words, the latter has a much more rounded wiuj^- than the former. It 

 also Las a much longer and more rounded tail, as well as a longer 

 tarsus. The bill, however, is of the same size in both forms. 



In regard to color the characters previously given are not only con- 

 firmed, but the actual comparison of specimens "furnishes additional 

 important ones. The rufous color of the upper parts is much brighter 

 in I. Jcomadori, being of a vivid rufous orange, against the deep orange 

 rufous of I. namiyei. The supposed difference in the coloration of 

 the under tail-coverts is also confirmed, they being suffused with apale 

 cinnamon-rufous in I. namiyei., while in I. Jcomadori they are pure white. 

 The specimen of the latter before me has the black feathers of the fore 

 neck narrowly margined with white, a feature apparently attributable 

 to season, ajid the pale color of the under mandible may possibly be 

 due to the same cause. 



The specimen of I. Icomadori measures as follows : 



$ a,d. {ToMo Ediicat. 3his. Yayeyama Island. J. NisM coll.). — Wing, 

 TG'nm J tail-feathers, 45'"'" ; exposed culmen, 14""" ; tarsus, 26™"' ; middle 

 toe, with claw, 22"'™. 



My surmise (Zeitsch. Ges. Oruith., 1887, p. — ) that the Icoturus, re- 

 ported by Mr. Pryer to occur on the northern group of the Liu Kiu 

 Archipelago, might possibly be the true 7. Icomadori was evidently not 

 a happy one, as it turns out that it is the most southern group which is 

 inhabited by this species. But, then, what is the bird of the northern 

 group ? May we possibly expect a third species from there ? 



Turdus pallidus Gmel. 



A young male, with whitish tips to the great wing-coverts, collected 

 by Mr. Namiye at Napa, Okinawa Shima, March 4, 1886, and an adult 

 female, collected by Mr. J. Nishi on Yayeyama Island, both agreeing 

 with specimens from Japan proper, are in the collection. The latter is 

 now U. S. Nat. Mus. No. 110970. The former measures as follows : 



Wing, 128"^'"; tail-feathers, 91""" ; exposed culmen, 20'"'"; tarsus, 32"""; 

 middle toe, with claw, 31'""". Total length, according to Mr. Namiye, 

 250'"'". 



Turdus chrysolaus Temm. 



A single specimen, adult male, is before us, collected by Mr. Namiye 

 on March 19, 1886, at Nagogushiku, Liu Kiu. It is somewhat aberrant, 

 as the wing-formula is nearly that of T. obscurus, second primary being 

 somewhat longer than fifth. The bill is also rather small, but the 

 under wing-coverts and axillaries are as gray as in typical specimens. 

 It measures as follows : 



Wing, 124'"'" ; tail-feathers, 94'""' ; exposed culmen, 17""" ; tarsus, 

 32mm. middle toe, with claw, 30"^™. Total length, according to Mr. 

 Namiye, 240'"'". 



Monticola soUtaria (Mlxl.). . 



A bird in the gray plumage was collected by Mr. Tasaki in the 

 "northern part of Liu Kiu."
