TURBINELLA.—Puate V. 
Species 28. (Mus. Cuming.) 
TURBINELLA IMPERIALIS. Turd. testd ovaté, crassé, 
superne ventricosd, spird brevi ; anfractibus transversim 
liratis, liris acutis distantibus, supernée subangulatis, ad 
angulum tuberculis grandibus squamatis, erectis, sub- 
recurvis conspicue coronatis, tuberculorum seriebus 
duabus prope basin quarum superiore majore ; albidd, 
fusco ustulatd, tuberculis nigricantibus, epidermide 
jibrosd indutd ; columelld purpureo-fusco tincta. 
THE IMPERIAL TURBINELLA. Shell ovate, thick, ven- 
tricose round the upper part, spire short, whorls 
transversely ridged, ridges sharp and distant, suban- 
eulated round the upper part, conspicuously coro- 
nated at the angle with large erect slightly recurved 
squamate tubercles, with two rows of tubercles near 
the base, of which the upper is the larger; whitish, 
scorched with brown, tubercles blackish, interior 
white, columella stained with rich purple brown.

This species is still confounded in the British Museum 
with the 7. cornigera, although well figured m the ‘ Con- 
chologia Systematica’, and described in detail by M. 
Deshayes in his edition of the ‘Animaux sans vertébres’; 
it is scarcely necessary to enter into any comparison 
as the difference may be detected at a glance. 
It is much to be regretted that the shells in our national 
museum are so imperfectly named, of this genus in parti- 
cular; the collection, instead of manifesting a critical 
knowledge of species, enabling us to consult it as an 
authority, is full of misnomers, and (as this work testifies) 
of little service for the purposes of study

Tur arMED TuRBINELLA. Shell oblong-ovate, - thick, 
ponderous, spire somewhat exserted ; whorls irregu- 
larly sharply ridged and striated in the middle, 
concavely impressed round the upper part, coronated 
with strong squamate tubercles, last whorl encircled 
by a double row of tubercles above and below ; colu-

One distinguishing feature of this species is its peculiar 
blue-stained colouring. 
Species 30. (Mus. Cuming.) 
TURBINELLA caprreLtuM. Turb. oblongo-ovatd, longi- 
tudinaliter varicoso-costatd, anfractibus superné con- 
cavo-angulatis, deinde liris squamatis, suberectis, inter- 
stitiis profunde excavatis, cingulatis, squamis ad angu- 
lum prominentibus erectis ; albidd. 
THs CHAPITER TURBINELLA. Shell oblong-ovate, longi- 
tudinally varicosely ribbed, whorls concavely angulated 
round the upper part, then encircled with partially 
erect squamate ridges, the interstices between which 
are deeply excavated, scales upon the angle erect and 
prominent ; whitish.

There is no doubt but that M. Kiener is correct in 
uniting the Z. capitellum and mitis of Lamarck; they are 
merely different states of the same species. 
Species 31. (Mus. Cuming.) 
TURBINELLA VEXILLULUM. Turd. testd ovatd, utrinque 
acute attenuatd, anfractibus liris acutis confertis, alter- 
natim majoribus undique cingulatis, medio angulatis, 
ad angulum tuberculis mucronatis armatis ; nigricante- 
caruled, liris alternatim roseis et albis ; intus cerules- 
cente-albi. 
THE LITTLE FLAG TURBINELLA. Shell ovate, sharply 
attenuated at each end, whorls encircled throughout 
with sharp ridges alternately larger, angled in the 
middle, armed at the angle with pointed tubercles ; 
very dark blue, ridges alternately pmk and white, 
blueish white within.

An extremely pretty species, offering so formal and gay 
a display of colour as to look artificially painted.
