5. (162) Janthoenas janthina (Temm.)- 



$ ad, Okadamura, Osbima, April 16, 1887 (No. 111651); 9 ad.., 

 ISliisbima, April 23, 1887 (No. 111655) ; 9 ad., Kodzusbiina, April 26, 

 1886 (No. 111656). It was fouud ou all the islands, but particularly 

 abundant ou Kodzusbima and Niishima. 



All tbree specimens are in excellent plumage, and tbe metallic gloss 

 very brigbt. Tbe male differs sligbtly from tbe two females by baviug 

 tbe juguluin cbietly greenisb aud not lilac, by tbe edges to tbe smaller 

 wiug-coverts being greenisb and not purijlisb, and by tbe rump being 

 more bronzy and less blnisb puri)le. My material is not sufficient to 

 decide, bowever, wbetber tbese differences are due to sex, age, or indi- 

 vidual variation. I am most inclined to think that they are due to age. 

 Naturalists in tlie field should try to solve the problem. 



Tbe three specimens measure as follows : 



6. (323) Falco peregrinu.s Tunst. 



Obtained at Elachijosbitna. No specimen sent. 



7. (ITO) Yungipicus kizuki (Te.m.m.). 



9 ad., Miyakeshima, May 3, 1887. According to Namiye found on 

 Miyakesbima only. 



In bis letter to me Mr. Namiye remarks that he thinks that the bills 

 of the birds which he collected on this island are larger and stronger 

 than those of the birds inhabiting Hondo. I am unable, however, to 

 isee any difference between the specimen which he sends and typical Y. 

 JcisuM and the measurements given below, as compared with the table 

 included in my review of the Japanese Woodpeckers (Proc, U. S. Nat. 

 Mils., IX, 18S6, p. 122), will demonstrate this assertion. I will suggest 

 tbe probability that Mr. Namiye has compared the Miyakeshima birds, 

 which are in breeding plumage and have the nasal tufts considerably 

 abraded, with winter specimeus from Hondo, in which the nasal feath. 

 ers cover the greater part of tbe base. Such a comparison would show 

 an apparent difference in the size of the bill. 



In coloration the example sent agrees minutely with Nagasaki speci- 

 mens. 



It measures as follows: Wing, 83™'"; tail-feathers, 46'"™; exposed 

 culmen, 14™™; tarsus, 15™™; exterior anterior toe, without claw, 10.5""™. 

 Total length, " 145™™."
