THYRORHINA. — PORZANA. 71 



Hahits. Schombiirgk says (Reis. Guian. ii. p. 245) that he 

 obtained this bird in the vicinity of Mount Roraima. He always 

 found them in pairs. It is easily caught, as its feeble powers 

 of flight only allowed it to remain on the wing for a short time. 

 He kept a pair in captivity for some considerable time ; the male 

 died first, however, and the female only survived him for one 

 day — having died from grief.
