TURBINELLA. 
PLATE X. 
Species 49. (Mus, Cuming.) 
TURBINELLA ANGULARIS. Turd. testd ovatd, utringue 
attenuatd, anfractibus transversim striatis et subtiliter 
liratis, medio ventricosis et acute angulatis, ad angulum 
compresso-tuberculatis ; castaneo-fuscd, liris tuberculos 
super albidis. 
THE ANGULAR TURBINELLA. Shell ovate, attenuated at 
both ends, whorls transversely striated and finely 
ridged, ventricose and sharply angled in the middle, 
compressly tubercled at the angle; chesnut-brown, 
ridges across the tubercles whitish.

Hab. 
This species may be traced into the 7. cingulifera, but 
is constantly distinguished by its sharp angular growth 
and compressed tubercles. 
Species 50. (Mus. Cuming.) 
TURBINELLA BREVIcAUDATA. Turb. testd elongato-tur- 
binatd, canali brevi, spird elongaté, anfractibus rotun- 
datis, fortiter plicato-nodatis, superné juata suturas 
peculiariter longitudinaliter plicato-striatis, liris con- 
spicuis regularibus cingulatis, interstitiis excavatis, strid 
unicd elevata interveniente ; albidd, fusco tinctd, liris 
striisque vivide castaneis. 
THE SHORT-TAILED TURBINELLA. Shell elongately tur- 
binated somewhat fusiform, canal short, spire elon- 
gated, whorls rounded, strongly plicately noduled, 
peculiarly longitudinally plicately striated round the 
upper part, next the sutures, encircled with conspi- 
cuous regular ridges, the interstices between which 
are excavated and have a single raised stria inter- 
vening; whitish, stained with brown, ridges and 
strie rich chesnut-brown. 
Hab. ? 
A very characteristic sharply corded species, having 
somewhat the form of the 7. lineata but not the colour.

Species 51. (Mus. Cuming.) 
TURBINELLA RUDIS.  Twurb. testé oblongo-ovatd, soli- 
diusculd, transversim rude lirata et striata, anfractibus 
superne concavis, medio compresso-nodatis, nodis basin 
versus evanidis; albd, epidermide crassé castaneo- 
nigricante induta. 
THE RUDE TuRBINELLA. Shell oblong-ovate, rather solid, 
transversely rudely ridged and striated, whorls concave 
round the upper part, compressly noduled in the 
middle, nodules gradually disappearing towards the 
base; whitish, covered with a thick chesnut-black 
epidermis. 
2 
Hab. 
Approaching the 7. twberculata in form, but readily 
distinguished from that species. 
Species 52. (Mus. Metcalfe.) 
TuRBINELLA Kwnorriut. Turd. elongato-turbinatd, sub- 
fusiformi, transversim striaté, anfractibus superné 
concavo-depressis, medio conveais, nodorum serie unicd 
cingulatis, aperture fauce liraté ; rufo-castaned, intus 
albida. 
Kworr’s ‘TuRBINELLA. Shell elongately turbinated, 
somewhat fusiform, transversely striated, whorls con- 
cavely depressed round the upper part, convex in the 
middle, with a single row of rounded nodules, interior 
of the aperture ridged; reddish-chesnut, interior 
white, 
Hab. Honduras ; Dyson. 
This species like the Z. angularis just spoken of may 
also be traced into 7. cingulifera, from which it is distin- 
guished by its more elongated growth and series of rounded 
nodules. 
Species 53. (Mus. Metcalfe.) 
TURBINELLA GRACILIS. Turd. testa subelongato-fusiformi, 
anfractibus superné concavis, longitudinaliter oblique 
rude plicato-costatis, liris obtusis wregularibus cin- 
gulatis ; rufescente-fuscd. 
THE SLENDER TURBINELLA. Shell somewhat elongately 
fusiform, whorls concave round the upper part, longi- 
tudinally obliquely rudely plicately ribbed, encircled 
with irregular obtuse ridges ; reddish-brown. 
Hab. ? 
Though closely allied to the 7. castanea and acuminata 
it is clearly irreferable to either of those species 
August, 1847.
