13. Leucogobio jordani Ishikawa. 



Local name : Yanagi moroko. 

 One typical specimen, 7.3 cm. long' measured to caudal base. 

 Obtained at Tokiwa, Dec. 1906. 



One other specimen, 9.3 cm. long measured to caudal base was 

 obtained at Iba in May 1907. 



The specimen bears the local name " Ilonmoroko." It closely 

 agrees with Leucogobio jordani, described and figured by Dr. Ishikawa, 

 but differs from this in the origin of dorsal being slightly nearer to 

 the origin of rudimentary caudal rays than to the tip of snout, 

 and in the same being farther from the base of middle caudal rays 

 than from the tip of snout. Nevertheless, I consider the specimen to 

 be not sufficiently differentiated to base a distinct species upon it ; 

 so that I have referred it to Leucogobio jordani Ishikawa. 



14. Leucogobio mayedae Jortlan & Snyder. 



Local name: Dcnie moroko; Yanagi moroko; Moroko.
