de Beltran in Southern Jalisco in March. It is everywhere abundant on the Isthmus 
of Tehuantepec, living in woods, on plains, and in the neighbourhood of inhabited 
places. Passing southwards into Guatemala it occurs in the coast-lands bordering the 
Pacific at Retalhuleu; but the only place we ever saw it on the eastern side of the 
cordillera was the neighbourhood of some hot springs on the roadside between the 
Rio Motagua and Chuacus in Vera Paz. Here we never failed when passing to see a 
small flock of these birds in the trees about the springs, where they kept company 
with a flock of Chrysotis albifrons. In Salvador, C. canicularis has been found at 
La Libertad on the coast, and still keeping to the Pacific side of the mountains in 
Honduras, where Taylor says it is abundant®. There is a specimen in the British 
Museum said to have come from Nicaragua, but we have no skins from the collectors 
who have recently worked in that country. It is recorded from Costa Rica, and this 
is the extremity of its range in that direction 1! 14, 
PYRRHURA. 
Pyrrhura, Bonaparte, Naumannia, 1856, p. 383; Salvadori, Cat. Birds Brit. Mus. xx. p. 211. 
Pyrrhura is a purely Neotropical genus, containing nineteen species, only one of 
which is found within our limits, the rest being distributed over nearly the whole of 
South America as far south as the northern provinces of Argentina. The single 
Central-American species, P. hoffmanni, is only found in Costa Rica and the adjoining 
part of the State of Panama. 
As a genus, Pyrrhura has a general resemblance to Conurus, so far as its shape is 
concerned, but differs much in coloration and in several points of structure. The 
naked cere has no small isolated feathers surrounding the nostril as in many Conuri; 
the fourth primary is not attenuated at the end; the tail beneath is red or brownish 
red. and in many species on the upperside also. The ambiens muscle, according to 
Garrod, is absent, being present in Conurus, and on this fact he laid much stress when 
constructing his classification of Parrots.
