CONUS. Linn. 
Gen. Cuan. Univalve, convoluted, inversely co- 
nical; spire short, composed of the upper 
edges of the whorls; aperture longitudinal, 
narrow, toothless, with parallel sides. 
"Pur form of most of the species of this Genus is an 
elongated cone, from whose base proceeds the spire, 
itself more or less conical, and either simple or coronated, 
generally much shorter than the remainder of the shell, 
although sometimes quite as long; the aperture is 
nearly equal in width through its whole length, but 
rendered more freely open at the ends by a kind of 
truncation at the base, and a deep sinus at the upper 
part of the right lip; the left lip is hardly visible, 
except at the base of the columella, where it forms a 
small plait. The surface is often variously ornamented 
by a beautiful variety of colours, strie, punctums, &e. 
The animal has two antenne, and a small operculum, 
and the shell is enclosed in a membranous epidermis. 
The recent Cones are inhabitants of tropical seas ; they 
are very handsome, and highly valued. Montfort has 
separated those with coronated spires, to form his genus 
Rhombus, a division which appears to be too minute; 
some of the other abstractions he has made may prove 
more useful.

CONUS Dormitor.—TAB. CCCI. 
Spec. Cuar. Short fusiform, transversely striated, 
-strize elevated, the intermediate spaces neatly 
crenulated. 
Syn. Conus dormitor, Brander, 24. 
Ta length of the spire is about equal to the greatest 
width of the shell, the aperture is rather longer, but 
. these proportions are liable to slight variation as shewn 
in figure 3; the elevated strie are rather numerous and 
sometimes placed in pairs, the crenulations between 
them are conformable to the lines of growth; the right 
lip is semicircular. 
I have been favoured with specimens of this Cone 
found at Muddiford, by Lady Burgoyne; I have also 
received it from Barton, through the kindness of Miss 
Dent, and several other Friends. It occurs frequently 
in a high state of preservation. 
Fig. 1 exhibits a young shell with a peculiar smooth 
band; I conceive however that it is only a variety. Fig. 
2, gives the general appearance, the middle figure is
