bought in Japan). 



No detailed description of this si)ecies has 3 et been given. Mitsu- 

 kuri's paper reads as follows: 



The reader's attentio* is called to Plate XVI, giving the figures of individuals of 

 the Chima'roid group. The lower figure is copied, somewhat redncetl, from the 

 April iium]>er of the American Naturalist, and represents the new chima-roid Harrl- 

 utl<( r<ilei(/}i(i)i.a, which Messrs. Goode and Bean discovered among the collection made 

 by the Albatroni^. Its habitat is said to l)e the coasts of Virginia, Maryland, and 

 Delaware, 707-1080 fathoms. 



The upper figure represents a chimicroid which has been for some j'ears in the 

 possessit)!! of the Zoological Museum of the Science College in the Imperial Cniver- 

 sity of Tokyo. The specimen (male) was liought in the Tokyo market and is marked 

 as from Knrihama, province of Sagntiii. There can be no doubt that fishermen of that 

 village caught it in the deep water (200 fathoms or more) contiguous to ]\Iisaki. Its 

 unique characters had not been noted by us. 



Unfortunately, I am not yet in possession of the original descrijition of Ilarriotta 

 raJeighana by Messrs. Goode and Bean; but the short description, the extremely 

 elongate muzzle, and the feeble clasi)ers, as well as a comparison of the two figures, 

 leave no doul)t in my own mind that the individuals figured belong to the same genus. 



There can be very little question that they belong to different species. (1) The 

 general shape of the body, (2) the shape and size of the pectoral and ventral fins, 

 (3) the point to w'hich these fins reach when back, (4) the shape and disposition of 

 the dorsal fins, (5) (listril)ution of lateral-line sense system, all seem to point to the 

 specific distinction of Atlantic and Pacific specimens. The name of Ilarriotta ]>acifica 

 will V)e ai)proj)riate to the Jai)anese species. 



I liojie to return to the subject and to give fuller notes at no distant date. The 

 occurrence of this interesting genus in both the Pacific and Atlantic oceans is, however, 

 an interesting fact well worthy of being placed on record as speedily as possible. 



Of this species a few specimens have l)een obtained h\ Professoi' 

 Mitsukuri in deep water ofi' Misaki, These the senior author has 

 examined, l)ut has not minutely described.
