colour. It is of a rich purple-brown, with, only a few irregular 

 streaks of creamy white, and a sub-basal yellowish band, which 

 appears quite white within the aperture. 



Family PUPIDiE. 

 Pupa pacifica, PfeiflFer. B.M. 



Bulimus pacificus, Pfr., Proc. Zool. Soc. 1846, p. 31; id. Mon. 

 Hcl. ii. p. 309 ; Kiister Conch. Cab. pi. xix. fig. 26-28 ; Smith, Zool. 

 Erebus, Moll. p. 3, pi. iv. fig. 6; Cox, op. cit. p. 68, pi. xiii. fig. 3. 

 Hab. — Hardy Island, N. Queensland (Pfr.), Mabuiag, Torres Straits 

 (Haddon) ; Pigeon Island, near Wallaby Island, Houtmans Abrolhos, 

 W. Australia (Smith) ; Roebuck Bay, Baudin and Cassini Islands, 

 N.W. Australia (Walker) ; Brisbane, and other localities in. Queens- 

 land (Cox). 



All the specimens from Cassini Island are sinistral ; otherwise they 

 resemble the normal form. Jickeli considers this species synonymous 

 with the North American P. fallax of Say. It seems to me, however, 

 sufficiently distinct. It is less elongate, more pyramidal, the 

 peristome is differently reflexed, and there is a distinct parietal 

 tubercle close to the insertion of the outer lip. 



Pupa lepidula, Adams and Angas. 



Cox, op. cit. p. 69 (unfigured). 

 Sah. — Shark's Bay, W. Australia. 



Pupa contraria, n.sp. B.M. 



Testa sinistrorsa, rimata, fusco-cornea, oblique tenuissime striata ; 

 anfractus 5^ convexi, sutura profunda sejuncti, ultimus penultimo vix 

 latior, antice asccndens ; spira elongata, convexa, pyramidalis, ad 

 apicem subglobosa ; apertura longit. totius fr adajquans ; peristoma 

 album, expansum, marginibus callo tenui, prope insertionem labri 

 tuberculoso, junctis. Longit. 4*5, diam. 2 mm. Apertura 1"5 mm. 

 longa. Hah. — East Wallaby Island, Houtmans Abrolhos (Walker). 



This species may possibly prove to be the sinistral form of 

 P. adelaidce, Ad. and Angas, which is only known to me by the 

 description. 



Pupa Lincolnensis, Cox. B.M. 



Cox, op. cit. p. 80, pi. xiv. fig. 16. 



Hah. — Port Lincoln, South Australia (Cox) ; Pigeon Island, near 

 Wallaby Island (Dr. Richardson, in British Museum), and East 

 Wallaby Island, Houtmans Abrolhos (Walker). 



This species is described as having only a single tooth or tubercle 

 in the aperture. The specimens collected by Dr. Richardson and 

 Mr. Walker have a second basal tubercle as indicated in Cox's figure, 

 and a third far within upon the cohimella. It is possible that in 

 the examples examined by Dr. Cox the denticles were only feebly 

 developed, or they may oven have been overlooked, being rather 

 indistinct.
