Remarks. — One male taken by Mjoberg on Pulu Derawan, an 

 island situated between Maratua and the main island of Borneo, 

 is smaller than birds from Maratua, and agrees wholly in color 

 with Bornean examples. 



In six males of horneensis from northern Borneo, the wing varies 

 from 64 to 67; and in one female it is 61. 



Aplonis panayensis suggrandis, subsp. nov. 

 Seven specimens, both sexes, all adult. 



Type. — No. 235888, Museum of Comparative Zoology, adult male, from 

 Maratua Island. Collected March, 1926, by E. Mjoberg. 



Characters.— SiuiilsiT in color to A. p. strigatus (Horsf.), of Tenasserim, Java, 

 Sumatra, and Borneo, but much larger with a much heavier bill. Similar also 

 to A. p. panayensis (Scopoli), of the Philippines, but larger.

Remarks. — Aplonis panayensis is a species of wide distribution 

 in India, Burma, Malay Peninsula, Sumatra, Java, Borneo, the 

 Philippines, and many of the smaller islands. It has a marked 

 tendency to break up into island races whose main criteria are 

 size, color characters being noticeable in only two or three races. 

 The form here described is one of the larger ones. It is larger 

 than afftnis {Calornis affinis A. Hay, Journ. As. Soc. Bengal, vol. 

 15, 1846, p. 36, Tipperah), whose wing measurement, according to 

 Stresemann (Nov. ZooL, vol. 20, 1913, p. 375-377), ranges from 

 103 to 109 (average 105.9), but it is smaller than leptorrhynchus 

 (Aplonis panayensis leptorrhynchus Stresemann, loc. cit., p. 375) 

 from Pini Island, whose wing measurement varies from 111 to 116. 

 To neither of these, of course, can it bear any close genetic rela- 

 tionship. 



Mjoberg took one female on Pulu Derawan Island. This 

 specimen, with a wing of 107, while smaller than examples from 

 Maratua Island, is so much larger in all particulars than birds 

 from Borneo that we refer it to our new form.
