" Found about tbe streams and small lakes in the interior of the 

 forest. The remarks of Messrs. Sclater and Salvin on this species 

 (P. Z. S. 1867, p. 981) I can verify, as I always found the two 

 supposed species together, T. hyperijthrus being; the female (bu 

 dissection)."— E. B. y

 egg is a pale whitish brown, mottled with rich reddish brown and 

 grey at the large end ; markings rather distinct. The complement 

 is four."— E. B. l
