Two of" tlie three eggs are almost identical, hiit the third 

 slightly differs. The ground-colour is pure white and slightly 

 glossy, with medium-sized spots and minute specks of blackish 

 brown and smoky grey forming an interrupted zone round 

 the larger end ; a few of these spots are scattered over the 

 smaller end of the shell. Two are ovate in shape, but the 

 third is a little more elongated. They measure lo'Oxll'o 

 to 15-8 X 11-0 mm. [G. H. G.]

The egg figured was one of a clutch of three taken by 

 Mr. A. Duncan of Johannesburg. The three eggs were so 

 much alike that it was not thought necessary to figure more 

 than one of the clutch. The discovery has already been 

 shortly noticed in this Journal {q.v. vol. i. no. 1, }). 3.5). 

 Mr. Duncan now writes : "I found these eggs on October 26th, 

 ] 902, in the range of hills beyond Orange Grove, about 

 four miles from Johannesburg. The birds had nested in an 

 old Swallow's nost on the face of a rock about ten feet from 

 the crround. The nest was formed of small twios lined with 

 hair, small roots, and some pieces of twine, and was held 

 together with spiders' webs. I also found another nest a 

 week afterwards, also situated in an old Swallow's nest placed 

 in a prospecting tunnel about ten yards from the entrance ; 

 this nest contained three fully-fledged young — two male and 

 one female. 1 mention the sexes as the young males had the 

 ■white patch on the wings as in the adult male, and the female 

 corresponded with the adult female." 



Mr. Duncan's account agrees with that of Major Sparrow, 

 who took some six nests in Natal, as described in this Journal, 

 vol. i. no. 1, p. 14. So far as can be ascertained no other 

 precise descriptions of the nidification or eggs of this species 

 have been published. 



The three eggs of the White-shouldered Bush-Chat do 

 not vary very nmch inter se. They are of a bluish-white 

 ground-colour, very slightly glossed, and have small blotches 

 and minute spots of lavender-grey and huffish brick-colour,
