und wenn es ein junger Yogel war — wie Salvin 

 meint, ohne ihii gesehen zu liaben — so wiirdc das zu 

 kleine Fliigelmass dadnrch erklarlicL. Da jedoch der Name 

 nicht absolut sicher ist, nehnien wir besser Mathews' neuen 

 Namen an ; auch Stiicke von Sendai Bai werden die Frage 

 kaum entscheiden konnen, da dort die Art nur eine zufiillige 

 Erscheinung sein diirfte " (Vog. pal. Fauna^ ir. p. 1416). 



Dr. Hartert^s opinion, I think, is quite correct, and the 

 usual habitat of the bird is off the coast of Sagami Sea, where 

 the type specimen of 0. oiostorii was obtainetl. 



A specimen obtained at Torishima in 1891, and now pre- 

 served in the Science College Museum in Tokyo, has 

 been examined by me. It agrees well with the Sagami 

 specimens before me. It was identified by Dr. Stejneger as 

 O.fidu/inosa (Proc. U.S. Nat. Mus. xvi. 1893, p. 620). 



Viscount Matsudaira has sent me an additional thirteen 

 specimens from his own collection. Tiiere is no great indi- 

 vidual variation except that the two newly-moulted birds 

 (probably young ones) are rather darker grey than sooty, 

 as in the other somewhat abraded specimens. One of them 

 has its bill less stout and much like that of true 0. markhami. 

 Moreover, these two birds have 'their wings decidedly 

 shorter than in the others, but the length of tarsus and toes 

 of the two specimens are equal to the length of those of true 

 0. owstoni. I am inclined to think that these two birds are 

 not 0. markhami, but the young (probably the bird of the 

 second year) of 0. oivstoni. Another specimen, I suppose, 

 is a young of the year. It has the mantle-feathers fringed 

 with pale colour. 



There is a variation of the wing-formula of these birds 

 as follows : — 



The first primary longer than the fourth ... 5 examples. 

 „ ,, „ about equal to the fourth 4 „ 



„ „ „ shorter than the fourth ... 4 „ 



The length of tarsus in true 0. markhami is only 24 mm. 

 No females v.ere obtained by Viscount Matsudaira.
