188 Mr. O. Salvia's Five Months' Birds' -nesting 



full feather, the same inequality in size subsisting between the 

 two. They were, doubtless, male and female. Unfortunately 

 the male died during the journey between Marseilles and Paris, 

 and we had no means at hand for preserving it. The female is 

 now at Catton. From this female it would appear that all 

 Mr. Gumey's birds were females, as all corresponded in size ; and 

 I am also led to the conclusion that the two skins I possess, 

 from one of which the accompanying figure is taken, are also 

 females, as Mr. Gurney kindly compared them with his living 

 examples, and in point of size they presented no appreciable 

 difference. I mention this, as my two skins are m ',rked male and 

 female ; but I was evidently mistaken in one or other, as both 

 are as nearly as possible the same size, or, if anything, the one 

 marked male is the larger of the two. From the stomach of 

 both these specimens I took examples of a large species of Enio- 

 zoon, but unfortunately did not preserve them. I am indebted 

 to Mr, Alfred Newton for the quotations which I have given 

 above respecting this bird, and also for the probable references 

 which I subjoin : —
