254 ON SOMK LAND SHKLLS COLLECTED IN QUEENSLAND, 



Panda whitei, sp.nov. 

 (Plate iv., tigs.l, •_'. 3.4.) 



Shell small fur the genus, imperforate, thin, translucent, broadly 

 auriform, spire short. Colour : on a tawny olive ground are 

 spiral lines of chocolate, varying from five to eight, irregulaily 

 broken into dashes, between the lines are numerous chocolate 

 specks. The nuclear shell is set with minute grains in radial and 

 spiral lines, after a whorl and a half it terminates abruptly at a 

 furrow. The adult shell is only a whorl and an eighth, its 

 smoothness is scarcely broken by faint, radial growth-lines. 

 Aperture very oblique, oblong, its margins connected by a film of 

 callus. Behind this and running in a spiral along the columella 

 is a sharp-edged callus-ridge. A faint purple glaze extends uMr 

 the interioi-. Height, 23: diameter, 18 mm. 



Several living specimens, under damp logs in dense scrub on the 

 mountain side, near Finch Hatton Creek, a bi-ancli of the Pioneei- 

 River, Port Mackay( August, 1 908). 



Mr. Jackson prepared a drawing of the extenrled animal from 

 life, which is here reproduced (Plate iv., fig.4). He noted that 

 the animal bore a general resemblance to P. larreyi and F. 

 falconeri. Even when retracted, it is too large to be contained 

 in the shell. Median area of the tail deeply excavate; from a 

 tapering longitudinal furrow, grooves branching in pairs descend 

 to the margin. Sides of the foot spreading in a broad flange. 

 Except the dorsal furrow, which is smooth, the upper smface is 

 tuberculate, the tubercles on the neck being larger and more 

 elongate than those on the side. The upper surface of the animal 

 is mo.stly a dull brown, the tentacles ivddish, the dorsal furrow 

 black, the saddle on which the shell rests whitish. In front, a 

 broader medial and two nari-ower lateral black lines, the latter 

 running to the tentacles. 'J'he sole pale brown. 



The genus Panda is the most handsome, and from its relations 

 with the Madagascar Ildicophanta, one of the most interesting 

 groups, of the Australian fauna. Revising the genus some years 

 ago,* 1 reduced the species to three, P. falconeri Ciray, P. atomata
