Natterer collected four examples of this beautiful species of Ma- 
nakin (which is no. 737 of his MS. Catalogue) at Borba in January 
1830—one male and four females. A skin previously obtained at 
Enganho do Gama, in August 1826, may probably be referable to the 
female of the same species, but differs slightly in having the crown 
less bluish. 
Pipra nattereri, as I propose to call this bird, with Herr von 
Pelzelu’s approbation (since its indefatigable discoverer left it un- 
named), may be placed near Pipra isidori and P. serena. It is 
easily known, however, by its green body-colour and pure-white cap 
and rump. Herr von Pelzeln has kindly allowed me to acquire one 
of the females from Natterer’s series, while a coloured sketch of the 
male kindly forwarded to me by the same obliging friend enables me 
to have the other sex represented in the accompanying plate. 
The following extracts are from Natterer’s MS. Journal, and 
relate to this species: — 
““Weibchen, Enganho do Cap Gama, 10 August 1826, im hohen 
Wald, auf niederen Baumen. Iris schmutzigweiss, Oberschnabel 
schwarzgrau, der Rand desselben (die Schneide) samt dem Unter- 
schnabel hellgrau, Fiisse hellgelblichbraun, Klauen etwas dunkler. 
Dieses Weibchen unterscheidet sich von jenem von Borba durch den 
Mangel des blaulichen Scheitels und konnte vielleicht zu einer an- 
deren Art gehéren. 
**Mannchen (nicht in der Mause), Borba, Jiinner 1830, aus dem 
Urwald. Iris schmutzigweiss. Der Riicken des Oberschnabels 
graulich schwarz, der Rand desselben und der Unterschnabel hell- 
blaulichgrau. Die Fiisse sind hellgelblichbraun, Klauen grau. Der 
ganze Scheitel und Unterriicken blendend Weiss mit Seidenglanz, 
rothlich opalisirend. 
‘‘ Weibchen alt, Borba, 9 Februar 1830, aus dem Urwald, einzeln. 
Iris schmutzigweiss. Oberschnabel graulichschwarz, der Rand des- 
selben und der Unterschnabel blaugrau. Fiisse hellgelblichgrau. 
Die Klauen viel bliisser, fast hautfarben.”’

Dr. Peters, in his ‘ Reise nach Mossambique,’ has given a careful 
description, accompanied by excellent illustrations, of three small 
species of this family. Dr. Gray, in an interesting paper (revising
