Obs. — On this species Professor Tate remarks that in size and 

 general appearance it is similar to L. subquadrata, T. Woods, 

 but its suture is not so excavated, the aperture not so explanu- 

 lately thickened, and its columella-margin is detached from the 

 umbilical rim. He further makes out a closer affinity for this 

 species with L. clathrata, Reeve, based upon actual comparison 

 with examples of the latter species. 



Family Cvclostre>]atidae. 

 Note.— In his recent revision of the Australian Cyclostre- 

 matidae and Liotiidae, Professor Tate remarks that the limits of 

 the genera Cyclostrema and Liotia are not so exact as to permit 

 in all cases of a safe reference to one -ar the other. The same 

 authority states that " the conchological characters largely relied 

 on for Cyclostrema are a thin vitreous test, entire, simple non- 

 varicosed aperture, and a multi-spiral operculum. For Liotia, a 

 stout perlaceous test, last whorl descending at the front, aperture 

 variced and entire, operculum spiral and covered with calcareous 

 granules." Hence we have Liotia angasi, Crosse, Liotia lodderae, 

 Petterd, and Liotia minima, T. Woods, referred to the above 

 family Cyclostrematidae, the first being referred to under the 

 generic ti'ole of Pseudoliotia, and the second and third under the 

 generic name of Lodderia.
