Prate XIII. 
Species 71. (Mus. Cuming.) 
Trocuus NiGRopunctatus. Tvroch. testa subampliter 
eaxcavato-umbilicatd, abbreviato-conicd, cinereo-virente, 
nigro oblique flammatd ; anfractibus plano-convexis, 
gronis regularibus spiraliter confertissime gemmatis ; 
basi grano-liratd, interstitiis crispato-decussatis, liris 
nigro-punctatis, punctis conspicuis, distantibus. 
Tar piack-pottep Trocuus. Shell rather largely 
excavately umbilicated, shortly conical, ash-green, 
obliquely flamed with black; whorls flatly convex, 
spirally very closely gemmed with regular grains ; 
base grain-ridged, interstices crispately decussated, 
ridges dotted with black, dots conspicuous, distant. 
Hab. Natal. 
The surface of this species is grained with unusual re- 
gularity, and the base is very characteristically sprinkled 
at rather distant intervals with blue-black dots. Dr. Phi- 
lippi has figured this species, by mistake, both in his ‘Ab- 
bildungen’ and in Kiister’s Conch. Cab., for our 7. Han- 
leyanus, which is T. lineatus, Lamarck. 
Species 72. (Mus. Cuming.) 
TROCHUS VIVIDUS. 
breviato-conicd, vivide viridi, 
Troch. testé excavato-umbilicatd, ab- 
corallo-rubro  vivide 
flammatd ; anfractibus concavo-declivibus, regulariter 
spiraliter granatis, granis subamplis, obliquis, inter- | 
stitiis crispato-corrugatis, granis jucta suturas pli- 
cato-nodatis ; basi plano-concavd, grano-lirald, liris 
alternatim majoribus, virescente, punctis minutis rufis 
lentiginosd. 
BRIGHT Trocuus. Shell excavately umbilicated, 
shortly conical, bright green, brightly flamed coral- 
red; whorls concavely sloping, regularly spirally 
grained, grains rather large, oblique, interstices cris- 
pately wrinkled, grains next the sutures plicately 
noduled; hase flatly concave, grain-ridged, ridges 
alternately larger, greenish, freckled with minute red 
dots. 
THE 
Hab. ? 
A solid brightly coloured species, allied in general as- 
pect to 7. cariniferus, Beck. 
Species 73. (Mus. Hanley.) 
Trocnus cauuicoccus. rock. testd angusté excavato- 
umbilicald, acute depresso-conoided, virescente-olivaced, 
sordid purpureo-rufo grandimaculatd ; anfractibus 
plano-concavis, spiraliter conspicue papillari-granatis, 
ad marginem plicato-nodatis ; basi plano-concavd, re- 
gulariter grano-liratd, punctis lilacino-rufis pallide 
aspersd. 
HANDSOME-GRAINED Trocuus. Shell. narrowly 
excavately umbilicated, sharply depressly conoid, 
greenish-olive, large-spotted with dingy purple-red ; 
whorls flatly concave, spirally conspicuously papillary 
grained, plicately noduled at the margin; base flatly 
| THE 
coneave, regularly grain-ridged, faintly sprinkled 
with lilac-red dots. 
Hab. ? 
| Very largely papillary grained, and plicately noduled at 
the edge, the nodules taking the form of prickly radiations. 
Species 74. (Mus. Cuming.) 
| TROCHUS TABIDUS. 
presso-conoided, cinereo-albd ; anfractibus plano-decli- 
Troch. testa imperforald, acute de- 
| vibus, oblique irregulariter rugatis, versus apicem tu- 
berculatis ; basi plano-convexd, subobsoleté sulcatd, 
| columellé calloso-contortd. 
THE consuMpPTIVE Trocuus. Shell imperforate, sharply 
depressly conoid, ash-white; whorls flatly sloping, 
obliquely irregularly wrinkled, tubercled towards the 
apex ; base flatly convex, rather obsoletely grooved, 
columella callously twisted. 
Hab. Australia. 
| Partaking of the general character of 7. pyramis and 
| noduliferus. 
Species 75. (Mus. Cuming.) 
Trocuts oprsus. Troch. testd excavato-umbilicatd, obeso- 
conicd, albidd, virescente tinctd, versus basin olivaceo 
interrupts flammatd ; anfractibus conveaiusculis, obso- 
lete granulatis, ad marginem plicato-nodatis ; basi 
concavinsculd, obsolele granulatd, 
Tue stour Trocuus. Shell excavately umbilicated, 
stoutly conical, whitish, tinged with green, inter-
