Remarks. — Thanks to Mr. C. M. Weber, I have been able to 

 obtain a remarkable series of two hundred twenty-two specimens 

 of this little-known Philippine species. Of these eighty-six were 

 females, and one hundred thirty-six males. All are from Sibu- 

 yan. No specimen has yet been taken elsewhere in the Visayas, 

 but it very probably occurs in Romblon and Tablas, since it is 

 found in Mindoro. The males and females are very different in 

 appearance. The following characters are constant throughout 

 the series. The male has a brilliant, immaculate, yellow gular 

 appendage, a strong nuchal fold with small serrated crest; the 

 wings are yellow and the orbit black or dark brown ; the female 

 has a larger body and a larger head with distinct nuchal and 

 inter orbital spots. The orbit is never of a solid color. The light 

 spot on the throat, the blackish wings with grayish spots forming 

 curved longitudinal lines, and a lemon yellow wash on wing 

 membrane below are constant characters. In the young these sex 

 differences are not so evident, as the young males resemble the 

 females. 



The species is very distinct; its closest affinity appears to be 

 Draco spiloptems. The species appears to have been collected 

 for the first time in Sibuyan by Jose Quadras, for whom it was 

 named by Boettger. I collected a single specimen on the western 

 coast of Mindoro.
