CycLopHorus TUBA. Cyel. testé subampliter profundé

Tuer TRUMPET CycLopHorus. Shell largely deeply um- 
bilicated, transversely ovate, rather thin, whitish be- 
neath a fulvous epidermis, reticulately freckled and 
clouded with reddish-brown, filleted with a row of 
small oblique blotches next the sutures, a broad 
freckled band below the periphery; whorls rounded, 
the last very elegantly inflated towards the aperture ; 
lip broadly expandedly reflected.

Cyclophorus tuba, Pfeiffer. 
Cyclophorus Sumatrensis, Pfeiffer. 
Hab. Malacca, Sumatra. 
This very elegantly convoluted species is characterized 
by a peculiarly expanded growth of the shell on arriving 
at maturity, the aperture opening out, with its broadly 
dilated lip, like a French horn. C. Swmatrensis, Pfeiffer, 
of which the type-specimen is represented at Fig. 9 a, is 
a variety in which the upper half of the whorls is devoid 
of the freckled painting. The sutural blotches and the 
band below the periphery are very neatly defined.

CyctopHorus Prarsoni. Oyel. testd modicé umbilicatd, 
orbiculari-turbinatd, sub epidermide tenui fulvescente- 
alba, ustulato-castaneo tinctd et lineata, versus apicem 
fulguratad, ad peripheriam fascid perangustd, albidd, 
fascia nigricante paulo latiore umbrata ; spird eleva- 
tiusculd, anfractibus declivi-rotundatis, spiraliter densé 
granoso-striatis, ultimo ad peripheriam interdum ob- 
scuré carinato; apertura feré circulari, labro eleganter 
reflexo, vivide rufo-aurantio. 
Pearson’s CycLopHorus. Shell moderately umbilicated, 
orbicularly turbinated, yellowish-white beneath a thin 
epidermis, stained and lineated with burnt chestnut, 
a very narrow white band at the periphery, shaded 
by a rather broader blackish band; spire somewhat | 
raised, whorls slopingly rounded, spirally densely 
grain-striated, the last sometimes obscurely keeled 
at the periphery; aperture almost circular, lip ele- 
gantly reflected, bright rufous-orange.

Cyclophorus Pearsoni, Pfeiffer. 
Hab. Khasya Hills, India; Dr. Hooker. 
The specimen of this very charming species here. figured, 
which is in finer condition, enveloped by a delicate epi- 
dermis, and has a deeper-coloured lip than any other 
known to me, was collected by Dr. Hooker on the Khasya 
Hills. 
Species 11. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus Pretrreri. Cycl. testd modicé umbilicatd, 
subgloboso-turbinatd, tenuiusculd in medio subobsolete 
carino-angulatd, albidi, fulvescente-fusco supra peri- 
pheriam tenué lentiginosd, infra saturate latifasciata ; 
spira elevatiusculd, anfractibus rotundatis, spiraliter 
confertim leviter yranoso-striatis, ultimo versus aper- 
turam rotundato-inflato, circa umbilicum subremote 
lineari-fasciato; labro latissimé plano-expanso, rufo- 
aurantio. 
Preirrer’s CycLopHorvs. Shell moderately umbilicated, 
somewhat globosely turbinated, rather obsoletely 
keel-angled round the middle, rather thin, whitish, 
lightly freckled with fulvous-brown above the peri- 
phery, broadly banded, of a darker tone below it ; 
spire somewhat raised, whorls rounded, spirally 
closely lightly grain-striated, last whorl rotundately 
inflated towards the aperture, rather distantly line- 
arly banded around the umbilicus, lip very broadly 
flatly expanded, rufous-orange. 
Hab. Island of Pulo-Penang. 
More globosely convoluted than C. tuba or speciosa, 
with the whorls rounded and the spire more elevated. 
The lip is equally largely expanded, but instead of curling 
gracefully over, it is expanded in a sharply angular flat- 
tened manner. The specimen figured was named by Dr. 
Pfeiffer in manuscript C. Cantorz, but it will be found, on 
reference to our figure of Mr. Benson’s type of that spe- 
cies, to be materially distinct. 
June, 1861.
