COLLIER: GENERA AND SECTIONS OF THE PUPININ^E. Ill 



The following is the arrangement of Fischer as to the genera and 

 section of the Pupininte, 



Sub-Family PUPININ^. 



Genus Pupina Vignard, 1829. 



Shell pupiform, or shaped like a Pupa, shining, glossy, sometimes 



transparent, epidermis in some species resembling a thin coat of 



varnish, peristome strong or reflected, mouth round, operculum 



circular, thin, membranous, underside flat, with a central nucleus. 



Distribution : Indo-China, Japan, Malaysia, and Australia. 



Section Pupina sensu stricto {Eupupina L. Pfeiffer, 1876). 

 The edge of the columella with a transverse slit or channel to the 

 middle, and a second channel near the insertion of the parietal whorl. 



Type P. keraudreni Vignard. 



This is by far the most numerous section, as according to Paetel out 

 of sixty-four species that he mentions, although many more species 

 have been discovered since his work was published, more than 

 one-half belong to this section. There is, as you will see, a very con- 

 siderable difference in the depth and width of these channels or 

 notches. Some of them, as P. bidentata of C. E. Beddome from 

 Queensland, and P. pulcheila of MUdff. from China, have deep and 

 long slits or channels, with strong ribs or thickenings on each side, 

 whilst others like P. keraudreni Vignard, from the Caroline Islands, 

 have only very small and slight channels or openings. 

 Section Registoma Van Hasselt, 1823 (=Moulinsia Grataloup, 1841). 



The edge of the columella channelled to the middle. The edge of 

 the parietal wall plain. 



Type R. grande Gray. 



Very different from the section Pupina in having only one channel 

 and that at the base of the mouth. 



Section Bellardiella T. Canefri, 1883. 



Type B. martensiana T. Canefri, from New Guinea. Basal 

 channel open at the back behind the peristome. 

 Section Hargravesia H. Adams, 1870 {=Hyalopsis Pease, 1872). 



Only one channel at the upper part of the opening. 



Type H. polita H. Adams, from the Solomon Islands. 



Easily distinguished from Registoina as the channel is at the upper 

 part instead of the lower. 



Section Callia Gray, 1840. 

 Without any channel. 



Type C. lubrica Sow., from the Philippine Islands, 

 These four are the sections of what Fischer considers as true 

 PuphicB.
