TURBO.—Ptate VIII. 
yellowish, ridges here and there bright green, interior 
silver. 
Hab. New Holland; Dring. 
This beautiful new species is remarkable for the deli- 
cacy and singularity of its painting, the spiral rows of 
scales showing each a fine narrow bright green band upon 
a pale orange-yellow ground, faintly stained with brown. 
Species 36. (Mus. Cuming.) 
TurBo Cuumnitzianus. Turd. testd ovaté, imperforatd, 
anfractibus subangulatis, liris parvis, squamarum seriebus 
cingulatis, interstitiis minutissimé laminiferis ; albidd, 
strigis parvis fuscescentibus oblique undatd, intus ar- 
gented. 
CuEmMnNttz’s TurBo. Shell ovate, imperforated, whorls 
slightly angular, encircled with small ridges and 
rows of scales, interstices very minutely laminiferous ; 
whitish, obliquely waved with small, light brown 
streaks, interior silvered. 
Argyrostomus maris rubri, Chemnitz, Conch. Cab. vol. v. 
p- 199. pl. 180. f. 1788-9. 
Hab. Red Sea; Forshael, fide Cuming. 
This species does not appear to have been identified by 
any author since its publication in the Conchylien Cabinet 
in the year 1781. Chemmnitz’s admirable figure of it was 
referred to by Lamarck for the 7. radiatus, but it will be 
found to differ very materially from that species. It is a 
larger shell, not imperforated, and of lighter growth, whilst 
the last whorl is more ventricose and has a somewhat an- 
gular appearance from its being encircled with three ridges 
of scales. The colouring is peculiar; the ground is a soft 
greyish cream colour, the pattern consisting of delicate 
brown zigzag streaks darting from the sutures. 
The locality which Mr. Cuming has on good authority 
with this interesting shell, agrees precisely with that 
recorded by Chemnitz. 
Species 37. (Mus. Saul.) 
TuRBo sETosus. urd. testd ovati, imperforatd, anfractu 
ultimo ventricosissimo, anfractibus undique spiraliter 
costatis, costis rotundis, regularibus, interstituis eaca- 
vatis, apertura ampli, basi effusd, fauce sulcata ; albidé, 
viridi et fusco-viridi tessellata, intus argented ; oper- 
culo testaceo, crasso. 
THE RouGH TuRBO. Shell ovate, imperforated, last whorl 
very ventricose; whorls spirally ribbed throughout, 
ribs round, regular, interstices excavated, aperture 
large, effused at the base, interior grooved; whitish, 
tessellated with green and brown-green, interior sil- 
vered ; operculum testaceous, thick. 
GMELIN, Syst. Nat. p. 3594. 
Hab. Lord Hood’s Island, Pacific Ocean (on the reefs) ; 
Cuming. 
This species is amply distinguished from any other of 
the genus by its deeply carved spiral ribs, whilst the aper- 
ture is large and peculiarly effused at the base.
