Ltpaugus murufu, is nearly o f tile same form as L . cmemceas o f Cayenne and the Amazon-
valley, lavmg the two onter toes partially united at their bases, but has the wings rather
diiferently proportioned, the third primary being longest instead o f the fifth, and the primaries
generally less pointed. It is also rather larger than L . dm r c^ u s , and totally different ill
eidoiu- It IS very smgular that all the three Central American represeiilatives o f this o-roup
ot birds, belonging to three separate and easily distinguishable sections, should be o f a general
eiiinamon-browii colour, while all the South American members o f the genus are more or less
Cinereous.
