S ad. Nearest to, and agreeing with, T. rristatm bruitneiis (Spix), of Eastern 

 Brazil (from Para to S. Panlo), in having the crest deep tier}' or vermilion-red and 

 bordered in front only by a rather narrow, bright bnff line, but crest-feathers mnch 

 shorter — scarcely longer than in T. c. cri.status, from Cayenne, etc. — and whole 

 throat, except a small blackish chin-spot, deep ochraceous buff. 



? ad. Not different from that of T. r. cristatus. 



Type in Tring Museum : S ad., Calama, 2. viii. 1007 (W. Hoffmanns coll., 

 No. 320). 



Besides the above serie.«, I have before me the adult male from Humaytha 

 obtained on Mr, Hoffmanns' first trip to the Rio Madeira, and several examples, 

 among them an adult female, belonging to the Vienna Museum (Natterer coll.). 

 Compared with some thirty skins from Para, Pernambuco, Bahia, and Rio de 

 Janeiro, the Madeira birds have the crest invariably shorter and generally of a 

 deeper fiery red. Even more strongly marked is the difference in the extent of the 

 ochraceous gular spot. The Calama and Humaytha specimens have the whole 

 throat, with the exception of a very small black chin-spot, deep ochraceous buff, 

 while in T. c. brunneus there is but a broad stripe of a clearer bnff along the middle 

 of the throat, the sides of the latter, as well as a large patch on the chin, being 

 dull black like the remainder of the lower j)arts. T. c. cristatus (and the doubt- 

 fully distinct T. c. cristatellus) may be distinguished from the new form by their 

 smaller gular spot, and particularly by the much lighter, orange-red crest, bordered 

 in front and laterally by a broad, creamy bnff margin. 



7'. c. madeirae appears to be restricted to the Madeira Valley and its head- 

 waters, Gnapore, etc. ; for specimens from the Rio Negro (Barcellos, Marabitanas) 

 and Northern Pern (Loretoyacu, Peru) agree in every respect with Bogota skins 

 (so-called cristatellus).*

 brown, feet pale greyish yellow, bill black." — Wing 85, 82; tail 82; bill 15J,

* The supposed femiile of Tachi/jilwniis uatlereri I'elz. (I.e. p. 32S : ^ ad. Villa Maria. Riu Paraguay) 

 was secured at Saltu du Girao by Natterer. It is, however, doubtful whether it really belongs tii 

 T. natlercri, and the question must be left in abeyance until adult males from that locality come to 

 hand.
