Art. XXVI. — A New Variety of Volute from Western 

 Australia. 



By AGNES F. KENYON. 

 [Read 12th December, 1912]. 



Voluta nivosa, var. coxi. 



Shell, dull red colour. This dullness may be owing to being 

 a dead specimen ; ovately oblong, spire short, lower whorls noduled, 

 upper whorls slanting from apex and noduled. These are almost 

 obscure when touching body whorl at an angle. Columella four 

 plaited, snowflake marking large on body whorl, and in most 

 respects resembling original description of V . nivosa. The differ- 

 ences consist in the largeness of the size, difference of colour, and 

 the tuberculation of the whorls, also colouring of interior, which 

 is lemon colour merging into orange. 



Greatest length. 5 inches. Greatest breadth, 2 inches. 

 Greatest circumference, 6^ inches. 

 Locality. — Garden Island, W.A. 



There are now several varieties of V . nivosa, but in colouration 

 and form the most remarkable of these varieties is the recently de- 

 scribed var. irviniana of E. A. Smith, owing to its coronal spikes, 

 whereas V . coxi, although of the same ruddy hue, has reverted to 

 the original shape of V . nivosa as described by Lamarck, but is of 

 iiiucli larger size. 



The specimen now described is from the collection of Mrs. J. F. 

 Irvine, Evandale, Tasmania, and is named as a tribute to the late 

 Dr. J. C. Cox, of Sydney, whose lamented death is a great loss to 

 the scientific world.
