54 Mr. C. H. B. Grant on a Collection of 



It is worthy of note that, so far as I can learn, the exact 

 breeding-place of this bird is not known, and the eggs have 

 not yet been described. The eggs in the British Museum, 

 collected by Holland in the Argentine and recorded in the 

 Cat. of Birds' Eggs (E. Gates), vol. v. 1901, p. 207, pi. xvi. 

 fig. 5, are without doubt those of L. maculipennis Licht, (Verz. 

 Doubl. 1823, p. 83: Monte Video); and I should not be 

 surprised to learn that the breeding- place of this species 

 was not in South America, especially as ray own observations 

 in the Argentine showed that L. cirrhocephalus left during 

 the breeding-season [cf. Ibis, 1911, p. 475). 



On going through the dated adults in the National Col- 

 lection the following shows the months during which they 

 occur on the two continents : — Ajrica : January, February, 

 March, May, June, July, August, November and December. 

 South America : March, April, May, July, September, 

 November and December. 



This certainly seems to point to the bird being found 

 throughout the year on both continents and is in contra- 

 diction to my own observation quoted above. 



Sir Frederick Jackson says that this gull breeds com- 

 monly on Lake Naivasha, but I have not been able to 

 examine eggs in support of this.

Total length in flesh : 11^ inches. Wing : 195 mm. 



This bird is in quite good dress, very little worn. The 

 white underparts are stained with sandy, due to the nature 

 of the ground on which the bird was shot. 



As regards S. latifrons Reichenow (Ornith. Centralb. 1881, 

 p. 79: Berdera, B. Juba), I cannot, with the specimens before 

 me, see any dift'erence either in the white band of the fore- 

 head or in general colour between western and eastern birds.
