This appears to be the most widely distributed species in 
the family. It has been described under three different names 
from three of the lakes of Yunnan, from Erh-hai, from Hai-si in 
the same district and from Kun-yang-hai near Yunnan-fu. I 
have nothing to add to what was said by Dr. Baini Peashad 
and a self in 1919. 
om Jullienia it differs in the structure of the animal and 
the patible as well as of the shell. 
Family MELANIIDAE (Tiaridae). 
This family, as I have already pointed out, is poorly re- 
presented in the fauna of Yunnan and the only specimen in the 
Saperias s collection is a distorted shell of Melanoides from 
Bhamo in Burma. The three species recorded from the Pr 
ince all seem to belong to the genus Semisulcospira ey oe 
but | have not seen Heude’s Melania aristarchorum.2 1 hav 
however, examined shells of M. dulcis and M. lauta Fulton § 
from Kun- yang-hai, both of which certainly belong to the 
genus. The operculum of the former is somewhat peculiar ; it is 
80 broadly ovate as to be almost subcircular, but the structure 
is that characteristic of Semisulcospira and Melanoides resem- 
bling that of S. libertina (Gould), the type-species of Semisu 
cospira, much more closely than it does that of M. Subrculiles 
(Miiller), the type- species of the other genus. 
Family VIVIPARIDAE. 
Genus Vivipara (aucl.). 
The majority of the Chinese species of Vivipara belong to 
& peculiar group which we may call Viviparae rapes ares. e 
shell is elongate and more or less conical, rimate and somewhat 
flattened at the base, acuminate, usually rather thick. Solid, 
smooth or almost smooth spiral ridges are frequently present 
upon it and at least traces of them can always be distingnished. 
The colour is olivaceous, often with black vertical streaks ; dark 
Spiral bands are absent. The radula and operculum agree with 
those of /. vivipara and Mr. Srinivasa Rao, who has dissected 
several Chinese forms, finds no constant anatomical ari 
ape! except that the number of advanced embryos in the uterus 
mall.
