lengthened ; the fourth quill

* it is singular that M. Temminck should take no notice, in his de- 
scription, of the double tooth of this remarkable bird, although it is so dis- 
tinctly expressed in his figure, Pl. Col. 10. ; neither does he say any thing 
as to the length of the wings: the tail he “describes as even, while Lesson 
asserts it to be “* un peu échancrée !”’
