60 LT. C. G. FINCH-DAVIES ON THE 



68. Lophoceros monteiri — Monteiro's Hornbill. Not 

 nncomnion round Okanjande. Usually to be found in pairs. 

 It has a loud call, and looks very strange as it gives vent to 

 it, bobl)ing up and down in a most ludicrous manner. When 

 I left Okanjande in May this species was common, but since 

 my return in September 1 have not seen a single individual. 



G9. Lophoceros leuconielas — Yellow-billed Hornbill. 

 I did not meet with this species till May, wdien, just before I 

 left Okanjande, I secured a single specimen. I then went to 

 Outjo, where I found it to be the common Hornbill of the 

 district, going about in flocks of six or seven, following each 

 other in single file, from tree to tree, with a di})ping flight. 

 On my return to Okanjande in September I found it had 

 become quite common there. Its note almost exactly 

 resembles that of the next species. 



70. Lophoceros damarensis — Damara Hornbill. 

 This species is not common, and I have met wath it only 

 along the banks of rivers, where it frequents the large camel- 

 thorn trees. Mr. Austin Roberts, of the Transvaal Museum, 

 informs me that he has written an article on the status of 

 this species and erythror hy nchus, so I will not say much 

 on that question here. But I might, however, point out that 

 some specimens shot locally might be damarensis, others 

 again ery throrhynchus, and some examples are inter- 

 mediate. AVhile at Otavifontein the form appeared to be 

 erythrorhynchus only. There it was very common, and 

 to be seen in large numbers frequenting the slaughter places 

 and oft'al heaps, presumably in search of insects. At times 

 it ieed^ a lot on the around, dio-oino- with its bill amongst 

 the debris of decayed leaves, etc. The notes of all three of 

 the s[)ecies seen in this country are very similar. 



71. Dicrocercus hirundineus — Swallow-tailed Bee- 

 eater. I found this species common at Okanjande and Outjo 

 from March to July, but since my return to* the former 

 place I have not seen a single exam})le. It is usually to be 

 seen in pairs, sitting on some convenient perch, from thence 

 flying off to seize some passing insect.
