Godwin-Austen has published a synoptical list of species of 

 this group, which I follow. He subsequently printed descrip- 

 tions of several additional species without indicating their rela- 

 tionships ; and here again I follow him. But few of the species 

 of Kaliella and Sitala are accessible to me ; judging from these, 

 and the figures of the others, I think too many species have been 

 made, the distinctive characters in some instances being very 

 tin elj- drawn. I add a few Chinese species. Dr. Kobelt supposes 

 that most of the forms of Conulus described from Japan also 

 belong to this group ; but I prefer to leave them in Conulus until 

 those who have better opportunities shall definitely ascertain 

 their position.
