ON A COLLECTION OF FISHES MADE BY MR. ALAN 

 OWSTON IN THE DEEP WATERS OF JAPAN 



By DAVID STARR JORDAN and JOHN OTTERBEIN SNYDER 



The writers have recently received from Mr. Alan Owston, of 

 Yokohama, well known as a shipmaster and as a collector in natural 

 history, a very remarkable series of fishes obtained on long lines in 

 the depths of Sagami bay and Siiruga bay, Japan. The present 

 paper contains notes on these species, together with field notes of 

 Mr. Owston. The specimen of Mitsukurina otvstoni and some of 

 the others have been sent to the United States National Museum. 

 The rest are in the collection of Leland Stanford Junior University.
