GENUS AND TEN NEW SPECIES OF JAPANESE FISHES. 3 



caudal, where it runs nearer lower outline than the upper ; ex- 

 tending to tip of tail. 



Colour in formalin dark gray, paler beneath ; ever}^ fin with 

 blackish anterior and whitish posterior edge ; interior of mouth 

 as well as edge of gill-openings and of nasal valves blackish. 



The species is distinguished from all others of the genus by 

 having longer snout, equal dorsals, and much larger anal. 



The species is not rare in the neighbourhood of Misaki, 

 Province Sagami. The type, a young male, was captured by 

 Mr. AoKi in April 1909 ; it is registered in the University col- 

 lection under No. 2153. A second larger skin is also preserved 

 in the collection ; it is altogether similar in configuration to the 

 type.
