available specimens of Terpsiphone afflnis procera., a form appar- 

 ently restricted to the island of Simalur. Comparison of our series 

 with specimens of Terpsiphone affinis nicohanca, from the Nicobar 

 Islands, shows, however, that the difference in the color of the head, 

 mentioned by Doctor Richmond in the original description of his 

 Tchitrea procera^ is not a constant nor a very important character. 

 In most specimens of the latter the metallic sheen on the head is very 

 nearly as greenish as in Terpsiphone afflnis nicoharica, though in one 

 or two it is appreciably more bluish. There is, however, an average 

 difference in the darker, duller appearance of the pileum and throat 

 in Terpsiphone affinis procera., which has also a shorter wing, and is, 

 of course, a recognizable form, though, by reason of individual in- 

 tergradation with Terpsiphone afflnis nicoharica^ a subspecies of 

 Terpsiphone afflnis., not a distinct species.
