LEUCOZONIA. 95 



names ; the numerous specimens before me, representing localities 

 from Florida, Central America, West Indies and Brazil, enable 

 me to place these in the synonymy. Figs. 166-168 represent 

 L. angularis, Reeve; Fig. 169 is L. Knorrii, Desh., from Hon- 

 duras and Brazil; Fig. 170 is L. Braziliana, d'Orb., also from 

 Brazil, and Fig. Ill represents the animal thereof; Fig. 173 is 

 L. rudis, Reeve. 



L. inculta, Gould, described without figure or locality is very 

 probably a synonym. L. nassa, Gmel, is the oldest name for the 

 species, but he included L. leucozonalis in his species, and as 

 the subsequent name given by Lamarck has become universally 

 current, it seems advisable to adopt it. 



L. TRISERIALIS, Lam. PI. 70, figs. 174-177. 



Chestnut-brown, encircled with three rows of revolving, whitish 

 nodules ; aperture and columella white. Length 1-1*5 inches. 

 Isle St. Vincent ; W. Africa. Menke / BaJiia, Brazil. 



The latter locality is for L. dubia, Petit (fig. 174). which 

 appears to me to be a somewhat depauperate variety of triserialis. 

 Another variety is Turbinella Hidalgoi, Crosse (fig. 177), which 

 develops three instead of the two lower rows of tubercles. Its 

 habitat is unknown. 

 L. MULTANGULA, Phil. PI. 70, fig. 187. 



Yellowish-white, with brown strigations between the longitu- 

 dinal ribs. Length, 1-12 inches. 



Yucatan. 



There is but little doubt that this species, described as a 

 Fusus, really belongs to the Peristerniinae, as the columella is 

 said to be plicate at the base, and the form is not unlike speci- 

 mens of L. triserialis. It may equal that species, possibly, with 

 longitudinal ribs, developed at the expense of revolving ones. 

 It is an immature individual. 



L. OCELLATA, Gmelin. PI. 70, figs. 178, 179. 



Chestnut or chocolate, the raised portions white ; aperture 



white. Length, 1-1-25 inches. 



West Indies. 



There is considerable variation in the form of this well-known 

 species, the spire being sometimes drawn out like the elate forms 

 of L. cingulifera, Lam.
