the fo]loM"ing note : — " Cayenne Wood-Rails were seen every dav, 

 but were not aljimdant. A p dr were nesting near the island, 

 and well merited their native name of Kiliioow, screamins a 

 confused chorus of syllables resembling these for five minutes at 

 a stretch every morning."' 



Sehominirgk states (Reis. Gu'an. iii. p. 750) tliat he found 

 this bird most common in the coast-woods, the bo^rofv Avicennien- 

 bush, and the coffee plantations. He met with them in small 

 flocks, wldcli on his approach took to their wings. Tliey appesired 

 to depend on their wings to evade him rather than their feet. 

 Even when running a very short distance their progress was aided 

 by their outspread wings. The "' Warraus '* call it Aku and the 

 " Macusis ■' Kosarre.
