94 Mr. N. Kiiroda on the Birds of [Ibis, 



Mr. La Touche's measurements o£ the wing o£ the two 

 forms are as follows : — 

 M. solitaria magna, 



8 S • 4-^-5-b5in. = 122-127-5 mm. 

 4 ? : 4-62-4-85in.= 117-122-5 mm. 

 " The second primary is between the fifth and sixth.^' 

 M. solitaria philippensis = manila. 

 13 S ■ 4-5-4-76 in. ==114-120-5 mm. 



7 ? : 4-47-4-6 in. = 112-5-llG-5 mm. 

 " The second primary is either between the fourth and 

 fifth, or equal to or just below the fifth." 



The length of wing in the new form {latoueliei) is shorter 

 than that of magna, as given by Mr. La Touche (Bull. B. 0. 0. 

 xl. 1920, p. 97). I therefore sent the measurements of 

 the new form to Mr. La Touche, then at Mengtsz, Yunnan, 

 for comments. He has kindly written to me as follows : — 

 "I think your Tshushima and Iki Rock-Thrushes are the 

 Chinese Petrophila manila. The measurements are those 

 of Cvhinwangtao birds." But I have compared them with two 

 Formosan examples of M. solitaria philippensis — manila, and 

 have found that the Formosan bird is much smaller and 

 shorter in bill ! The Tsushima and Iki birds before me are 

 apparently intermediate forms between true magna of Japan 

 Y>vopev undphilippensis h'onx Formosa. In my Tsushima and 

 Iki examples the second primary is between the fifth and 

 sixth, except that one female has its second primary between 

 the fourth and fifth. In one Hondo example the second 

 j)rimary is between the fourth and fit'tii ! The new form is 

 nearer to magna than io phiUppensis. 



The subspecific name is given in honour of Mr. J. D. D. 

 La Touche. 



Dr. Ijima (p. 106), Seebohm (Ibis, 1892, p. 89), and 

 Mr. Clark (/. c. p. 175) reported the Rock-Thrush from 

 Tsushima. 



*95. Calliope calliope (Pallas). 



A male was obtained by Mr. Teraoka at Kuroda, Tsushima, 

 Oct. 25.
