_Description._--Above greenish grey, finely crossed by narrow
fulvous vermiculations; head and neck uniform rusty red: beneath
greyish fulvous; breast flammulated with white; flanks and under
wing-coverts black with white cross bars: whole length 18·0 inches,

_Hab._ Paraguay and N. Argentina.
Graf v. Berlepsch has recently shown that the Tiger-Bittern of Paraguay
differs from _Tigrisoma brasiliense_ (which it generally resembles in
plumage) in having the base of the lower mandible partly feathered as in
_T. fasciatum_. It is probable that the Argentine Tiger-Bittern belongs
to the same form, but we have not yet met with adult specimens of it. It
occurs in the northern provinces of the Republic, and was obtained by
White in Corrientes, and by Durnford in Salta.
