Among some snails (kindly sent to mc Ijy Mr. F. J. Thomas, to 

 whom ray thanks are due) from Beech Forest, Victoria, were some 

 specimens of Paryphanta compacta. Figures, and a description, of 

 the shell of this new species of Faryphanta have been given by Dr. 

 Cox and Mr. C. Hedley in their " Index to the Land Shells of Vic- 

 toria, "i but no account has hitherto been given of the animal itself. 



The specimens of /'. atramentaria, which were used in this work, 

 were collected by myself about three years ago, at Blacks' Spur,, 

 near Healesville, Victoria. I did not use the animals at the time,, 

 and had only this preserved material for working this species. 

 Several descriptions of the shell have been given, but so far as I 

 know, the anatomy has been scarcely touched. I have been unable 

 to see Shuttleworth's original description in Mittheil. Naturf. 

 Gesell., Bern, 1852. 



External Features and General Description. 

 F. compacta. 



Dr. Cox and Mr. Hedley describe the colour of the shell as 

 " brown, deepening on the last whorl to black, and on the second 

 whorl passing into straw yellow." The animal itself is dark grey,, 

 with a lighter grey round the mouth and the side of the foot, be- 

 coming almost white down the mid line of the sole of the foot. 



I took measurements of preserved specimens to compare with F, 

 atramentaria. An average specimen measured : — 



Shell, maj. diam. 20 mm., min. diani. 16 mm., height 15 mm.; 

 sole of foot 20 mm. long, 10 mm. broad ; height of part outside- 

 shell, 8 mm.
