PARTULA. 
Plate II. 
Species 6. (Pig. a, b, Mus. Cuming.) 
Partula radiolata. Part, testa, oblongd, tenuiculd, 
unibilicata, basin versus oblique producla, anfractibus 
quinque, convexis, lineis impressis spiralibus subdistan- 
tibus cingulatis, columella late reflexa, plano-appressa,

The delicately rayed Paetula. Shell ohlong, 
rather thin, umbilicated, obliquely produced towards 
the base, whorls five in number, convex, encircled 
with rather distant spiral impressed lines, columella 
broadly reflected, flatly appressed, aperture obliquely 
ovate, lip rather thin, broadly reflected ; semitrans-

Hah. Island of Guam, Ladrones (on bushes) ; Cuming. 
An extremely delicate species, of a light straw-colour, or 
pale cinnamon-red, profusely obliquely marked with fine 
opake-white lines. 
Species 7. (Mus. Cuming.) 
Paetula lineata. Part, testa acuminato-oblongd, umbi- 
licatd, tenuiculd, anfractibus sex, spiraliter tenuissime 
impresso-striatis ; fulvescente, subpellitci.dd,f asciis dua- 
bus caslaneis distantibus cingulatd. 
The lineated Paetula. Shell acuminately oblong, um- 
bilicatcd, rather thin, whorls six in number, spirally 
very finely impressly striated ; light fulvous, subtrans- 
parent, encircled with two distant chestnut bands.

Hah. Friendly Islands. 
The lower of the two widely separated chestnut bands 
which encircle this species is only seen on the last whorl. 
Species 8. (Fig. 8 a, and 10, Mus. Cuming.) 
Partula amabilis. Part, testa pyramidali-oblongd, si- 
nistrorsd, subturritd, vix unibilicata, anfractibus sex, 
convexis, oblique tenuistriatis, ad suturas obscure sub- 
tilissime crenulatis ; fulvescente, castaneo conspicue 
latifasciata, interdum aurantio-fulvescente, apicem ver- 
April, 
sus eximie rosed, apertures labro interdum livido-pur- 
purascente. 
The lovely Paetula. Shell pyramidally oblong, sinis- 
tral, somewhat turreted, scarcely umbilicated, whorls 
six in number, convex, obliquely finely striated, ob- 
scurely very finely crenulated at the sutures ; fulvous, 
conspicuously broadly banded with chestnut, some- 
times orange-fulvous, tinged with rose towards the 
apex, lip sometimes livid purple.

Hab. Island of Annaa ; Captain Bohr. 
The fine spiral impressed lines which characterize most 
of the species are absent in this. 
Species 9. (Mus. Cuming.) 
Paetula densilineata. Part, testa acuminato-conicd, 
tenuiculd, umbilicata, spirce suturis impressis, anfrac- 
tibus superne subplanulatis et tenuimarginatis, inferne 
rotundatis aut leviter angulatis, columella plano-rejlexd, 
obsolete plicatd, aperturd ovatd, labro parum rejtexo ; 
albicanle, lineis obliquis ferrugineis cinereisque densis- 
sime pietd. 
The thickly-lineated Partula". Shell acuminately 
conical, rather thin, umbilicated, sutures of the spire 
impressed, whorls rather flattened and finely margined 
at the upper part, rounded and slightly angled at the 
lower, columella flatly reflected, obsoletely plicate, 
aperture ovate, lip but little reflected ; whitish, very 
thickly painted with oblique rust and ash lines. 
Hab. ? 
The lip of this shell, the only example of the species 
known to me, is scarcely mature. The linear painting is 
discontinued before reaching the umbilicus. 
Species 10. (Fig. 8 b, Mus. Cuming.) 
Paetula isabellina. Part, testa oblongd, crassd, um- 
bilicatd, anfractibus quinque, convexis, oblique striatis, 
apicem, versus, sub lente, tenuissime spiraliter impresso- 
lineatis, columella incrassatd, plicalo-gibbd, callositate 
superne manild, aperturd oblique producla, labro cal- 
loso-reflexo ; sordide jkwicanie, labro albo. 
The soiled Paetula. Shell oblong, thick, umbilicated, 
whorls five in number, convex, obliquely striated, 
very finely spirally impressly lineated towards the 
1850.
