transversely on both margins. Very large ones inhabit the seas of 
Europe* * * § . 
The varices are sometimes numerous, compressed, and almost 
membranous, constituting the Trophona, Montf. \ 
At other times, they are compressed, very salient, and but few in 
number^. 
M. de Lamarck separates from all the Murices of Brugiere, the 
Ranella, Lam., 
Characterized by opposing varices, so that the shell is bordered 
with them on both sides. Their canal is short, and their surface 
studded with mere tubercles ; margins of the aperture plicated^. 
I'he Apolles, Montf., are merely umbilicated Ranellte ||. The 
, Fusus, Brug. 
Comprises all shells with a salient and straight canal, which are 
destitute of varices. 
AVdien the spire projects, the columella is without plicae, and the 
margin is entire, they are the Fusus properly so called, Lam., which 
Montfort again su!)divides ; when they have no umbilicus, they are 
his Fusus^. I’lie shortest and most ventricose gradually a])proach 
the form of the Buccina** * * §§ . Wiien provided Avitli an umbilicus they 
are his Lalhira ff . 
The Strutlnolarice are distinguished from the true Fusi by a bor- 
der Avhich surrounds their aperture, and Avhich covers the columella. 
The margin of the adult is inflated, which connects them with 
MurexjJ. 
^Fhen the spii’eis salient, the columella without plicae, and there is 
a small indentation or well marked emargination of the margin near 
the spine, they are the Fleur otoma, Lam.§§
