number of scales and the depth of the body. In addition he asserts: 

 "If we regard the specimens from near Peking as a distinct species we 

 shall be obliged to regard many varieties of the same species found in 

 other parts of China and in Japan also as distinct species, which is 

 inadmissible in consequence of the known variability of anguilli- 

 caudatus." 



It is certain that there is no specific difference between Chinese and 

 Japanese M. anguillicaudatus ; however, it is also true that in China and 

 Formosa there exists a large-scaled species of Misgurfius (Basilewsky's 

 Cohitis decemcirrosus or Giinther's Misgurnus mizolepis) which is 

 distinctly separate from common M. angiiillicaudaUis. According 

 to Berg's statement all the specimens of Misgurnus which were 

 examined by him belonged to M. anguillicaudatus, not M. decemcir- 

 rosus, differing in having more than 145 scales in the lateral series. 

 Not only is the large-scaled Misgurnus decemcirrosus not a nominal 

 species, but it is proved that it is distributed in Northern and Southern 

 China as well as in Formosa, distinctly differing from the common 

 loach, Misgurnus anguillicatidatus. Therefore Berg's opinion with 

 reference to M. decemcirrosus is incorrect.
