far as I am aware these are the only examples of the species extant. 

 A second species of " Harriotta " was next described in 1895 by Pro- 

 fessor Mitsukuri as Harriotta 'pacifica. 2) Of this species, specimens have 

 up to the present time been taken in the single region, that of Misaki, 

 near the mouth of the bay of Tokyo, a locality which has become clas- 

 sic as the habitat of such rare and interesting fishes as Chlamydosela- 

 chus and Mitsukurina. As far as I am aware, all specimens of this 

 Japanese species, save one, have been obtained in the fish market of 

 Tokyo. Altogether seven individuals appear to have been preserved : 

 three of these are now in the Imperial University of Tokyo, the fourth 

 in the Museum of Comparative Zoology, Harvard University, the fifth 

 in the Bohemian National Museum at Prague, the sixth in Columbia 

 University, New York, and a seventh is now in the hands of Mr. Alan 

 Owston, of Yokohama. The male specimen, which is apparently uni- 

 que, was taken by the well known collector of the Misaki zoological 

 station, Kuma Aoki. This is one of those in the Tokyo Museum 3)

 is preserved in the National Museum at Washington.

3) The record of the specimens in Tokyo has been kindly forwarded me by Professor Mi- 

 tsukuri. The first was obtained April 19, 1883, and was said to have been caught near Kuriha- 

 ma ; the second, the male, was taken on May 9, 1898, by Kuma Aoki, on mutsu line, at a depth 

 •of about 400 fathoms, off the entrance of the bay of Tokyo, on the fisherman's ranges " Sengen- 

 zuka gaké : Xago hitotsu :" the third, which was brought to the museum during Professor Mitsu- 

 knri"s absence, 1898-99, has no definite label. 



The present paper was prepared during my visit to Japan (1900-1901). Since then I have 

 received from my friend Mr. Garman an important note, extr. from the Proceedings of the New 

 England Zoological Club, Nov. 2d. 1901, Vol. II pp. 75-77, in which he regards the Japanese 

 " Harriotta " as representing a new genus Ehinochimaera. Mr. Garman had had the privilege of 

 comparing critically a type of Harriotta raleigkana with a specimen of the Japanese form, and 

 found marked differences in the character of the dental plates. I myself have since had the op- 

 portunity of examining in some detail the same type of H. raleiglCàna, generously loaned me by 

 the Smithsonian Institution, and' I am able to confirm Garman's observation. Adopting the 

 new generic name I have thought it best to allow the present paper to be published as it was 

 written. I have changed my MS. therefore to read: " Harriotta " ^in quotation marks), tor the 

 Japanese form.
