coverts, the under wing coverts, and inner margins of quills white ; the 

 under plumage pure white, except on the lower part of the abdomen 

 where it is blackish grey, and the side feathers covering the thighs which 

 are black ; the feathers of the thighs are black at the base, and largely- 

 white at the ends so as almost to conceal the black portion ; crissum jet 

 black ; bill and legs black.

Female. The plumage above is of a deep bright rufous, the inter- 

 scapular spot equally as large and white as in the male ; tail dark 

 brownish cinnamon ; inner webs of quills dark livery brown, the outer 

 webs and the wing coverts colored like the back; under lining of wings 

 white, inner margins of quills greyish white ; the under plumage is 

 white, with the sides and abdomen light cinereous, the lower part of the 

 abdomen and side feathers covering the thighs light rufous ; the thighs 

 and under tail coverts deeper rufous ; bill and feet black ; in size not 

 differing materially from the male. 



Remarks. — It has for its allies T. melanurus, transandeanus, 

 and melanocrissus, but is larger and lias a more powerful bill 

 than either ; in its black crissum it resembles the last two, but 

 transandeanus in this part has the feathers ending with white, 

 and has the entire abdomen pure white, with the long side fea- 

 thers lying over the thighs light cinereous ; the female of tran- 

 sandeanus is of a lighter color. I have but one male specimen 

 of melanocrissus with which to compare, this is less white 

 underneath than any of its affines, the sides of the breast and of 

 the abdomen being largely washed with blackish cinereous ; the 

 wing coverts, in my specimen, are without white ends except 

 two of the larger, which are just tipped with that color; it also 

 differs from the present bird, and all the others, in having the 

 black on the sides of the head, as far down as, and on a line 

 with the lower part of the under mandible ; in all the others 

 the black terminates on a line with the rictus. 

 . I do not make a comparison with T. melanurus, as in that 

 species the crissum is white. 



This fine species I have dedicated to Mr. H. E. Holland, as a
