whilst in this species the 

 sculpture covers the entire whorl. Length, 3*6 inches. 



Caribbean Sea, off tJie Southern 



and Western Coasts of Florida. 



This shell was first figured as Fusus tessellatus by Schubert 

 and Wagner, and subsequently described by Broderip as V. 

 dubia (fig. 81), but the shell was only known in an immature and 

 faded condition until Dr. Dohm in 1879 gave a full description 

 with figures of what he supposes to be the adult shells. My 

 impression is that it is merely an elongated variety of V. Junonia, 

 but the question of identity can only be settled satisfactorily 

 when a larger mass of material shall be at the disposal of 

 naturalists, than is now available. 



Y. KAUPII, Dunker. PL 26, fig. 69. 



All the whorls except the embryonal apex are slightly plicate 

 below the sutures ; last whorl obtusely angular ; pale yellowish 

 red, marbled irregularly with a darker tint. Length, 2*25 inches.

Probably not mature ; the type is the only specimen known.
