FLOCKY MAUCAUCO, 
and toes, and even the nails, are black. The 
great-toes of the hind-feet, are large, and have 
thin round nails; and the second toes are each 
connected to the great-toes by a blackish mem- 
brane. 
Such are the animals which some natura-. 
lists consider as varieties only of the Flocky 
Maucauco. Every nice observer, however, 
caiinot fail to perceive very sensible differences; 
but it is not, perhaps, quite so easy to decidcj 
whether they are sufficient to constitute distinct 
species, respecting which there will probably 
continue to be various opinions.
