besides a collection made by Mr. Andre at several localities 
on the latter river. Unfortunately the danj^ers and diffi- 
culties met with by all the explorers interfered with the 
continuance of their work, which, however, it is hoped, may 
be resumed at a later period. The un worked Sierra Parima 
could not be reached. 
From the places actually visited, how^ever, a large series 
of birds, embracing examples of no less than 468 species, was 
obtained, so that it cannot be said that the results were in 
any sense meagre. At the highest stations on the Orinoco 
many forms hitherto known only from Upper Amazonia 
were met with, whilst on the Caura the Avifauna was found 
to bear more resemblance to that of British Guiana, with 
a certain number of endemic species. 
The following are the names of the species and subspecies 
described as new : — Microcerculus caurensis, Thryothorus 
griseipectus caurensis, Troglodytes musculus clarus, Hylophilus 
thoracicus grlseiventris, Cganerpes ccerulea cherrieij Calliste 
mexicana media, Pyrocephalus rubineus saturatus, T(sniotriccus 
andrei^Habrura pectoralis brevipennis, Serpophaga orenocensis, 
Thripophaga cherrieij Automolus sclateri paraeasis, Dendrornis 
rostripallens sororia, Xiphocolaptes orenocensis, Dendrocincla 
pJidBOchroa, Thamnophilus doliatus frater cuius, Myrmotherula 
cherriei, M. cinereiventris pallida, Myrmeciza swainso?ii 
griseipectus, Saucerottea erythronotos caurensis, Chlorostilbon 
caribaeus nanus, Thalurania furcata fissilis, Lopliornis ver- 
reauxi klagesi, Chcetura andrei, Veniliornis orenocensis, 
Picumnus stellce, Capito auratus intermedius, and Ramphastos 
hcematorhynchus. Two new generic names are proposed, 
namely, Tceniotriccus (p. 38) for T. andrei from the Caura 
Kiver (a new form of Platyrhynchinse), and Phceomyias 
(p. 41) for P. incompta (Cab. et Heine), in place of Myio- 
patis, which is shown to be a synonym of Ornithion. 
The coloured plate contains excellent figures of Xenopsaris 
albinucha, Thripophaga cherriei, and Saltaior oi^enocensis. 
The occurrence so far north of Xenop saris (hitherto known 
only from Argentina) is quite a surprise to us.
