Obs, Sp. Bucconi tamatice affinissima, sed gula pallidiore et 

 maculis ventris majoribus et intensioribus differt. 



This appears to be a western representative of the B. tamatia of 

 Cayenne, from which, however, I think it may be fairly separated. 

 MM. Verreaux of Paris have lately received a considerable number 

 of specimens of it from the Upper Amazon. They all present the 

 same distinctive characters as are above noticed. 



4. MONASA PERUANA.

M. plumbescenti-nigra, capite et gutture intensioribus ; fronte et 

 menti summa 'parte albis : rostro ruberrimo.

Hab. In Peruvia Orientali in regionibus fl. Amazonum superioris :

Obs. Simillima M. personatcc sed rostro clarius rubro, mento ad 

 ipsam apicem solum albo hand nisi dubie disjungenda. 



My specimen of this bird was obtained from the MM. Verreaux, 

 and carries the MS. name above quoted, which I have thought it as 

 well to adopt. The characters which separate it from its well-known 

 Brazilian representative are certainly very slight, but appear to be 

 constant in at least a dozen examples I have examined from the 

 same locality. 



5. BUCCO PICATUS. 



j^ ^j jB. supra niger ; plaga in summis scapularibus utrinque magna et 

 maculis in pileo rotundis cum loris albis: subtus albus; vitta

 extimis in medio et harum omnium apicibus albo maculatis : 

 rostro pedibusque nigris.

Obs. Species Bucconi tecto forsan nimium affinis, et ob crassitiem 

 majorem, torquem pectoris latiorem et caudam minus albo maculatam 

 non sine dubio constituenda. 



Mr. Gould's collection contains two examples of this bird, which 

 he has entrusted to me for comparison with its Cayenne representa- 

 tive. It is not, however, without hesitation that I have determined 

 to separate them from it. Besides their larger size and broader 

 breast-band, the white medial square spot extends in the present 

 species only through the three lateral rectrices, with a slight trace of 

 it in the fourth. 



In the Cayenne bird the outer five pairs are all strongly marked
