Svn. Fusus ficulneus. Lamarck env. de Paris , 62. 
var. a, smooth, costse subspinose above the mid- 
dle, and also near the upper edge of the 
volutions. 
var. /3, covered with elevated striae, costae sub- 
spinose near the upper edge of the volution 
only. 
var. y, striae few, costae obscure. 
Syn. Murex turgidus. Brander , 51. 
In all the varieties the upper edge of each whorl 
depressed, and upon the edge of the flat part is a row 
of more or less acute tubercles, which are sometimes 
even double ; below these the surface is concave and 
the costae rise : in var. a, the costae are elevated at the 
edge of the concave space into more or less obtuse, 
short, and rather flat spines, and the lower part of the 
whorl and beak are striated : in var. /3, the costae are 
highly elevated for a considerable length without any 
appearance of spines or even tubercles ; they are also 
crossed by numerous strong elevated lines, which are 
thickened as they pass over them : the third variety has 
similar striae but not so numerous, and the costae in it 
are often very obscure ; the spire is acute in all, and the 
proportions the same ; the width is about three-fourths 
the length.
