502 On the Nests and Eggs collected in the 



of feathers, and among them a great number of remiges of Pas- 

 serine birds*. 



Eggs (5) : — '7\ X "5 (average); closely freckled with very pale 

 pinkish-red on a white ground^ the last being almost entirely 

 hidden by the markings, so as to have on the whole a strong 

 resemblance to eggs of the British Grasshopper-Warbler {Locus- 

 tella ncBvia). 



3. Nothura perdicaria (Kittl.) ? " Chilian Partridge." 

 Eggs (2): — 2 X 1-52, 1-9 X 1-38. Leaden-brown, very glossy, 



as usual in eggs of the Tinamidce, to which these certainly 

 belong. 



4. Theristicus melanopis (Lath.). "Elizabeth Island. Nov. 

 1867." 



Egg: — 2*71 X 1"86. Dull surface of a pale greenish-white 

 wirh engrained blotches (mostly small) of neutral tint, and some 

 few blotches, spots and specks of deep dull brown ; towards the 

 larger end some hair-like streaks of a lighter shade of the same, 

 and so far having an Ibidineov Plataleine character; but at tirst 

 sight the egg looks as if it might have been laid by an exhausted 

 Gull. 



Dr. Cunningham tells me that be was assured by a man, who 

 was in the habit of making yearly visits to this island to collect 

 eggs, that this belonged to Theristicus; and I see no reason to 

 doubt the determination, for this egg is not irreconcilable with 

 that described by Mr. Darwin (Zool. Voy. Beagle, iii. p. 129). 



5. " Borja Bay. Found on the bare rock. Jan. 2nd, 1868.^' 

 Egg : — 2*41 X 1*65. White, sparsely marked with a few well- 

 defined blotches, spots, and specks of two shades of brown (the 

 deepest almost black), and of lavender-grey (the lightest hardly 

 visible) . This is possibly the egg of an Hcematvpus ; but it very 

 much resembles the eggs of some of the larger Sternince — of the 

 so-called genera Thalasseus and Hydroprogne, for example. 



6. " Tern. Elizabeth Island. Nov. 1867." 



Egg: — 2'21 X 1'57. White or pale ^ci;eam -colour with nor- 



* Some of these feathers have been identified by M. J«les Verreaux as 

 belonging to Asttir pileatus, Noctua ciinicularia, a Dipfopterus, a Sycalis, 

 Tanagra striata, a Geositta, one of the Tinamtda and Porzana albigularis.
