$ Brownish-ash, with a faint olive shade, the wings and tail purer and 

 darker fuscous, without white edging or tipping. Below, a paler shade of 

 the color of the upper parts. Throat and side of the lower jaw white, 

 with sharp black maxillary strealks. Cheeks and auriculars speckled with 

 whitish. Under tail-coverts deep rich chestnut, in marked contrast 

 with the surrounding parts. Bill black, slenderer for its lengch than

that of any other species, as long as that of redirivua, arcuate. Length, 

 about 12 inches ; wing, 4 or rather less ; tail, about 6 (more or less, 

 thus absolutely longer than in any other species), its lateral feathers 1^ 

 shorter than the central ones ; bill, 1^ ; tarsus, 1^- ; middle toe and claw, 1}. 

 Belonging to the group of unspotted Thrashers, with very long arcuate 

 bills, this fine species is immediately distinguished by the abruptly chestnut 

 under tail-coverts, the contrast being fully as great as that seen in the Cat- 

 bird, Mimus carolinensis—in fact, the bird looks not very unlike a gigantic 

 faded-out Catbird. The sharp black maxillary streaks are also a strong 

 character. The bill is extremely slender, the tail at a maximum of length, 

 and the feet are notably smaller than those of 3. redivivm.
