D'Orbigny, from either of which it may be distinguished by its black nares and 

 ear;:, and also by the absence of purple on the breast. In the species now de- 

 scribed, of which I have seen six specimens, the throat and breast are of the 

 same colour, exactly as the upper part of the head, without the slighest appear- 

 ance of the purple into which the crimson changes in both the species men- 

 tioned. The legs, also, in the present species, are nearly or quite black, in 

 which respect they differ from those of T. capilntu, which are yellow. 



A specimen of this remarkable species was obtained in Europe by Mr. Edward 

 Wilson, to whose valuable additions to the collection of the Academy I have fre- 

 quently alluded. I have also seen other specimens, two of which I procured from 

 a collection, brought from the Rio Negro by Mr. John Willf, an intelligent mer- 

 chant, formerly resident at Para.

The right lung is greatly enlarged and tuberculous; the tuberculous matter 

 exists in the form of infiltration, and is disseminated in masses leaving inter- 

 vening spaces of hepatized lung of a brick-red colour, firm and resisting to the 

 touch ; the greater portion of the lower lobe of this lung, as well as a very con- 

 siderable part of the upper, is occupied with this matter ; the opposite 

 lung is comparatively healthy, a few tuberculous dei)osits being observed at its 

 root and apex, and also in the lower lobe, which is somewhat congested. Several 

 of the bronchial glands are enlarged, one of them measuring fourteen lines in 

 length. Pericardium pale, containing no serosity ; coronary veins much enlarged. 

 Abdomen. Mucous membrane of oesophagus pale, apparently healthy ; the liver is 

 of a dark-chocolate colour, and has four lobes; the second of these counting from 

 the right is the largest; the liver measures five and a half inches transversely, 

 three inches antero-posteriorly, and one and a quarter in depth ; no tuber- 

 cles are observed in it; the gall-bladder, which lies in a sulcus upon the under 

 surface of the largest lobe is moderately distended with bile, tinging its parietes 

 a light-green colour ; the spleen measures three and three quarter inches in length 

 by one and a half in breadth in its broadest part ; it is elongated at its right ex- 

 tremity, tapering.almost toa point ; the opposite extremity is rounded, the entire 

 organ presenting a somewhat triangular form ; no tubercles are observed in any 

 part of it ; its tissue is of a deep-purple colour, almost black from congestion ; 

 the stomach measures six inches transversely, by three and a half from the 

 entrance of the oesophagus to its greater curvature ; its muscular fibres are very 

 apparent; the oesophagus enters it about the middle of the lesser curvature ; the 

 mucous membrane of the stomach is of a brownish-red colour near the pylorus, 

 elsewhere of a pale onion tint ; no crypts are observable ; the pancreas measures 

 three inches transversely, one and a quarter in its greatest breadth near its head; 

 the large intestine, including the coecum, measures two feet nine and a half
