with spiders' webs and light brown fine flbrons materials. It is securely 

 fastened to two forks of a twig-, and rests between them. The shape is 

 verj' irregular, owing to the manner in wbich it is secured to the twigs, 

 but on top the transverse diameter is about 1.50 inches, the cavity being 

 about 1 iuchacross and about .GO of an inch deep. The two eggs measure 

 respectively .32 x .50 and .34 x .49, being essentially identical in size and 

 shape with those of Calf/pte cosfre, from which it is apparently quite im- 

 possible to distinguish tbem. The other nest (No. 18564, Arroyo, north 

 of Santiago Peak, May 9) is quite different both in shape and material. 

 It is very regularly but shallowly cup-shaped, averaging a little over 

 1.50 inches in external diameter, but only about .80 of an inch in extreme 

 height. The cavity is about 1 inch across by a little over .50 of an inch 

 in depth. The material is chieliy raw cottou, but this much mixed, es- 

 pecially outwardly, with flue leaf-stems, seed-capsules, spiders' webs, 

 etc., besides one or two small soft white feathers. Like the other nest, 

 this one is supjiorted between two twigs. The eggs measure respect- 

 ively .34 X .49 and .32 x .50.— R. E.]
