ened and reflexed, and of a polished pink carnelian appearance within ; 

 columellar margin triangularly dilated, overhanging the umbilicus. 



Diameter, greatest T10, least 0*83 ; height - 80 of an inch. 



Hab. Mount Dryander, Port Denison, Queensland. 



6". Helix o'connellensis, sp. nov. (Plate III. figs. 4, 4 a.) 



Shell with a wide, open, funnel-shaped umbilicus, semiglobose, 

 smooth, base flat and much excavated round the umbilicus, blackish 

 chestnut, rather solid; spire obtuse; whorls 6; suture margined 

 with a rather broad white line ; aperture oval, lilac within, darker at 

 the lip, which is expanded throughout ; margins approaching, 

 columellar margin broadly expanded and overhanging the funnel- 

 shaped umbilicus. 



Hab. The O'Connell River, Port Denison, Queensland. 



Diameter, greatest 1*15, least - 87 ; height - 85 of an inch. 



Closely allied to and resembling H. rainbirdi, Cox, in the exca- 

 vated base around the umbilicus ; but it is a smaller species, and 

 easily distinguished from H. rainbirdi by its white-margined suture. 



7. Helix whartoni, sp. nov. (Plate III. figs. 5, 5 a.) 



Shell deeply, openly umbilicated, depressedly globose, thin, finely 

 striated, profusely banded with yellow and light-chestnut bands vary- 

 ing in width and slightly undulating ; spire slightly raised ; whorls 

 6|, rather flat, last whorl descending in front ; aperture lunar-oval, 

 margins approaching, joined by a thin callus ; lip slightly thickened 

 and everted ; columellar margin triangularly dilated, half concealing 

 the umbilicus ; aperture pearly within. 



Diameter, greatest 1'53, least 1*15; height 1*10 of an inch. 



Hab. Port Denison, Queensland. 



This is a very constant species, and in great abundance, showing 

 but little variation. It is allied to H. appendiculata, Reeve, but is 

 a thinner and lighter shell and more depressed.
