Type, ^ ad. Nishisato, Miyako Island, S. Riukiu group, 

 IS.xii. 1921. H. Oriicoll. N. Kuroda Collection, no. 6425. 



Measurements of three males. Exposed culmen 21*5 to 

 23"5 mm. ; wing 129*5 ; tail 122'5 ; tarsus 23. 



The new form is apparently intermediate between M. a. 

 pryeri and M. a, stejnegeri, as is also its geographical range. 

 It is equal in size to M. a. stejnegeri, having paler underparts, 

 but in coloration it is nearly equal to M. a. pryeri, being only 

 a trifle darker. Dr. Hartert considered it probably referable 

 to M. a. stejnegeri of Ishigaki without examining a specimen. 



~t~ Erithacus akahige tanensis, subsp. nov. 



Diagnosis. Similar to E. akahige akahige of Hondo, but 

 distinguished from it by the brensL-band being indistinct and 

 greyish, instead of being well-defined, broad, and blackish. 

 The tips and margins oE all the tail-feathers perceptibly 

 darker. The rufous-red on throat somewhat lighter than in 

 E. a. akaJiige. (One specimen only examined.) 



Type, (^ ad. Nishino-omote, Tauegashima, south of Kia 

 Siu, 22.iii. 1922. H. Orii coll. N. Kuroda Collection, 

 no. 6661. 



Measurements. Exposed culmen 12 mm. ; entire culmen 16 ; 

 wing 74 ; tail 49 ; tarsus 2^. 



I have no specimens from Yakushima, where the subspecies 

 seems to me to occur.

Icoturus komadori subrufuSj subsp. nov. 



Diagnosis. Similar to /. komadori komadori of northern 

 parts of Hill Kiu Islands and Tanegashima, but the upper 

 ])arts from crown to tail as well as wing-coverts throughout 

 paler and lighter, and the outer edges of all the quills 

 including the edges of the primary-coverts and o£ the first 

 primary, and both webs of: the tertiaries orange-rufous instead 

 of brownish like the typical bird, in contrast with the inner 

 webs which are blackish brown. The black frontal band 

 somewhat broader, being 6*5 nmi. in width instead of 

 4-5'5 mm. (One specimen examined.) 



I have compared it with a series of autumn examples of 

 the typical form.
