the upper parts much paler — bhiish ashy gray, the white streaks on 

 the sides of the head even broader than in stegmanni, and has the 

 white superciliary bands present. Without material to examine, I 

 can not form an opinion as to the validity of angolensis and there- 

 fore tentatively follow Sclater in synonymizing it with this race. 



Granvik ®^ gives the measurements of a series of what he considers 

 suahelicv^ and records 260 millimeters as the maximum wing length. 

 The present adult male from Meru forest exceeds this by 5 milli- 

 meters. I suspect that Granvik's specimens (from Londiani and 

 Mount Elgon, especially those from the latter locality) are not 

 suahelicus^ but steg'manni. 



The Juvenal plumage resembles that of the adult, but young birds 

 have the bill j^ellowish rather than reddish, and without any casque 

 whatever. The ju venal bill color appears to last for about a year. 



As in so many hornbills the wing molt has two centers of origin — 

 the carpal joint, and the third from the outermost primary. The 

 tail molt begins simultaneously with the middle and the outermost 

 pairs of rectrices. 



The crowned hornbill lives in fairly thick bush and around the 

 edges of forests, but it also, although relativel}^ less frequently, occurs 

 in open thornbush country. It appears to be more local than L. 

 erytli(rorliyncKu8 and stays more in higher trees. Erlanger ^* found 

 L. melanoleucos simhelicii^ to be common in the country between 

 Umfudu and Gobwen, and on the island of Gascha, all in southern 

 Somaliland. He collected a juvenal female toward the end of June, 

 but unfortunately does not say whether it was one recently out of the 

 nest or a bird about a year old, so it is impossible to even guess at the 

 breeding season in Somaliland. At Taveta, in southern Kenya 

 Colony, the egg-laying time is in March and April, as I have taken 

 young birds from the nest in the second week of April. 



On August 10, at Meru and Kilindini, Mearns recorded seeing 

 about 200 of these hornbills.
