an old bird and a young one, the latter flying strongly. I 

 have instances of adult and apparently several-months-old 

 young birds of Irrisor eri/tlirorlujnclius being iaken roosting 

 together in what had probably been the nesting-hole, and it 

 seems just possible that something of the same kind may 

 occur in the case of jBacorax. 



XII. — Some Ramhling Notes on Birds, lo'dJi the description 

 of a new species. By Austin Hoberts. 



During the course of the last two years I have had very 

 little time to devote to field work in ornithology ; but there 

 are several notable features of my observations which are 

 worth recording. 



During a holiday spent at Wakerstroom in January, 1912, 

 I was fortunate enough to find a nest of Antlms chloris. 

 The bird flew up from a nest, and, in marking the spot, I did 

 not get a good view of it, so left the eggs undisturbed and 

 came back a couple of hours later. I then got a good view 

 of the bird, followed it, and, when it settled, made quite sure 

 of its identity. The nest was situated under the shelter of a 

 tuft of grass, where it was growing fairly thick, on the steep 

 slope of the hill above the village ; in structure there was 

 nothing unusual about it, and it did not diflPer from that of 

 the commoner species. The eggs are quite distinct from 

 those of other species with which I am acquainted, being in 

 colour exactly like some lightly marked eggs of Macrontjx 

 capensis in the collection of the Transvaal Museum ; but they 

 are much smaller, measuring 20"7 x 15"G, 20"9xl5*5, and 

 21 X 15"5 mm. 



During the following January I spent some considerable 

 time in searching for a nest of Heteronijx riiddi, as the males 

 were particularly noisy at the time and appeared to have 

 nests. One day I noticed a bird fly up, and, in passing 

 a particular spot, utter a peculiar cry ; it flew a little 

 way and then stood regarding my movements suspiciously.
