 Bulimus Carteriensis, Pfeiffer. 



Hab. Port Cai-teret, New Ireland, Pacific Ocean ; Quoy. 



Allied to P. hyalina, but of a more compressed oblong 

 form and of a substance rather more opake. 



Species 18. (Fig. a, 4, Mus. Cuming.) 



Partula auricula. Part, testa obloiiffo-conicd, solidius- 

 culd, basin versus oblique productd, subumbilicatd, an- 

 fractibus planiconvexii, lavibus, ultimo basi obsolete 

 carinato, aperturd subquadrato-ovali, laminis duabus 

 promiiientibus erectis iiitranlibus muuifd ; albd, nunc 

 luteo, mine rufo-fusco civgulatd. 



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 lamina? entering into it ; 

 white, encii-cled sometimes with yellow, sometimes

Auricula sinistrorsa, Chamisso. 

 Bulimus armatus, Mighels. 



Hab. Sandwich Islands. 



The chief peculiarity of this httle species consists in 



the presence of two sharp erect laminae, 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, testa subabbreviuto-omtd, 

 ventricosd, compresse umbilicatd, anfractibus rotundatis, 

 oblique irregulariter striatis, lineis inipressis spiralibus 

 minute sculptis, aperturd ovatd, columella labroque 

 late planireflexh, labro superne leviter contracio ; semi- 

 pellucido-fulvd, epidermide tenuissimd, interdum hifas- 

 ciatd, indutd. 



The angle-lipped Partula. Shell somewhat abbre- 

 viately ovate, ventricose, compressly umbilicated, 

 whorls rounded, obliquely in-egularly striated, mi- 

 nutely sculptured with spii-al 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-meni- 



branous and hydrophanous in bands.

Partula compressa. Part, testd acuminato-oblonyd, 

 crassiusculd, basin versus oblique productd, subampUler 

 compresse umbilicatd, anfractibus convexis, oblique stria- 

 tis, vix spiraliter lineatis, anfractu ultimo basi rotuu- 

 dato-angulato, aperturd oblongd, labro declivi-refie.co, 

 superne leviter contracio; intense castaned, labro et 

 aperturce fauce livido-purpureis. 



The compressed Partula. Shell aeuminately obloug, 

 rather thick, obliquely produced towards the base, 

 rather largely compressly umbilicated, whorls convex, 

 obliquely striated, very slightly spii-aUy lineated, last 

 whorl rotundately angled at the base, aperture ob-
