434 BULLETIX 15 3, UNITED STATES NATIONAL MUSEUM 



In the right wing the fourth primary alone is new, while in the 

 left, the inner secondaries, and the eighth (third from outside) 

 primary are new, the remainder of the remiges old. The rectricial 

 molt is likewise peculiar. Both males have replaced the middle 

 pair; the next pair are old, the next pair new, and the rest old. 

 In the female, the tail molt agrees with that of the wing in being 

 different from the males. The middle rectrices are old, the next 

 one on the right side is new, on the left side, old. The rest are of 

 the old plumage. The body molt in all three is very irregular and 

 very slight. The Hawash Kiver specimen is molting the upper 

 tail coverts; the others are not. The irregularity of molt in this 

 hornbill is interesting in connection with Wetmore's observations 

 on that of the Malayan Rhinoplax vigil.^^ A thorough study of the 

 molts of this family should yield interesting results. 



The ground hornbill was observed as follows : Abaya Lakes, 

 March 19, 1 bird ; Gato River, March 29 to May 17, 10 seen ; Bodessa 

 and Sagon River, June 3-6, 2 noted ; and Tertale, June 7-12, 2 seen.

Sclater ^ considers ugandae Berger a synonym of gidfsohalito and 

 recognizes no subspecies of this barbet. In this he is mistaken, as 

 Uganda birds are smaller (shorter wing) and have the yellow and 

 white edges of the remiges noticeably narrower and less conspicuous. 

 Claude Grant ^ writes that the characters of ugandae are not sub- 

 stantiated by the British Museum series, but Van Someren ^ writes
