All the specimens of this species that we have examined, both in 

 the McConnell collection and that of the British Museum, belong 

 to B. pinnatus Wagl. ; and we very much doubt if B. lentiginosus 

 Mont, has really occurred in British Guiana. 



Habits. Schomburgk states (Reis. Guian. iii. p. 754) that this 

 bird inhabits the Savanna swamps and that its habits are tlie same 

 as those of the European Bittern (B. stellaris). The "Macusis'^ 

 call it Tunahorucka and the "Warraus^' Unko. 



Mr. J. J. Quelch (Timehri (2) ii. p. 303) observed this species 

 on the Abary River, where he says that the " quaaks were heard 

 all through the day."

The chief characters of this family are the large body, small 

 head, short legs, and large feet. It includes two genera and three 

 species, all of which are restricted to South America. One genus
