affinity of these two districts has been ascertained for a long 

 time; and it would become still more apparent if regard had 

 been had not only to species (some of which have a very wide 

 range) but also to genera — and, secondly, if the marine fauna of 

 Western North America had been drawn within your present 

 researches. 



Of course you are aware that a large proportion of the ter- 

 restrial animals of Northern Japan are European types. 



I remain, yours very truly

Note on a New Species of Japanese Brachiopoda. By Thomas 

 Davidson. Communicated by J. Gtwyn Jeffreys, Esq., 

 LL.D., E.E.S., E.L.S. 



[Eead January 15, 1874.] 



In the Proceedings of the Zoological Society of London for 

 April 1871, 1 described and illustrated all the species of Brachio- 

 poda (twenty in number) that had been procured from the 

 Japanese waters. 



Since then Dr. C. E. Lischke obtained from the Bay of Jedo 

 several examples of a coppery-coloured and green Lingula, 

 approaching in size and character to Lingula smaragdina, Adams, 

 a species common to the China sea, and which will before long 

 be described in that naturalist's work ' Japoniacks Musei Con- 

 chilica.' 



In 1872 Captain St. John, of Her Majesty's Ship ' Sylvia,' 

 dredged five or six species of Brachiopoda iii North Japan, 

 namely : — Terehratella Coreanica, Adams & Eeeves, 48 fathoms ; 

 T, frontalis, Middendorff, 35 fathoms ; Laqueus rubella, Sow., 35 

 fathoms ; Waldheimia Grayii, Dav., and its var. transversa, 35 

 fathoms ; Bhynchonella psittacea, Grmelin, 35 fathoms. 



We are therefore indebted to Captain St. John for the know- 

 ledge of one additional species in the Japanese waters, viz. Tere- 

 hratella frontalis, Middendorff; and it is interesting to add that 

 during the year 1873 Mr. Dall has dredged several living speci- 

 mens and many dead ones of his rare species at Atka Island, of 

 the Aleutian Chain, but originally described from the Ochotsk 

 Sea. He informs me also by letter that its range in the island
