 6. — Phyllastrephus indicator leucurus. 



Tricophorus letictirus Cassin, Proc. Ac. Se. Philad., 1855, p. 328 : 

 St. Pauls River, Libéria. 



Distinguishing characters. — Differs from Ph. i. îissheri in 

 having the upper-parts miich darker olive, under-parts much 

 darker, grever, and with very little olive-wash. Under tail-coverts 

 palest bnfF, ahnost white. 



Range. — Libéria. 



Observation. — The extent of the range of this and the other 

 West African forms cannot be determined until larger séries are 

 available. It mav then be found necessary to reduce certain of the 

 races which hâve been described. The descriptions given bv Rei- 

 CHENOw of the races which be described seem to me to be very 

 unsatisfactory. 



Ixonotus guttatus. 



Ixonotns guttahis Verr, Rev. Mag. Zool., 1851, p. 306. — Tvpe 

 locality : Gaboon.) 



Mr LowE shot seven examples in January and Februarv 1920 at 

 Iju water works. 



There are three other spécimens of the Spotted Bnlbul in the 

 British Muséum from Southern Nigeria obtained bv P. A. Tai,bot 

 at Oban and Nsan. 



Range. — Reichenow gives the range of this Bulbul as Libéria 

 to Loango. In the British Muséum we hâve spécimens from the 

 Gold Coast, Northern Nigeria, Cameroon, Gaboon and the North 

 Belgian Congo as far East as Mawambi. 



There are no races of this bird. Examples from the Gold Coast 

 and the East Congo forest being indistinguishable. 



There is another member of the genus in West Africa» 

 /. landanae which is not represented in the British Muséum. 

 It was described by Oustalet from Landana where it apparently 

 lives side by side with I. guttatus.
