on sides of head, the feathers of lores with pure white bases, those of 

 middle of lower throat and breast slightly, of the sides and flanks more 

 or less broadly, margined with whitish; centre of abdomen white; lower 

 tail-coverts dusky with a slight greenish gloss, the longest ones nar- 

 rowly, the shorter ones conspicuously edged all around with white, 

 some of the shortest entirely white save for a narrow dusky shaft line ; 

 under wing-coverts blackish with the dull oil-green gloss of the upper 

 surface; a few of the dark brown axillars tipped with white. 



This remarkably distinct species continues to be known from only 

 the type specimen, which was obtained by Messrs. Goss and Dodge 

 during their recent expedition to Mount Kina Balu. This example 

 is fully adult and in perfect plumage. 



By reason of its white abdomen, uniform greenish upper parts, with 

 lack of any white on the rump and also of white markings on the tail, 

 Collocalia dodgei needs special comparison with none of its congeners 

 unless it be C. linchi. From the typical form of the latter species it 

 differs even more than from C. I. isonota, the one to which it seems to 

 be most closely allied, but from which, however, it is specifically dis- 

 tinct. Whether the previous records of Collocalia linchi from ]\Iount 

 Kina Balu and from other parts of Borneo belong to this newly de- 

 scribed species or to some form of linchi we are unable with our pre- 

 sent material to determine, and this will be an interesting question for 

 future investigation.

Chars, sp. — Resembling Collocalia linchi, but averaging decidedly 

 smaller ; most of the rectrices with large white spots on the basal por- 

 tion of their inner webs. 



Wing, 69-103; tail, 38-44; exposed culmen, 3.5-4; tarsus, 8 mm. 



Type locality. — Amboina Island, Molucca Islands. 



Geographical distribution. — East India Islands from Celebes and 

 Sumbawa Island to the Solomon Islands and the Louisiade Archi- 

 pelago, including New Guinea; Cape York, Queensland, Australia. 



Dr. Hartert is undoubtedly correct in his identification and adoption 

 of Linnseus' Hirundo esculenta, ^^ even though the latter author gives
