THE TATAUPA. 
Fourteen or fifteen species of these curious birds 
are described, but their history is not well known, 
and there is considerable confusion among their 
names, from the works of Spix affixing new appella- 
tions to almost all that were known. One of the 
most curious is the Tinainus nanus of Temminek, 
of very diminutive size, being about a third less than 
the common quail. It is very interesting from its 
form, which approaches in many respects to that of 
Ortygis, and is thought by Temminrk to stand at 
the extremity of the present genus, and lead to that 
we have just mentioned. The hallux is simply a 
nail, and there is an extraordinary development in 
the feathers of the rump. It will stand as the type 
of a subgenus.
