Pupa Wallabyensis, n.sp. B.M. 



Testa dextrorsa, cylindracea, pellucida, alba, anguste rimata; 

 anfractas 5 perconvexi, sutiira profunda sejuncti, peroblique striati, 

 ultimus antice ascendens ; spii-a cylindracea, ad apicem obtusa ; 

 apertura minima, ringens, longit. totius ^ sequans, denticulis septem 

 inoequalibus (tribus parietalibus minimis, mediano maximo, uno 

 columellari magno, lamelliforme, tribus palatalibus magnis lamelli- 

 formibus) instructa ; peristoma leviter expansum, marginibus conni- 

 ventibus, callo tenui junctis. Long. 2*5, diam. 1 mm. Hab. — East 

 "Wallaby Island, Houtmans Abrolhos (Walker). 



The teeth of this species are very characteristic, and block up the 

 aperture to a considerable extent. The three parietal are much 

 smaller than the rest, and situated close together, the central one 

 being the largest. That on the columella is large, lamelliform, and 

 prominent. The central palatal tooth is narrow, long, and extends 

 inwards ; those on each side of it are shorter, but a trifle more 

 prominent perhaps. 



P. Macdo7inelli, Brazier, from Fitzroy Island, N.E. Australia, 

 is a little shorter than this species and has more feeble armature 

 in the aperture. 



Pupa Mooeeana, n.sp. PI. VII. Fig. 25. B.M. 



Testa brevis, cylindracea, rimata, fusco-cornea ; anfractus 5 per- 

 convexi, lente crescentes, oblique tenuiter striati, sutura profunda 

 sejimcti ; spira cyliudrica, ad apicem obtusa ; apertura rotundata, 

 dentibus quinque insequalibus (duobus palatalibus, uno columellari, 

 duobus parietalibus") munita, longit. totius i sequans ; peristoma 

 leviter expansum et reflexum, marginibus conniventibus. Longit. 2, 

 diam. 1 mm. Hab. — Roebuck Bay, W. Australia. 



The largest tooth is that situated on the whorl midway between tlie 

 ends of the peristome. It juts out into the aperture and points 

 between the two palatal denticles, which are about the same size 

 as that on the columella. The fifth tubercle is at the insertion of the 

 labrum. Named in honour of Capt. W. U. Moore, R.N., in command 

 of the " Penguin."
