Bulimus Carteriensis, Pfeiffer. 
Ilab. Port Carteret, New Ireland, Pacific Ocean ; Quoy. 
Allied to P. liyalina, but of a more compressed oblong 
form and of a substance rather more opake. 
Species 18. (Fig. a, b, Mus. Cuming.) 
Partula auricula. Part, testa oblongo-conica, solidius- 
cula, basin versus oblique produetd, subumbilicaid, an- 
fraclibus planiconvexis, Icevibus, ultimo basi obsolete 
carinato, aperturd subquadrato-ovali, laminis duabus 
prominentibus erectis intrantibus munita ; alba, nunc 
luteo, nunc rtfo-fusco cingulatd. 
The ear Partula. Shell oblong-conical, rather solid, 
obliquely produced towards the base, slightly umbi- 
licated, whorls flatly convex, smooth, last whorl ob- 
soletely keeled, aperture somewhat squarely ovate, 
with two prominent erect lamime entering into it ;

The chief peculiarity of this little species consists in 
the presence of two sharp erect lamina;, which enter the 
aperture, one on the columella, and another on the body- 
whorl, which is not a modification of the callosity often 
present in that part of the shell. 
Species 19. (Mus. Cuming.) 
Partula gonocheila. Part, tesla subabbreviato-ovatd, 
ventricosd, compresse umbilicata, anfraetibus rotundatis, 
oblique irregulariter strialis, lineis impressis spiralibus 
minute sculptis, aperturd ovatd, columelld labroque 
tail planirefexis, labro superne leviter contracto ; semi- 
pellucido-fulvd, epidermide tenumimd, interdum bifas- 
ciaid, induta. 
The angle-lipped Partula. Shell somewhat abbre- 
viately ovate, ventricose, compressly umbilicated, 
whorls rounded, obliquely irregularly striated, mi- 
nutely sculptured with spiral impressed lines, aper- 
ture ovate, lip and columella broadly flatly reflected, 
lip a little contracted at the upper part ; semitrans- 
parent fulvous, covered with a very slight epidermis, 
sometimes disposed in two bands. 
Pfeiffer, MS. (Mus. Cuming). 
Hab. Navigators’ Islands, Pacific Ocean. 
A somewhat globose semitransparent shell, with an 
extremely delicate epidermis, which is partly bi-mem- 
branous and hydrophanous in bands. 
Species 20. (Mus. Cuming.) 
Partula compressa. Part, testd acuminato-oblonga, 
crassiuscula, basin versus oblique produetd, subampliter 
compresse umbilicata, anfraetibus convexis, oblique stria- 
tis, vix spiraliter lineatis, anfraclu ultimo basi rotun- 
dato-angulato, aperturd oblonga, labro declivi-reflexo, 
superne leviter contracto; intense custaned, labro el 
apertures fauce livido-purpureis. 
The compressed Partula. Shell acuminately oblong, 
rather thick, obliquely produced towards the base, 
rather largely compressly umbilicated, whorls convex, 
obliquely striated, very slightly spirally lineated, last 
whorl rotundately angled at the base, aperture ob- 
long, lip reflected in a slanting direction, a little 
contracted at the upper part ; dark chestnut-brown,
