308 Letters, Extracts, and Notes. [Ibis, 



Colonel Verner informs me that since 1911 he has from 

 time to time noted Blackbirds' nests in Spain with four eggs 

 but none with five. 



It is consequently obvious that nests containing more 

 than tliree eggs are by no means unusual nowadays, but it 

 is certainly curious that this should be the case now and not 

 ten years and more ago. 



Is it possible that the Spanish Blackbird has become more 

 prolific for some reason unknown? 



Climate, food, and vegetation cannot have altered appre- 

 ciably, but the number of those interested in Spanish oology 

 has undoubtedly increased since those days and more nests 

 are probably examined in consequence.

Dear Sir, — I enclose the following Erratum : — 



In 'The Ibis,' October 1917, p. 584 (T. Carter, "On the 

 Birds of Dirk Hartog Island and Peron Peninsula ''), for 

 Lamprococcyx plogosus curteri (Western Bronze C^uckoo) 

 read Neochalcites basalis ivyndharni (Western Narrow- 

 billed Bronze Cuckoo). 



The two specimens of the above bird, basalis, and the bulk 

 of the collections obtained on Diik Hartog Island in 1916 

 were left in the care of the Perth Museum in West Australia 

 until quite recently, on account of marine risks, and were 

 only received here last week. 



Upon checking them over, I found I hat both the skins 



are labelled basalis.
