CYCLOPHORUS. 
Puate IX. 
Species 35. (Fig. a, 6, Mus. Cuming; Fig. 4, c, Mus. 
Benson.) 
CycLoPHoRUS FULGURaATUS. Cycl. testé modicé umbili- 
cata, subgloboso-turbinatd, albidd, strigis castaneis ful- 
guratis transversim lentiginosd, infra peripheriam con- 
spicue fasciatd, deinde fulguratd, circa umbilicum

THE LIGHTNING-MARKED CycLopHorus. Shell mo- 
derately umbilicated, rather globosely turbinated, 
whitish, transversely freckled with zigzag chestnut 
streaks, conspicuously banded below the periphery, 
then zigzag-streaked, unspotted around the umbi- 
licus, whorls rounded, rather inflated, everywhere

63. 
Cyclophorus fulguratus, Pfeiffer. 
Hab. Burmah. 
This very interesting species has been collected in the 
British provinces of Burmah, of various sizes. The spe- 
cimen represented at Fig. 35 4, c, is that referred to by 
Mr. Benson in the ‘ Annals and Magazine of Natural His- 
tory, 1856, vol. xvii. p. 232, with a “shining-orange 
peristome,” collected by Mr. Theobald at Rangoon. 
Species 36. (Fig. a, 6, Mus. Benson.) 
CycLopHorus Aurora. Cycl. testé modicé umbilicaté, 
globoso-turbinatd, tumidiusculd, albidi, fumeo-castaneo 
purpureo-tincto fasciatim nebulata et lentiginosd, ver- 
sus apicem livido-purpurascente, castaneo obscuré ful- 
guratd, infra peripheriam fasciatd, deinde lineari- 
punctatd ; anfractibus amplis, subinflatis, undique 
carino-liratis, liris obtusis, distantibus, interstitiis ele- 
vato-striatis ; apertura subcirculari, labro modicé re- 
flexo, aurantio vel aurantio-rufo. 
Tue AvrorA CycLopHorus. Shell moderately umbili- 
cated, globosely turbinated, rather swollen, whitish, 
clouded and freckled in a banded manner with 
purple-tinged smoky-chestnut, livid-purple towards 
the apex, obscurely zigzag-marked with chestnut, 
banded below the periphery, then linearly dotted, 
whorls large, rather inflated, keel-ridged throughout, 
ridges obtuse, distant, interstices elevately striated ; 
aperture nearly circular, lip moderately reflected, 
orange or orange-red. 
Cyclostoma Aurora, Benson, Ann. and Mag. Nat. Hist., 
Second Series, 1851, vol. viii. p. 186. 
Cyclophorus Aurora, Pfeiffer. 
Hab. Darjiling, Sikkim-Himalaya. 
Doubts were entertained of the value of this species 
originally, and it was figured by Pfeiffer in Kiister, Conch. 
Cab. pl. 50. f. 11 to 18, as a variety of his C. stenom- 
phalus. The shell represented at Fig. 36 a, 6, is one of a 
very characteristic series of specimens which Mr. Benson 
has since received from Sikkim-Himalaya, and all doubt 
on the subject is now removed. 
Species 37. (Fig. a, 6, Mus. Benson.) 
CycLoPHORUS CRYPTOMPHALUS. Cycl. testé modicé ex- 
cavato-umbilicatd, subgloboso-turbinatd, solidiusculd, 
albidd, fulvo-castaneo fulguraté et fasciatim nebulata, 
ad peripheriam immaculatd, deinde latifasciatd, circa 
umbtlicum tmmaculatd, anfractibus rotundatis, obscure 
granoso-striatis, juata suturas subdepressis ; apertura 
subcirculari, labro incrassutim reflexo, super umbilicum 
lingulato. 
THE HID-UMBILICUS CycLoPHoRUs. Shell moderately 
excavately umbilicated, somewhat globosely turbi- 
nated, rather solid, whitish, zigzag-marked and 
clouded in a banded manner with fulvous-chestnut, 
unspotted at the periphery, then broadly banded, 
unspotted round the umbilicus, whorls rounded, ob- 
scurely grain-striated, a little depressed next the su- 
ture; aperture nearly circular, lip thickly reflected, 
lingulate over the umbilicus.

vol. xix. p. 206. 
Hab. Ava, Burmah; Oldham. 
This species is founded on the single specimen repre- 
sented in the accompanying Plate, collected in the above- 
named locality by Mr. Oldham, Chief of the Geological 
Survey of India. It is rather damaged, but retains all 
the properties of the species. I cannot refer it to any 
other known Cyclophorus.
