all systems; namely, such a knowledge of the individuals, as will 
enable the student to assign to each ‘‘a local habitation and a 
name,” 
I shall now proceed to describe several beautiful shells; dena 
of uncommon rarity, and apparently unknown to modern writers : 
the four first belong to the genus Voluta, as it is now restricted ; 
and the remainder to Mitra, a genus towhich I have long paid much 
attention, with the ultimate hope of illustrating it by a distinct 
monograph.

DESCRIPTION. 
_ The shell in its habit, approaches V, vespertilio: its total length 
is about two inches, of which the spire occupies not more than half 
an inch: its form is oval, and its surface without sculpture: the 
basal volution, and the two first whorls of the Spire, are crowned 
by a row of short thin vaulted spines, rather acute, and resembling 
those on V. diadema, (Ex. Conch, Fas. 1.) The remaining three 
spiral whorls are perfectly smooth, the middle one being by much 
the largest, and the whole forming a thick and somewhat obtuse 
cone. The base is deeply emarginate, and the plaits on the colu- 
mella, (which are four in number) are very thick, The ground 
colour of the specimens before me is nearly white, with broad
