been classed as a part of the genus Conurus) in a separate family, 
on account of the absence of the ambiens muscle of the knee, 
but as we are quite ignorant of the classificational value of this 
character, it is better for the present to keep both as distinct 
genera of the same family. The genera are : — 
Ara (15 sp.), Paraguay to Mexico and Cuba; Rhyncopsitta (1 
sp.), Mexico ; Henicognathus ^1 sp.), Chili ; Conurus (30 sp.), the 
range of the family; Pyrrhura (16 sp.), Paraguay and Bolivia to 
Costa Rica; Bolborhynchus (7 sp.), La Plata, Bolivia and West 
Peru, with one species in Mexico and Guatemala ; Brotogerys (9 
sp.), Brazil to Mexico.

The Psittacidae comprise a somewhat heterogeneous assemblage 
of Parrots and Paroquets of the Neotropical and Ethiopian regions, 
which are combined here more for convenience than because 
they are believed' to form a natural group. The genera Chrysotis 
and Pionus have no oil-gland, while Psittacula and Agapornis 
have lost the furcula, but neither of these characters are pro- 
bably of more than generic value. The genera are : — 
Psittacus (2 sp.), West Africa; Coracopsis (5 sp.), Madagascar, 
Comoro, and Seychelle Islands ; Pyocephalus (9 sp.), all Tropical 
and South Africa ; ( 2063 “ 206G ) Caica (9 sp.), Mexico to Amazonia ; 
Chrysotis (32 sp.), Paraguay to Mexico and the West Indian 
Islands ; Triclaria (1 sp.), Brazil : Beroptyus (1 sp.), Amazonia ; 
Pionus (9 sp.), Paraguay to Mexico ; Urochroma (7 sp.), Tro- 
pical South America; Psittacula (6 sp.), Brazil to Mexico; 
Poliopsilta (2 sp.), Madagascar and West Africa; Agapornis (4 
sp.), Tropical and South Africa.
