Vol. XXV, p. 328.) 



The common Ayu is very abundant in all the rivers of Korea, including the 

 Yalu. Our specimens are from Fusan, and unusually large. It has not been 

 hitherto definitely recorded from the continent of Asia, and the limits of its 

 range are not known. 



Family ARGENTINID^. 



33. Osmerus dentex Steindachner. 

 Chinnampo (No. 4225a-b).

LXXXVI, fig. 229.) 



Dr. Berg (Ichthyologia Amurensis, p. 58) places Salmo inghaghitsh of Wal- 

 baum (Artedi Piscium, p. 73) as a doubtful synonym of Osmerus dentex. As 

 the teeth are said to be very small ("dentes minimi") it is not likely that this 

 can be an Osmerus. It can only be Mesopus olidus, which according to Pallas 

 is called "Inniacha" in Kamchatka. In that case the latter species should 

 stand as Mesopus inghaghitsh.
