746 CORVTIS LEUCOrilyElS. 



the upper white. The feet are black, some of the scutella 

 with whitish margins, and the claws are white. The head is 

 white, but with several black feathers irregularly interspersed. 

 The reversed bristly feathers at the base of the bill are also 

 white. The hind part of the neck, the whole of the back, the 

 scapulars, and some of the wing-coverts, as well as the tail- 

 coverts, are greyish-black, glossed with blue. The tail-feathers 

 are dull black, except the basal half of the middle four, which 

 is brownish-white, and the shafts of all, which are white at the 

 base, and light brown toward the end. The primary quills, 

 their coverts, the alula, many of the smaller coverts, most of 

 the secondary coverts, and the outer secondary quills, white. In 

 the left wing, only two secondaries, but in the right seven, are 

 black ; the outer primary of the right wing is nearly all brown, 

 and two of the other primaries are tinged with that colour. 

 The throat and sides of the neck are white ; at the lov/er part 

 of the neck and fore part of the breast, is a patch of glossy 

 black, including a great part of the elongated lanceolate feathers. 

 The breast and abdomen are white, with some black feathers 

 on the sides. The smaller lower wing-coverts black, the larger 

 white ; the tibial feathers black, as are those under the tail, 

 excepting some in the middle part. The downy part of all the 

 black feathers is light grey. 



Length to end of tail about 25 inches ; bill along the ridge 

 3i\ ; its height at the base If*^ ; edge of lower mandible 3 ; 

 tarsus 2f ; hind toe 1, its claw 1^^, ; third toe 2, its claw l^^. 



M. Temminck's description agrees with this, the differences 

 being slight. The individual described by Brisson corresponds 

 in all respects with the above, only more of the tail-feathers 

 are white, and there are some differences in the quills. This 

 figure so nearly represents my specimen, that it might w^ell 

 pass as having been taken from it. As all the specimens 

 liitherto described are similar, with slight differences, it seems 

 not improbable that the Ferroe Raven is a distinct species. 

 The question, however, can be decided only by a good observer, 

 who, visiting its native country, shall investigate its habits, and 

 describe it from numerous specimens.
