FASCIOLARIA. 



murex tulipa. — Linn. 



Martini, 4, tab. 136, fig. 1286, 1287. 



This genus is divided from the G. Murex of Linnaeus 

 in consequence of never having any varices, though it 

 has a canal at the base. Bruguiere had separated these 

 shells, but confounded them with the G. Fusus, from 

 which they differ in having plaits on the columella. 

 The plaited pillar brings them nearer to the G. Turbi- 

 nella, but in the latter, the position of the plaits is 

 transverse, while in this it is spirally oblique. The 

 shell is fusiform, whorls sometimes nodulous, canalicu- 

 lated at the base; two or three plaits on the columella, 

 oblique and spiral; it has an epidermis, and horny oper- 

 culum.
