the larger end, a few fine hair-like scribblings crossing the shell trans- 

 versely. Measurements 17 mm. by 12 mm." 



Another set of two eggs, collected by Whitehead in Negros, April 15, 

 1896, are described as having the "Ground-color as in the above, but ihe 

 shell heavily clouded with rich dark terra-cotta and darker scribblings 

 and specks of the same color. Measurements 16 mm. by 12 mm." 



"This sunbird nests in old forest. The nest is generally found sus- 

 pended among forest debris in the vicinity of some huge tree-trunks only 

 a few feet from the ground. It is well hidden by the undergrowth. 



"The nest is a well-woven bag-shaped structure, with a roofed entrance 

 at the side. It is principally constructed of fine grass, rootlets, palm 

 fiber, and fragments of dead leaves woven together with spiders' webs 

 and lined with fine dead grass tops and seeds. The nest found by 

 Professor Steere was suspended from a root under the overhanging bank 

 of a river, and looked like a tuft of rubbish left by high water." ( Grant 

 and Whitehead.)
