giveu (Orn. Jahrb. xxi. p. 130) it appears, however, that 

 Corsiean birds are, as uiight be expected, shorter-winged than 

 continental specimens, and may eventually be separated on 

 that account. Eggs, 4-5, usually laid about mid-May, but 

 on one occasion by May 1. 



15. Cardtjelis carduelis tschusii Arrigoni. Sardinian 

 Goldfinch. 



Carduelis carduelis tschusii Arrigoni, Avicula, 1902, 

 p. 104 (Sardinia). 



Local name : Cardellina. This small, dark, short-winged, 

 and slender-billed race is common to Corsica and Sardinia, 

 and is an extremely numerous resident in all the low ground 

 and foot-hills, but appears not to extend its range to any 

 height in the mountains. Probably several broods are 

 reared during the season, as Whitehead in his MSS. notes 

 records having found young at the beginning of April. I 

 met with one nest with young on May 11, but found many 

 with fresh eggs in the latter part of May, and Whitehead 

 took fresh eggs as late as June 10. The beautiful little nest 

 is often placed in the olive, ilex, and cork-oak trees near the 

 villages, and is distinguishable at a glance from that of the 

 Serin by the white down lining, which replaces the thick 

 lining of hair found in the rather smaller nest of the latter 

 bird. The eggs, however, vary in size a good deal and are 

 often indistinguishable, tho\igh those of the Goldfinch are 

 usually longer. Average size of 42 Corsiean eggs, 16"81 X 

 12-79 mm.; max. 18-2 x 13*2 and 17'9xl3-5, min. 15-6 x 

 13-1 and 15 8x12. 



16. Carduelis spinus (L.). Siskin. 



Whitehead met with this species in the early spring of 

 1884 : a male was shot by him on Feb. 4, and some indi- 

 viduals stayed till nearly the end of March.
