wild state*, but in Southern Japan it breeds on the mountains and 

 winters in the plains. There is an cxarajile in the Pryer collection 

 from Yokohama, and I have four examples from Nagasaki, for which 

 I am indebted to the kindness of Mr. Ringer. It breeds on the 

 Seven Islands (Stejnegcr, Pi'oc. United States Nat. Mus, 1887, 

 p. 486). L'Abbe David found it at Pekin in April, and at Fokieniii 

 November, so that it is probably a resident in North China as well as 

 in Japan. 



12, EEITHACUS NAMIYEI. 

 (STEJNEGER'S ROBIN.) 



Icoturus namiyei, Stejneger, Proc. United States Nat. Mus. 188G, p. G4o. 



The adult male of Stejneger's Robin has the black chin and throat 

 of Temminck's Robin, but its under wing-coverts, flanks, and axil- 

 laries are grey as in the female of that species. The female has a 

 brownish-grey breast. 



Stejneger's Robin was described by Dr. Stejneger from an adult 

 male obtained by Mr. Namiye on the mountain of Nagoga- 

 take in Okinawa Shima. There is an example (a female) in the 

 Pryer collection from the same island, which differs from the female 

 of Temminck^s Robin in various characters which are pointed out on 

 the next page. No other examples are known. Erithacus sihilans 

 may be distinguished from both the Japanese species by its resem- 

 blance to Erithacus akahige in the colour of its upper parts. The 

 measurements of the two examples of Stejneger^s Robin are as 

 follows : — Wing from carpal joint, ,^ 2"85 inches, $ 2*75 ; tail, 

 ^ 2*05,? 1"8 ; exposed culmen, cJ'55, ? "5 ; tarsus, ^ 1-15, ? I'l ; 

 middle toe with claw, (^ "2, ? '83 ; gradation of tail ^ "2, ? '15. 



Erithacus komadori, E?ithacus akahige, Erithacus sihilans, Eritha- 

 cus namiyei, and Erithacus rubecula, all belong to the same subgeneric 

 gi'oup of the genus Erithacus. In the concavity of the wing, in the 

 comparative length of the first and second primaries, in the feather- 

 ing of the nostrils, and in the development of the rictal bristles they 

 are almost identical. I cannot therefore admit the validity of 

 Icoturus (Stejneger, Proc. United States Nat. Mus. 1886, p. 613) 

 even as a subgenus. 



* I have an example collected by ]\Ir. Ilenson at Hakodadi on the 28th of June. 

 As its wings are very much abraded and its tail is in moult, I assume it to be an 

 escaped cage-bird.
