GENERIC CHaracTEer.—See Zool. Illustr. 1 Series, Pl. 23. 
Speciric CHARACTER. 
Shell smooth, blackish brown, with very minute punctured trans- 
verse strive; spire attenuated, longer than the aperture ; pillar 
4-plaited.

WE are acquainted with two shells, perfectly distinct as 
species, yet sufficiently alike to render Lamarck’s descrip- 
tion of his M. melaniana applicable to both. In this un- 
certainty, we at first intended to distinguish this by the 
name of carbonaria, and to consider the other as Lamarck’s 
melaniana, but further consideration induces us to alter 
this arrangement; the second species we propose to illus- 
trate in an early number. Our figure was taken from a 
full-sized specimen, received from Australia, and now in 
the Manchester Museum. 
rE 
MITRA tessellata. 
Shell ovate, smooth, with remote transverse punctured striz ; whit- 
ish, cancellated by transverse and longitudinal fulvous lines ; 
inner lip brown at the base ; outer lip smooth.

(Ap. 1824.) 
We have already given a full account of this very rare 
shell; a repetition of which is rendered unnecessary by the 
publication of the figures. The specimen from which these 
were taken, was then in the possession of Mrs. Mawe, whose 
kindness and liberality, in forwarding our scientific pur- 
suits, has been, for very many years, constant and in- 
variable. We know not its country, nor have we ever seen 
a second example. 
Mr. Grey has recently given an additional interest to this 
group, by publishing an account of the structure of the 
animal.
