A PRELIMINARY NOTE ON THE FISHES OF LAKE BIWA. 129 



11. Achilognathus sp. (?) 



Jap. name : Zako. Loc. Otsu. 



12. Leuciscus hakoneiisis, Gthr. 

 Jap. name : Ugui. Loc. Otsu. 



Giinther gives the name of the Lalie as Hakou and the specific 

 name of the fish as Jiakueiisis (Challenger Eeport), but the lake is 

 called Lake Hakone and the specific name should be halwnensis or 

 hahoneensis. 



13. Cyprinus carpio, L. 



Jap. name : Koi. Loc. Otsu. 



14. Carassius auratus, L. 



Jap. name : Funa. Loc. Otsu, Matsubara. 



Three distinct varieties of this fish are found in the lake, known 

 by the names of Mabuna, Hiwara and Ganzo. 



15. Genus (?) sp. (?). 



Jap. name: Wadaka. Loc. Otsu, Hikone, Nagahama. 



16. Misgurnus anguillicaudatus, Gthr. 

 Jap. name : Dojo. Loc. Matsubara. 



17. Cobitis Asenia, Gthr. 



Jap. name : Shimadojo. Loc. Otsu, Matsubara. 



The bifid suborbital spine is situated somewhat in advance of the 

 eye, making it thus nearer to the Genus Acanthopsis than to Cobitis. 



18. Plecoglossus altivelis, Schleg. (?) 



Jap. name : Koai. Loc. Matsubara, Maebara. 



This fish appears to be identical with P. altivelis, but it does not 

 seem to attain the size of the latter, the individuals with ripe eggs 

 remaining only in the length of seventy or eighty millimeters.
