298 REVIEW OF JAPANESE BIRDS. 



Mr. Collie ou the " Blossom " was the first to collect this species, 

 which has ouly been fouud ou Bouiushima. He remarks that several 

 were seen frequenting the rocks ou the sea-shore, and Von Kittlitz, who 

 shortlj' after visited the same place and collected specimens, says : 

 "Bather common, keeping itself concealed during day-time in the lava 

 caves at the shore and iu the neighboriug dense bushes." The same au- 

 thor, iu his " Denkwiirdigh. eiuer Keise," &g., I. c, adds that " the single 

 rough call-notes, which are also heard during the day-time, have some 

 resemblance to the cry of the raven."

Bogdauow has recently (i. c.) described the bird from the Amur and 

 Ussuri as distinct under the name of B. sckrencJcii. Judging from my 

 material I think he is right iu regarding the northern form as separable 

 from the Australian representative, and I refer the Japanese specimens 

 without hesitation to the continental form, but I cauuot regard either 

 of these forms otherwise than subspecies of the origiual B. javanicus 

 (Horsf.), nor can I adopt Bogdanow's name, iu view of the fact that 

 Von Schrenck himself has intimated a subspecific appellation for the 

 bird afterwards named in his honor. 



It is a curious fact that B. javanicm and its subspecies are much 

 more like the South American B. striatus (Ltnn.), thau the North 

 American B. virescens (LiNN.), but the South American form is easily 

 distinguished by the rich rufous spots on the fore neck. 



B. amurensis shares the thick bill (by which it chiefly diflers from 

 the typical B. javanicm) with the Australian B. macrorlujnclms. Bog- 

 danow states that its bill is even much thicker (" rostro ad basin sesqui 

 crassiore"), but I cannot help thinking that he has had an unusually 

 slender billed B. macrorhynchus for compar ison, for the three specimens
