This descrii)tion from a small specimen from Kawatana. 

 Coasts of fJapan. A large shark, generally connnon. Specmiens 

 ;vere seen at Hakodate, Tokyo, Wakanoura, Kawatana, and Nagasaki. 

 -Vhead in Yahiro's collection is from a specimen r^Jo feet long, and said 

 po have weighed iJ,0()O pounds. It presents the following characters: 

 I Snout rather short, acute, bluntish at tip; nostrils midway between 

 ;ip of snout and mouth; the eye nuich nearer angle of mouth; width 

 ;)f mouth almost twice leng-th of snout; teeth not large, uppermost 

 j'aintly serrate, subtriangular, without distinct notch on lower margin, 

 lind lower teeth erect, ahnost entire, long, narrow. 

 , In young of 3 feet the snout is ol)tuse, and a little longer than 

 jiiouth is broad; eye about midway between angle of UKmth and snout; 

 beeth weakly serrate, small, u})pei- bi-oad, not notched, nearly erect, 

 iind lower narrow; second dorsal small, sniallcr than anal; pectoral to 

 |iear end of dorsal, long, nai'row; first dorsal not dusky; second dor- 

 sal, pectoral, and lower lobe of caudal tippcnl with black. 

 I This species has ))een identitied with ('(wrJiiirias (/ang<4ictis^ Car- 

 bhar/as nieJ<()U)pt( rux^ and C<ircJi<()'l((>< hlith'rl, but it seems to be dis- 

 ':inct from all other East Indian and Polynesian s})ecies, and there 

 Jeems to be no evidence that any of these occui' in flai)an. ('archarlas 

 \nela7iopterus of Polynesia has the tin lo])es much blacker than in 

 \G. jaj>on!cHS. 



i One small specimen from Nagasaki difl'ers only in liax ing a slightly 

 I'nore pointed snout.
