justifiable by any rule of zoology, but one in which he is followed 

 by Tryon. On turning to p. 17 of Tryon's Manual, 2nd Series, 

 Vol. iii., the negligence with which this group is treated is at once 

 apparent ; Charopa and Pitys, though, as Pease remarks, doubt- 

 fully distinct, are sundered into different families ; the type 

 of Endodonta is misquoted as huahinensis ; Pitys is wrongly 

 fathered upon the brothers Adams and misdated 1855, 

 while no intimation is given of the preoccupation of Libera, 

 pointed out in Zoological Record, 1881, Index, p. 8. So many 

 errors upon a single page sufficiently destroy our confidence in 

 the treatment of the group by this monographer. 



To summarise : I would consider that "Pattda" has no existence 

 in the Pacific ; that the southern species usually referred to that 

 genus are not even of the Helicidoi family ; that these species 

 can most conveniently be referred to one or other of the genera 

 enumerated above, which genera may be grouped under the sub- 

 family Charopidce, a division of the family ZonitidcB. 



None of the recorded descriptions fulfilling the exacting require- 

 ments of modern malacology, I propose in this and subsequent 

 communications to refigure and redescribe all the Australian 

 Charopidte of which I can obtain authentic specimens. Having 

 .studied the material accessible to me, I shall then consider the 

 value of the proposed generic divisions ; provisionally, all will be 

 quoted as " Charojja." 



The following descriptions and accompanying figures are based 

 upon the author's types, most kindly placed at my disposal for 

 that purpose by my friend Lieut. C. E. Beddome, R.N., of Hobart, 

 Tasmania.
