PYREHULAUDA GEISEA. 
clios-cu by this curious little bird to build in, the following instance related by Mr. Hume is the most extra- 
ordinary that has come under my notice. He writes (' Nests and Eggs ’) : — “ I may note that at Etawah we 
found a nest of this species also amongst the ballast between the rails, so that here too ” (in reference pro- 
bably to the nest of another speeies) “ the trains must have passed a dozen times a day and night over the 
sitting bird. When we think of the terrible heat glowing from the bottom of the engine and the perpetual 
dusting-out of hot cinders, it seems marvellous how the bird could have maintained her position.” 
I would suggest that in this case the bird allowed the heat of the sun to incubate the eggs by day, and 
that she only sat at night, and being asleep was not disturbed by the trains. The average of thirty eggs is 
0'73 by 0'55 inch.
