Under the name Collocalia fuciphaga Doctor Hartert reports " 

 several specimens of edible swiftlets from Bunguran Island. Though 

 we have not examined these, they are probably referable to the form 

 here listed. 



The generic name here used was originally proposed by the present 

 writer ^* as a subgenus to include the species of the genus Collocalia 

 with feathers on the tarsi, and it now seems desirable to separate 

 these species generically.
