anfractibus rotundatis, levibus, concentricé striatis ; 
ceruleo-viridi, intus argented ; operculo testaceo, crasso.

cular, whorls rounded, smooth, concentrically striated ; 
blueish-green, interior silvered ; operculum testaceous, 
thick.

Turbo helicinus, Born. 
Hab. New Zealand. 
This shell has very much the form of a Helix, as indi- 
cated by the name above quoted from Born. It may be 
as well to mention that the specimen here figured is of 
rather small size. 
Species 14. (Fig. a and 6, Mus. Cuming.) 
Turso saxosus. Turb. testd imperforatd, ovata, spire 
suturis subprofundé impressis; anfractibus superné 
concavo-declivibus, medio angulatis, transversim obscure 
liratis, tuberculis juxta suturas coronatis, infra nunc 
muticis, nunc tuberculis bi-triseriatim armatis, laminis 
subtilibus, longitudinaliter obliquis, peculiariter exsculp- 
tis; viridi albimaculatd, intus argented ; operculo 
testaceo, crasso. 
THE stony Turso. Shell imperforated, ovate, sutures 
of the spire rather deeply impressed ; whorls con- 
cavely slanting round the upper part, angulated in 
the middle, transversely obscurely ridged, coronated 
with tubercles next the sutures, beneath either free 
or armed with two or three tubercles, peculiarly 
engraved with fine longitudinally oblique lamine ; 
green, blotched with white, interior silvered; oper- 
culum testaceous, thick. 
Hab. West Columbia; Cuming. 
Having observed this species in a private collection, 
under the name saxosus in manuscript, I adopt it, though 
not a very appropriate one, lest it may have been pub- 
lished and escaped my observation. The rows of tubercles 
are extremely variable, being even more prominently de- 
veloped in specimens of smaller growth than is here 
represented. 
Species 15. (Mus. Cuming.) 
TuRBo sarmaticus. Turd. testd imperforatd, suborbicu- 
lari, ventricosd, spird brevissimad, anfractibus levibus, 
superne depressiusculis, infra triseriatim nodatis ; au- 
rantio-flavicante nigro et fusco-rubro radiata et fasciata, 
intus margaritaced, prope marginem intense nigra ; 
operculo testaceo, cristato. 
THE RED-BROWN TuRBOo. Shell imperforated, nearly 
orbicular, ventricose, spire very short, whorls smooth, 
rather depressed round the upper part, encircled 
with three rows of nodules beneath; orange-yellow, 
radiated and banded with black and red-brown, 
pearly within, intensely black near the edge; oper- 
culum testaceous, tufted.

Hab. Cape of Good Hope. 
The operculum of this well-known species is composed 
of a dense tuft of erect club-shaped particles. 
Species 16. (Mus. Cuming.) 
Turso maqniricus. Turd. testd imperforatd ovata, ven- 
tricosd, spird brevi ; anfractibus levibus, obscuré sub- 
tilissimé liratis, superné infra suturas leviter canalicu- 
latis ; albidd aut viridescente, fusco nigroque profuse 
variegaté et maculatd, intus margaritaced ; operculo 
testaceo, crasso. 
THE MAGNIFICENT TuRBO. Shell imperforated, ovate, 
ventricose, spire short; whorls smooth, obscurely 
very finely ridged, slightly channelled round the upper 
part beneath the sutures; whitish or pale green, pro- 
fusely blotched and variegated with black and brown, 
interior pearly ; operculum thick, solid. 
Jonas, Philippi, Abbild. und Besch. Conch. Turbo. 
Hab. Bay of Sechura, Peru (dredged from a depth of 
fourteen fathoms); Cuming. 
A new species, described by Dr. Jonas of Hamburgh, 
of which this is the only specimen I have seen; it is 
certainly a very characteristic one, and claims especial 
attention.
