The numerous specimens, 19 in all, from the Okinawa group (i. e., 

 Izena, Yagachi and Okinawashima), contain a number of those in which the 

 bill is much shorter than usual The culmen may be only 31mm. long and 

 sometimes even 28mm , whereas in Hondo specimens it rarely, if ever, 

 falls short of 35mm In comparison with Hondo specimens I further notice 

 that the wing is on the average slightly shorter, that the general coloration 

 of plumage is somewhat duller, that the dingy color of breast in immature 

 birds is much darker and that the reddish of the lower mandible in females 

 is of a deeper red tone
