GREY CRAXE. 21 



rounded above. The bill is nearly twice as long as the head, 

 rather stout, straight, much compressed, tapering to a rather 

 obtuse point ; the upper mandible with the ridge rather broad 

 and flat, the nasal sinus large, of great length, and filled by 

 a bare membrane ; the lower mandible with the angle ex- 

 tending as far as the middle and very narrow, the ridge 

 convex ; the edges of both sharp but strong, and the tips 

 narrowed but rather thin-edged and somewhat obtuse. The 

 gape-line, which is straight, commences far before the eyes ; 

 and the mouth is narrow, measuring scarcely an inch across. 



The nostrils are linear, ten-twelfths of an inch long, near 

 the middle of the bill, in the fore part of the nasal membrane. 

 The eyes are of moderate size, or rather small, their aperture 

 being eight-twelfths. The opening of the ear is very small, 

 being only a quarter of an inch in diameter. The feet are 

 very long, and slender, but strong. The tibia, which is 

 covered with hexagonal scales, is bare for three inches and a 

 half ; the tarsus is covered behind and on the sides with 

 scales, but anteriorly with forty broad decurved scutella. 

 The first or hind toe is very small, a little elevated, with 

 twelve scutella ; the second with twenty-two, the third 

 thirty-eight, the fourth twenty-eight ; the second toe a little 

 shorter than the fourth, but with its claw longer. The claws 

 are small, conical, decurved, little compressed, acute ; the first 

 smallest, the third largest, and with a dilated inner edge. 



The forehead and loral spaces are thinly covered with 

 blackish hairs ; the upper part of the head also bare, papil- 

 late behind, and with some blackish hairs. On the nape the 

 feathers are pointed, on the cheeks and throat linear, on the 

 neck oblong, gradually enlarging downwards ; on the body 

 broad, narrower on the hind part of the back. The Avings 

 are very long and of great breadth ; the third quill longest, 

 the second and fourth scarcely shorter, the first an inch 

 shorter; the outer primaries decurved, narrowed, and pointed ; 

 the secondaries very broad, some of the inner curved out- 

 wards, loose at the margin, and exceeding the primaries, 

 when the wing is closed, by about four inches ; some of the 

 inner secondary coverts are also curved and decomposed. 

 The tail is short, and rounded.
