ON THE SPECIES OF WHITE CHIMERA FROM JAPAN. 



By David Starr Jordan and John Otterbetn Snyder, 



Of the Leland Stanford Junior University. 



In a review of the Elasmobrancliiate fishes of Japan l\v Messrs. 

 Jordan and Fowler in these Proceedings," the specimens of white 

 Chhnwra!^ or Ginzame collected by Jordan and Snyder in Japan are 

 all referred to Clihacera phantaKina. A reexamination of the same 

 material shows that two species are included bj^ Jordan and Fowler 

 under this head. One of these is the original Chrnupra i>hantas)ii(i of 

 Jordan and Sn3'der'' from the market of Tok3'o. The other is the 

 Chimmra phantasma of Jordan and Fowler,'* from a specimen from 

 Saga mi Bay. 



The latter is a new species, and Dr. Bashford Dean tells us that 

 he has proposed for it, in a paper still unpublished, the name of 

 Chitiuera mitsulcKrll. This name we accept in place of one devised 

 by ourselves. The two smaller specimens mentioned b^- Jordan and 

 Fowler'' are the 3^oung of ChinicBra phantasma. All the specimens 

 of both species now extant came from Sagami Bay, off Misaki. 



The s}'nonymy and distinctive characters of the two species are 

 given below. The accompanying figures are b^^ Mr. AV. S. Atkinson, 

 that of Chiramra pKantafuna being from the original tvpe, No. 49398, 

 U.S.N.M.
