Rev. F. C. R. Jourdain on the 
given (Orn. Jahrb. xxi. p. 130) it appears, however, that 
Corsican birds are, as might 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.

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, though those of the Goldfinch are 
usually longer. Average size of 42 Corsican eggs, 16*81 X 
12*79 mm.; max. 18*2x13*2 and 17*9x13*5, min. 15*6 x 
13*1 and 15 8 x 12. 
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. 
17. Carduelis cannabina mediterranea (Tschusi). 
Mediterranean Linnet. 
Acanthis cannabina mediterranea Tschusi, Ornith. Jahrbuch, 
xiv. p. 139 (1903—Dalmatia). 
Linnets are common in winter in Corsica, and a few pairs
