Margarya
''Margarya'' is a genus of large operculate freshwater snails, aquatic gastropod mollusks in the family Viviparidae.Bouchet, P. (2014). Margarya G. Nevill, 1877. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=758767 on 2014-12-10 Taxonomy The genus ''Margarya'' was described by Nevill (1877) based on shells of the type species collected by A.R. Margary from Lake Erhai, the type locality of ''Margarya melanioides''. Based on shell and radular morphology, Tchang & Tsi (1949) revised this genus for the first time and recognized seven distinct species. He created two subgenera of ''Margarya'' , viz ''Tchangmargarya'' and ''Mabillemargarya''. The first molecular phylogeny showed that the genus ''Margarya'' is polyphyletic and divided into three distinct clades. Combining study of comparative morphology and molecular phylogeny, Zhang ''et al''. revised the systematics of ''Margarya'' and recognized eight genuine extant sp ...

Erhai Lake
Erhai or Er Lake (), is an alpine fault lake in Yunnan province, China. Erhai was also known as Yeyuze () or Kunming Lake () in ancient times. Etymology The character "æ´±" (er) does not have the same meaning as ear (耳). During the Han to Tang dynasty, there was an ancient ethnic named ''Kunming Yi'' or Kunming Barbarian () lived in the neighbouring region of Erhai lake. Therefore, the lake was also called "Kunming Lake". The ''Kunming Yi'' has another name ''Kun-mi'' (). In the following time, Chinese literature recorded the name "昆弥" as "昆å¼" (Kun-mi) that "å¼" is a rebus of "å¼¥". And the name of the lake was also be changed to the character "渳" (mi) which has a water-meaning radical () attached to it. Fang Guoyu believe the name "æ´±" (er) was simplified from "渳", after that the name "Erhai" continues to this day. According to Bai scholar's research, the "Yeyu" in the Chinese name "Yeyuze" (''ze'' ³½means lake) is evolved from Bai language which means "lower wa ...
