PEESHWATEE SHELLS OF AUSTEALIA. 277 



48. Phtsa not^-hollandije, Blainville. (Plate Y. figs. 19- 

 20.) 



Physa novae-hoUandise, Bl. Man. de Malacol. 1825, p. 450, pi. xxxvii. 

 figs. 3-3a. 



Sal. New Holland. 



Blainville's figures, now reproduced, wbicli are evidently very 

 inaccurately drawn, represent a shell of unusually large size, with. 

 a much prolonged columella and aperture. A specimen in the 

 Museum collection, which approaches the figure considerably 

 in form, is a variety of P. protetts, Sowerby (Con. Icon. fig. 43 a). 

 However, the mouth is more oblique and not so prolonged in- 

 feriorly, and the apex of the spire is more acute. Another species 

 which bears a closer resemblance to Blainville's figure is the 

 Aplexa aurantia of Carpenter ; but this is an inhabitant of Cali- 

 fornia, and consequently, if the locality given by Blainville be 

 correct, it is very remarkable that Australia and North America 

 should possess species so very similar. 



49. Phtsa Lessoni. (Plate V. figs. 21-22, after Lesson.) 

 Physa novfe hoUandise, Lesson, Voy. Coquille, vol. ii. p. 332, pi. xvi. 



figs. 5-5"; Xilster, Con.-Cab. p. 18, pi. ii. figs. 20-22. 



Sab. Macquarie River. 



The name employed by Lesson having already been assigned to 

 a species by Blainville, I here substitute that of Lessonii. I have 

 not been able satisfactorily to identify any specimens in the 

 Museum with this species; but certain forms of P. proteus 

 approach it rather closely. 



50. Phtsa georgiaka, Quoy Sf Gnimard. (Plate V. figs. 23-24.) 

 Physa georgiana, Quoy 8f Gaimard, Voy. de V Astrolabe, vol. ii. p. 207, 



pi. Iviii. figs. 23-24; Kiister, Con.-Cab. p. 25, pi. iv. figs. 13-14. 

 Sah. " Le port du Eoi-Georges, a la JSTouvelle-HoUande." 

 The figures here given are copied from the ' Astrolabe.' 



51. Phtsa G-eati. (Plate V. fig. 25.) 



Physa novaj-hoUandiaj, Gray, Griffith's ed. Cuvier's Animal Kingdom, 

 pi. xxvii. fig. 4 ; Sowerby, Con. Icon. fig. 10. 



Sal. New Holland. 



In this instance Sowerby figures Grray's JP.novce-'hollandicB, and 

 gives the reference to that described by Blainville under the same 

 name. The species may eventually prove a variety of the variable 

 P. gihlosa.
