lines on the feathers of the light rump band, and by more glossy upper 

 surface. From Collocalia francica townsendi it differs in shorter wing, 

 less whitish rump band with conspicuous blackish shaft lines, and 

 darker abdomen. 



The subspecific separation of the present form is made principally 

 on the basis of the bird from Ternate Island, described by Count 

 Salvador! as Collocalia injuscata^^ which is certainly different from 

 both francica and spodiopygia, although considered by Dr. Hartert as 

 inseparable from the latter.^^ Although no specimens from northern 

 Queensland, the Cypselus terraereginae of Ramsay j^^have been examined 

 in the present connection, the characters of size and coloration assigned 

 them agree apparently best with this form, for which therefore terrae- 

 reginae by priority becomes the proper subspecific name. Should, 

 however, the birds from Queensland, w^hich are undoubtedly not to be 

 referred to spodiopygia, and probably not to francica, ultimately prove 

 to be different from those of the Molucca Islands, the latter must stand 

 as Collocalia francica infuscata Salvador!.

Chars, subsp. — Like Collocalia francica francica, but wing longer; 

 upper parts more blackish and less glossy; also lower surface, partic-

This dark form from western Polynesia certainly deserves recogni- 

 tion on good average characters as distinguished from Collocalia fran- 

 cica francica with which it has heretofore been synonymized. It is, 

 indeed, both in color and size, apparently nearer Collocalia francica 

 inexpectata, from which it differs chiefly in its smaller size, less 

 glossy upper surface, lighter rump band, and obsolescence, usually 

 absence, of dark shaft lines on rump and under parts. Peale's type of
