ORDER V. GRALLiE. 
These are generally long-legged wading birds, for the most part 
living in the vicinity of water, if we except the ostrich and casso- 
wary, which indeed did not originally belong to this order, as esta- 
blished by Linnaeus. Cuvier divides the entire order into five 
families, which we shall indicate by braces, and three distinct ge- 
nera, which cannot well be reduced to any of the five families, and 
which he seems to think may almost be looked on as constituting 
little families in themselves. The families he has named are, 1. 
Brevipennes , containing genera i. and ii. ; 2. Pressirostres, contain- 
ing genera iii — viii. ; 3. Cultrirostres, containing genera ix — xviii. ; 
4. Longirostres, containing genera xix. and xx. ; and, 5. Macro- 
dactyli, containing genera xxi — xxiv. ; after which come the three 
detached and concluding genera.
