FUSUS regular is.

Syn, Murex regularis of Tab. 187. f. 2. Murex 
antiquus, JBrander f. 74. sed non Linn . 
TThe small specimens of this species figured formerly, 
were not suspected to belong to Brander’s M. antiquus, 
hut a series presented by the Rev. T. Cooke, several of 
which agree exactly with Brander’s figure and descrip- 
tion, prove that they are the same. 
The three species figured upon the same plate, (tab. 
187.) and called Murices, certainly belong to the Genus 
Fusus, as it is at present established by Lamarck; they 
are all remarkable for the square shape of the elevated 
Ikies that cross them, and are not met with abroad. 
FUSUS complanatus. 
TAB. CCCCXXI1I. —figs. 2 and 3. 
Spec. Char. Ovato-fusiform, pointed, costa- 
ted, and transversely striated ; superior 
edges of the whorls elevated and pressed 
upon the spire ; striae contiguous ; columel- 
la curved. 
There are two varieties of this Fusus, one of them has 
the costae much more prominent than the other ; in both 
the obtuse, slightly elevated ridges between the striae 
give the surfaces a uniformity of character by which the 
species is well distinguished. The beak is shorter than 
the spire, and a little expanded ; there is no appearance 
of a fold upon the columella, by which it is distinguished 
from several nearly allied French species. 
Both varieties were found plentifully at Highgate, 
while the road through the Hill was in progress. 
Fig. 3, represents the costated variety.
