184 TINAMIFORMES "CHAP. 
As will be seen from the following examples, the general 
coloration is rufous or slaty-brown, which may be relieved by 
buff, or barred with blackish above and even below; the under 
parts being often greyer, with whitish throat and belly. The sexes 
do not differ greatly, but the female is, if anything, the larger 
bird. Some six forms occur in Mexico, while of the remainder 
Tinamotis ingoufi extends the range to Southern Patagonia. 
The genus 7inamus has ten members, 7’. tao, of South America 
north of Bolivia and Brazil, being greyish-olive, with slaty breast 
and buff abdomen, wavy blackish markings on both surfaces, black 
primaries, black head and neck with white spots and bands on the 
sides, and still whiter throat. Of the thirty or more species of 
Crypturus, C. tataupa, extending from Peru and Bolivia to Brazil 
and Argentina, is plain chestnut-brown, with blackish crown, 
grey cheeks, neck, and breast, whitish throat and belly, buffish 
flanks with black crescentic bars, red beak, and pinkish feet. 
It haunts dense under- 
erowth in forests, even 
near habitations, and 
frequently sits bent for- 
ward with its “ tail” ex- 
panded over its back; 
its melody consists of 
several notes at dimin- 
ishing intervals, merg- 
ing into a hurried trill, 
which is terminated by 
a reiterated sound like 
“chororo”; its eggs are 
of a reddish chocolate- 
colour. Rhynchotus 
rufescens of the same 
countries except Peru, 
the “ Perdiz grande” 
of Argentina, which is 
represented in Bolivia 
by the similar A. maculicollis, is grey-brown, with blacker crown, 
rufous cheeks, neck, and breast, and chestnut primaries; the 
back being barred with whitish and black, and the flanks 
with brown and white. This somewhat solitary bird threads
