is dull white, faintly tinged with blue, and the patch below is very large and pale orange-bay in colour ; 

 another female, shot by Mr. Alston from the nest on the Fillefjeld, has no trace of blue or bay on the throat, 

 but the chin and upper part of the throat are white, and there is a broad blackish brown band across the 

 breast. Mr. F. Bond has lent me a specimen from Sweden, obtained by Mr. Wheelwright, which is in a 

 peculiar plumage, being precisely similar to the ordinary adult male of C. suecica, except that the bay breast- 

 spot has a narrow white border round it; and I can only account for this peculiarity in its plumage by 

 supposing that it is a hybrid between the two species, as it is well known that many distinct though closely 

 allied forms will occasionally interbreed. 



Lapland. I have one specimen, an adult male, forwarded to me by Mr. Heikel, from Rovaniemi-Lapland, 

 which agrees with Swedish examples, but has the bay breast-spot very large and bright in colour. 



Finland. A single adult male, shot by myself, early in May, near Uleaborg, agrees precisely with the 

 specimen from Rovaniemi. 



Russia. Two males in my collection, one from Mezen and the other from Archangel, closely resemble 

 the specimen from Rovaniemi ; and a female, shot on the 2nd July at Mezen, is precisely like the female shot 

 in Finmark by Mr. Collett. Two from the South-eastern Ural, an adult male and a very young bird, agree 

 also with Scandinavian specimens. 



Germany. In a considerable series from various parts of Germany I find all referable only to the white- 

 spotted species— that is, taking it for granted, as I do, that C. wolfi is not distinct from that bird. One, shot 

 in autumn near Halle, is in rather peculiar plumage, having the throat white, bordered on each side with 

 black, and washed with blue ; the black band on the breast is very indistinct ; and below it are a few dull 

 orange-red feathers. I am indebted to Mr. Bond for the loan of two specimens of the form which has been 

 described as C. wolfi, and find that, though apparently the throat is uniform blue, on moving the feathers 

 wbite appears, as some are white at the base, 



Switzerland. A single specimen in my collection, a female, is referable to the white-spotted form, and 

 closely resembles the female from Spain, which I have figured, and which has no blue on the breast. 



France. One specimen, an adult male from Rouen, in Mr. E. R. Alston's collection, has a very small 

 white spot in the centre of the blue on the throat. 



Spain. In a large series of specimens in the collection of Mr. Howard Saunders and in my own possession 

 I find a considerable variation in plumage. Many of them are in immature plumage, and are then scarcely 

 distinguishable from the young of C. suecica ; and one adult male has the throat all blue unspotted. 



Italy. A single specimen sent to me by Count Ercole Turati is an adult male of the white-spotted species, 

 having the spot very clearly defined. 



Egypt. In the collection of Captain G. E. Shelley there is a very fine series of specimens, all obtained in 

 the spring of the year. Amongst these are adult males of both the Red-spotted and the White-spotted Blue- 

 throats, thus showing that both pass there during migration. One specimen, a male, has the white spot very 

 large ; and in the centre of this white patch some of the feathers are tipped with reddish orange ; and I can 

 only suppose that it may be a cross between the two species, as it is well known that perfectly distinct though 

 closely allied species will occasionally interbreed where they meet. 



Djeddah. A single specimen collected in this locality on the shores of the Red Sea, and sent to me by 

 the late Mr. S. Stafford Allen, is a very fine male of C. suecica, having the bay breast-spot very clearly defined 

 and rich in colour. 



India. Specimens I have examined from there are all referable to C. suecica. Lord Walden informs me 

 that he has lately obtained an adult male from the Andaman Islands, which, though shot in the winter, has 

 the blue and bay on the throat very fully developed. One specimen in my collection, in immature plumage, 

 has the throat very faintly marked with yellowish, and can easily be mistaken for an immature C. wolfi. It 

 is possible, I think, that birds in this stage of plumage may have been mistaken for the White-spotted 

 Bluethroat.
