Sab. Arnheim's Land, N. Australia. 



Like the majority of the figures in Sowerby's monograph of 

 this genus, that of the present species is altogether ditferent from 

 nature. 



The type is of a pale olivaceous horn-colour, and not the vivid 

 red represented in the work referred to. The form, too, is incor- 

 rectly drawn ; for in neither of the two specimens in the Museum 

 are the sides of the last whorl flattened as there delineated. 



99. Phtsa (Gltptophtsa) alici^, Seeve. 



Physa alicijE, Peeve, Proc. Zool. Soc. 1862, p. 106, woodcut; Sowerby, 

 Con. Icon. fig. 6 b. 



Sab. Murray and Gawler rivers, South Australia ; Eiver Onka- 

 paringa, at Noarlunga {Molineux). 



The description of this species by Sowerby is incorrect with 

 regard to colour; and the locality "India" is also wrong. The 

 shell is whitish, clotiied with a pale dirty straw-coloured epidermis. 

 The Museum possesses two s])ecimens of an interesting variety 

 presented by Mr. Gerard Krefft ; they differ from the normal 

 form of the species in having the spiral ridges both fewer and less 

 elevated.
