The specimen collected (only the head) has a larger bill than any 

 of a series from Kenya Colony. The culmen in this bird measures 

 316 millimeters and at the base the bill is 80 millimeters deep. The 

 largest Kenya measurement is as follows : Culmen 310 millimeters, 

 depth of bill at base, 79 millimeters. 



Mearns observed the marabou stork in the following localities 

 during the course of the expedition. A few were seen between Bilan 

 and Sadi Malka, none at Dire Daoua, although he was told of their 

 presence near the latter city. At Sadi Malka the species was rare, 

 but on the upper Hawash River it was seen everywhere in flocks of 

 50 or more, usually about native settlements. At Loco, March 15-17, 

 2 were seen ; Abaya Lakes, March 18-26, 136 birds noted ; near Gar- 

 dula, March 26-29, 10 seen; Gato River, March 29 to May 17, 100

IBIS IBIS (Linnaeus) 



Tantalus ibis Linnaeus, Syst. Nat., ed. 12, vol. 1, p. 241, 1766: Egypt. 



Wood ibises were met with in two localities by the Frick expedi- 

 tion — North or " Black " Lake Abaya, March 18, where 12 birds 

 were seen, and on Lake Rudolf, July 5-8, where 1,000 were observed. 

 No specimens were taken in either place. Neumann *^ writes that 

 this stork appears to be less common in northeastern Africa than in 

 Kenya Colony and Tanganyika Territory.
