Ampelis japonicus (Sieb.). 



A male, collected iu Liu Kiu, March 26, 1886 ^U. S. Nat. Mus., No. 

 109477), is identical witli speciraeus from Japan proper. Its total length, 

 as given on the label, is 187'""' ; stretch of wing, 330™"". 



Pericrocotus tegimse, sp. nov. 



DiAGN. — Similar to P. cinereus, but with a very broad and distinct 

 pectoral band of a dark ashy, and without light edges or margins to 

 the remiges and their upper coverts : tertiaries uniform blackish in 

 both webs. 



Type.— U. S. Nat. Mus., No. 109476. 



Habitat. — Liu Kiu, Japan. 



The discovery of this very distinct species of Pericrocotus is most in- 

 teresting, and it affords me great pleasure to dedicate it to the dis- 

 tingaished director of the Educational Museum at Tokio, Mr. S. Tegima, 

 to whose zeal we are indebted for many of our most important acces- 

 sions. 



Two specimens, both males, collected March 11 and 12, 1886, by Mr. 

 Namiye, on Okinawa Shima, agree in every particular and prove beyond 

 doubt the great distinctness of the form. 



Two adult males of the so-called P. cinereus, from the Main Island of 

 Japan, are also in the collection, affordiug good material for comparison 

 with a male collected by Mr. Jankovski iu Ussuri. A specimen of the 

 nearly allied P. cantonensis is also at hand. 



The first result of a careful comparison is, that the male Japanese 

 birds differ from the Ussuri specimen In the following points: 



1. The black on head and upper neck also occupies the upper inter- 

 scapilium, not contrasting so abruptly with the ashy of the back, which, 

 besides, is darker and more blueish. 



2. The bill and feet are proportionately larger.
