remarks regarding tlieir difierent notes and the nature of 

 the country in which they were procured. 



He said : — " My experience of the different species of 

 Cisticola teaches me that it is always far more difficult to 

 separate the species Avhen they are dead and laid out in rows, 

 no matter how large the series, than when the birds are seen 

 alive, especially if one can hear their notes. In the case of 

 C. belli and C. woosnami,\\h\c\\ have just been described, the 

 difference between their notes is very striking, and each has 

 a song unlike that of any other species of the genus with 

 which I am acquainted. 



" The nearest ally of C. belli is C. chubhi, Sharpe, which 

 was originally described from Mt. Elgou, and is met with 

 among the elephant-grass on Ruwenzori at an elevation of 

 from 5000 to 7000 feet. It is a vei'y common bird and its 

 loud note is one of the first to attract attention. 



" C. belli is not found on the mountains and was only met 

 with in the dense papyrus-swamps along the shores of the 

 lakes or courses of streams. Its note is totally diflferent from 

 that of C. chubbi, and is best described as resembling the 

 latter part of the song of the Yellow Hammer. 



" The other new species, C. woosnami, which is nearest to 

 C. rvfopileaia, Reich., is found among the dry acacia-couutry, 

 on the plains around the south end of the range. Like 

 C. chubhi it is a very common bird and has a most striking 

 long-drawn reeling note, which is usually uttered from the 

 top of an acacia-tree. 



" C. rufopileata was not obtained anywhere in this region, 

 but was met with in the open clearings of the Congo forest, 

 150 miles west of Ruwenzori. Its note is most like that of 

 C. chubbi, but is not so loud. 



" I am certainly of opinion that these marked differences 

 in habits, notes, and locality, coupled with the differences 

 Mr. Ogilvie-Grant has just pointed out, fully justify the 

 separation of these two new forms."
