The female of Sauropatis chloris collaris differs but slightly from 

 the male, though it has usually somewhat duller, more olivaceous 

 upper parts, a well-marked blackish nuchal band, and more blackish 

 (less greenish) auricularg. 



A large series of specimens from various parts of the range of this 

 subspecies indicates that there is little if any geographic variation 

 within these limits, since birds from the islands of Mindoro, Luzon, 

 and Mindanao are, so far as we can. see, identical in color. That any 

 difference in dimensions is wholly negligible the following com- 

 parison of average measurements demonstrates:

Ten males, Irom Luzon Island 



Ten males, from Mindanao Island.. 

 Eight males, from Mindoro Island.. 

 Ten females, from Luzon Island . . . 

 Six females, from Mindanao Island.

The colors of the soft parts, as given on the labels of specimens 

 examined, are as follows: Iris grayish brown; bill plumbeous black, 

 broadly flesh color at base of mandible ; feet purplish gray, the soles 

 yellowish. 



Some idea of the breeding season may be obtained from the note 

 on one of the labels that a well-formed Qgg was found in the oviduct 

 of a bird collected on March 23. One bird in molt was taken on 

 January 18, 



The proper subspecific name for the present race is undoubtedly 

 Sauropatis chloris collaris^ as above indicated, since both Alcedo 

 chloris Boddaert^ and Alcedo chlorocephala Gmelin^ ^Pply cer- 

 tainly to the form from the Molucca Islands. 



One hundred and seventy-two specimens of this race have been 

 examined, from the following localities in the Philippine Archi- 

 pelago :
