33(3 BATKACHOSTOMUS MONILIGER. 



" Thinking at first the bird could not possibly have escaped I searched about for it, and at the foot of 

 the small tree where the nest was I found the remains of an egg. These I have kept and will send with the 

 nest, as I at least have no doubt that they originally enclosed the young Frog-mouth. You will see, from 

 these fragments, that the egg of the bird is probably pure white, almost round, of thin texture, and with a 

 smooth, glossless surface."
