2 ART. 11. — S. TANAKA. 



Last winter, from the last part of January to the middle of 

 February, there were brought into Mr. Owston's office in Yoko- 

 hama twenty-three specimens of Chimœra, all taken in the Sagami 

 Sea, off the village of Inatori, Idzu. He generously turned them 

 over to me for examination. There also came about the same 

 time to the Zoological Institute of the Science College two speci- 

 mens from the Tokyo market, said to have come from the same 

 locality off Idzu. A careful examination of all these specimens 

 has convinced me that they do not belong to any of the hitherto 

 known eight species and that they must be referred to two new 

 species, for which the specific names jordani and owstoni are 

 proposed. 



It is necessary for me to add here that I am under very 

 deep obligations to Prof. Dr. Mitsukuei for superintending my 

 study and for his careful corrections of the manuscripts in the 

 preparation of this article. I wish also to thank Mr. Owston 

 for his generosity in placing his specimens at my disposal for 

 examination. 



CHIMiERA JORDANI n. sp. PL I., fig. 1. 



The points of the species which strike us at a glance are 

 (1) that the lateral canal of the sensory canal system runs straight 

 on the side of the body almost without any sinuation, (2) that a 

 deep notch lies between the anal fin and the lower lobe of the 

 caudal, and (3) that the head and body are of a uniformly 

 brown color. 



The following is a detailed description of the species. 



Head measured from tip of snout to first gill-opening con- 

 tained 4f times, and greatest height of body in front of the posterior
