Type of the species : No. 3571. ? . Bitye, River Ja, 

 7th April, 1909. 



Obs. Though this species seems so closely allied to Melig- 

 nomon zenkeri that it must be considered as a second 

 species of that genus, the generic diagnosis of Reichenow 

 will have to be altered for its reception, as only three, instead 

 of four, middle pairs of rectrices are alike in length, and 

 the three, instead of the two, outer pairs are shorter and 

 graduated. Moreover, the outermost rectrices are only 

 about half as long as the middle ones, while in M. zenkeri 

 they are comparatively but little shorter. 



This bird is much larger and more robustly built than 

 M. zenkeri, and has the bill and legs stouter, though the 

 former is not blunt as in Indicator. The body is remarkably 

 depressed, the keel of the sternum being shallow. 



Parisoma holospodium, sp. n.

 colour; underparts lighter, becoming whitish on the throat,

Obs. Another male specimen (No. 3696) is smaller than 

 the above-mentioned male and about the size of the female. 



Compared with Muscicapa ccerulescens and M. lugens, this 

 species is smaller and more slightly built; it has likewise 

 a more slender bill, and is darker than either. The tail is 

 not short, as in Mr. Ogilvie-Grant's M. brevicauda (cf. Ibis, 

 1908, p. 308), and there is no white about the lores or eyes.
