since been associated by the writer with " Harriotta " vacifica : the 

 second, of great length, was found 1«» belong to ('. phantasma ; bul 

 the third egg-case remained unaccounted for. It showed clearly, 

 however, thai new species of Chimaera was to be looked for on the 

 Japanese coast : and it was further obvious that the species w;is 

 notably smaller than the com mn one. For the eersr-case (PI. I. Fis 

 'J) was distinctly smaller, its measurements being 22 by 2.7 cm., as 

 opposed to 27 by 3.5 cm. (C. phantasma). Thai the difference in 

 these egg-cases is nor one merely of size is ai once seen in the 

 smoother texture of the smaller egg-case, and. by the differenl model- 

 ling of the apex of the larger end. 



Accordingly I tried to colled the unknown species during my 

 stay in Misaki ; bul my efforts mel with no success, the fisher people 

 not appearing to know of a smaller species of " gin same," which 

 they probably confused with immature specimens of G. phantasma. 

 Just before the close of my stay, however, my search was rewarded : 

 among a number of small specimens of Chimaera broughl me was an 

 adult of a now species, which, as the possibility is not great of getting 

 a second small species of Chimaera in the same locality, readily 

 answered as the parent form ef the undetermined egg. 



The specimen proved to be an adult male (PI. I, Fig. 1) measur 

 ing <)<> cm. in length, smaller, therefore, than the full-grown male 

 of Chimaera phontasma by aboui 25 cm. Its color was dark sepia 

 below, blackish above, with here and there clouded lighter areas. A 

 conspicuous feature is the greater relative size and strength of the 

 dorsal spine: it projects beyond the tip of the succeeding fin rays, 

 and shows serration, not only on its lateral borders, but on its 

 anterior rim. The opisthure is of extraordinary length equalling : /:; 

 the length of the entire animal. In spite of this, the caudal fin itself 

 is oi relatively large size, as is also the continuous dorsal fin. The
