for this same species, but as the type has disappeared, and no 
specific characters have been published for the name, it is difficult 
to be certain on that point. 
3. Bucco putmentum. (Pl. CVI.) 
Tamatia (Nyctactes) pulmentum, Bp. et Verr. MS. 
B. supra fusco-brunneus; fronte et superciliis rufescentibus ; 
torque angusto nuchali inconspicuo albido ; dorsi medii alarum 
uropyguque plumis partim fulvo terminatis: subtus albus ; 
gutture inferiore pallide rufescente ; plaga utrinque gutturali 
magna cum maculis crebris pectus totum et ventrem (precipue 
ad latera) occupantibus atris: rostro nigro. 
Long. tota 5°0; ale 3°1; caudz 2°5. 
Hab. in Peruvia Orientali et regionibus fl. Amazonum superioris : 
Pebas (Cast. et Dev.): Chamicurros (Hawawell). Mus. Paris., 
Joh. Gould et P.L.S. 
Obs. Sp. Buceoni tamatie affinissima, sed gula pallitione 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. MoNnASA PERUANA. 
Monasa peruana, Bp. et Verr. MS. 
M. plumbescenti-nigra, capite et gutture intensioribus ; fronte et 
menti summa parte albis: rostro ruberrimo. 
Long. tota 11°0; ale 5:0; caudze 4°5. 
Hab. In Peruvia Orientali in regionibus fl. Amazonum superioris : 
Chamicurros (Hawawell). Mus. Joh. Gould et P.L.S. 
Obs. Simillima M. personate sed rostro clarius rubro, mento ad 
ipsam apicem solum albo haud 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. 
B. supra niger ; plaga in summis scapularibus utrinque magna et 
maculis in pileo rotundis cum loris albis: subtus albus; vitta

rostro pedibusque nigris. 
Long. tota 6°7 ; alee 3°2; caude 2°3.
