I tliiiik that tlic late Mr. Seebohm was in error when he 

 attributed these red eggs generally to L. glaucus ; at any 

 rate, 1 was told last year that this species had ceased to 

 breed at Vardo for some time, yet red eggs are still obtained 

 there.

Sirs, — In reply to your enquiry, I have in my collection 

 eggs of Scaphidurus ater ( = Cassidix oryzivorus) found in 

 nests of Cassicus persicus. I have not yet published any- 

 thing on this subject, but propose to put a notice of this 

 new instance of parasitism in birds in the ' Journal fiir 

 Ornithologie.^ 



The eggs that I possess were obtained near Para, Brazil, 

 by Mr. A. Schulz. This collector found amongst partially 

 incubated eggs of Cassicus persicus some that were larger 

 in size and different in shape, and observed that females of 

 Cassidix oryziimrus entered the nests of the Cassicus. 

 Having shot a female of Cassidix while flying into a nest of 

 the Cassicus, he found in its oviduct a mature egg resembling 

 the larger eggs met with in the nests of the Cassicus. This 

 egg, broken, is now in my collection. 



I am. 



Yours &c.,

 We trust that our excellent correspondent at Para, Dr. Goeldi, 

 will turn his attention to the subject. — Edd.] 



Sirs, — So far as I am aware, Mach(BrhampJms ahinus, 

 Westerm., has not yet been recorded from Sumatra. A pair
