( '. monstrosa, a détermination which has since been generally followed 

 by both European and Japanese authors. Recently, however, Jordan 

 and Snyder, studying the matter with greater care, have concluded 

 that the Japanese species is distinct, and have given it the name o 

 C. phantasma, describing it in the Proceedings of the United States 

 National Museum for 11)00, Vol. XXIU, pp. 338-339. 



The latter authors distinguish it as follows : — C. phantasma 



•• ditfers from ('. monstrosa having much longer pectoral fins and 



larger eyes." " Pectoral fin pointed ; l 2 / 3 as long as the dorsal spine ; 

 when depressed its tip reaches middle of ventral." " Second dorsal 

 fin a little higher than diameter of pupil ; the posterior edge round- 

 ed ; separated from caudal by a deep notch. Anal fin low, pointed 

 posteriorly ; separated from anal by a dee]) notch below the end 

 of the dorsal. The lower caudal membrane extends posteriorly much 

 fart lier than the upper." 



Further than in the above notices the Chimaeras of Japan have 

 received little attention.* And 1 was therefore led to collect notes 

 upon them during my stay at the Misaki zoological station, where 

 the conditions were naturally favorable for my work, and where the 

 Imperial University granted me the most generous privileges. To 

 the University, and to the director of the station, Professor Mitsukuri, 

 I. am, accordingly, under dee]) obligation. I wish, also, in this con- 

 nection, to express my sincere thanks to Prof. S. Watase, of the 

 Imperial University of Tokyo, for his kindness in editing the present 

 paper and in correcting the proof. 



The present notes refer to the characters of C. phantasma, and 

 include a description of a neVv species — G. mitsukurii, together with 

 reference to the i 1 ^ cases of both forms.

 clearly distinct from Japanese forms. (Mem. Australian Mus. IV, pi. I, p. is. pi. v l |
