1910.] THE BIRDS OF HAINAN. 5J3 



C. chinensis, but it is much more closely allied to C.jefferyi Sharpe, 

 from Borneo, and to C. robinsoni Ogilvie-Grant, from the Malay- 

 Peninsula.

«. <3 . Five-Finger Mts. 9th November. 



b. 2 • Seven-Finger Mts. 15th November. 



Hainan examples of this Magpie appear to be somewhat 

 smaller than Chinese birds. In six specimens the wing measures 

 less than 5 inches, but in a seventh (a male) it attains a length of 

 5 - 4 inches. Three specimens have the middle pair of tail-feathers 

 black to the base, and three show traces of grey, while in the 

 seventh the basal half of the feathers is grey, as in the Formosan 

 species, D.formosce Swinhoe. Chinese examples may generally be 

 distinguished from Hainan birds by their purer white upper tail- 

 coverts, but these characters seem too variable to warrant the 

 separation of the Hainan birds from typical I). sinensis. In certain 

 respects they are intermediate between the Chinese and Formosan 

 forms, the latter being always characterized by their greyer upper 

 tail-coverts and the grey basal half of the middle pair of tail- 

 feathers. Dr. Hartert has separated this bird as a subspecies 

 under the name D. s. insulce. 



8. ACRIDOTHERES CRISTATELLUS (Gmel.).

a, b. <$ 2 • Seven-Finger Mts. 16th November. 



Examples of this Starling from Hainan appear on the whole to 

 be somewhat smaller than those from China, and have perhaps 

 rather less white on the basal half of the primary quills. In six 

 Hainan examples the wing-measurement varies from 4*8 to 

 5 inches, while in a seventh specimen it measures 5 - 25 inches. 

 Dr. Hartert regards this bird as distinct and has named it 

 A. c. brevijjennis.
