really belong to it,*' as I had written, " It appears doubtful whether 

 typical Chaw pa has yet been recorded " from Australia. 



In this subgenus (Champa) Suter distinguishes five groups, and here 

 again he has utilized the protoconch features to a large extent, exactly 

 as I had done, though my work was quite independently performed. 

 Inasmuch as the coincidence is fairly exact, and I was working upon Aus- 

 tralian material, kindly loaned me by Mr. J. H. Ponsonby, whose collection 

 of these shells is very complete, and also extra-limital Pacific shells, while 

 Suter was criticizing Neozelanic shells, the groups may be considered quite 

 natural, and I here propose some of the generic names I had conferred in 

 my manuscript dealing with Australian shells. Many others will later be 

 proposed by other workers as well as myself. I introduce, — 



Egestula gen. nov. Type : Helix egesta Gray, 1850. 



Fectola gen. nov. 4 Type : H. infecta Reeve, 1852. 



Mocella gen. nov. Type : H. corniculum Reeve, 1852. 



Cavellia gen. nov. Type : H. biconcava Pfeiffer, 1853. 



The genus Ptychodon as hereafter admitted is polyphyletic, but none of 

 the species assigned to Thautnatodon by Suter agree at all with the type he 

 has named. 



My nomination of the genus Endodonta of Suter would then read, —
