XVII.' — The Origin of the Manchurian Fishes. 



The fishes of Manchuria are of great interest and re- 

 present the group most investigated of all the animals. 

 Thanks to the works of Dybovskii, Hertzenstein, ProfL Berg, 

 Soldatow, and Schmidt here in the Amur basin are known 90 

 different forms. This quantity is very large and surpasses 

 in its diversity the fish fauna of any other river in Asia. 

 For the fishes of the Amur river and Manchuria Prof. L. C. 

 Berg arranges a particular Manchurian ichthyological district 

 and relegates to it all the basin of the Amur river, Suifun and 

 Tumen-ula draining into the Japanese sea. This district is 

 remarkable for the mixture of the northern and southern 

 forms. Here, similar to the species coming from the basins 

 of Siberian rivers, flowing into the frozen ocean, are found 

 southern fishes, as Ophiocephalus (see fig. 1), Hypoph- 

 thalmichthys, Elopichthys, etc. Besides that to this district 

 are peculiar some endemic genus and species as, Pseudaspius 

 leptocephalus ; Mesocottus heity (see fig. 2), — one form of 

 bullock not commonly exceeding 20 cm. in length, with gray 

 coloured sides and back which is covered with small thickly- 

 laid prickles. The head is very wide and flattened, the 

 pectoral fin is fully developed; dahurian hausen (Husa 

 dahurica) — a fish growing to an enormous length, weighing 

 about 280 pounds; the amurian sturgeon; Leptobotia mans- 

 churica discovered by ProfL Berg — a fish with one dorsal fin 

 with a stretched and pointed snout. Its mouth is surrounded 

 with, fleshy lips and moustaches. It strikes ones eyes by the
