The geographic ranges of _H. chloris_ and _H. cinnamomina_ in Micronesia overlap only at Palau as shown by Mayr (1942b:181). Even here each is restricted to a different habitat. Possibly the present ranges resulted from competition between each group, and both may have had more extensive ranges in Micronesia in the past. Another possibility is that the original stock of _H. chloris_ arrived in Micronesia via the Palaus and that of _H. cinnamomina_ via Ponapé (eastern Carolinas), and that the resulting successful colonizations were a matter of chance. If this were the case the present day ranges may represent the total amount of dispersal that has taken place. The absence of kingfishers from Kusaie, Yap, Truk and other apparently suitable islands favors this possibility. =Eurystomus orientalis connectens= Stresemann Dollar Bird _Eurystomus orientalis connectens_ Stresemann, Novit. Zool., 20, 1913, p. 302. (Type locality, Moa.) _Eurystomus orientalis connectens_ Yamashina, Tori, 10, 1940, p. 675 (Babelthuap); Hand-list Japanese Birds, 3d ed., 1942, p. 199 (Babelthuap). _Eurystomus orientalis pacificus_ Mayr, Birds Southwest Pacific, 1945, p. 302 (Palau). _Geographic range._--Celebes and adjacent islands, Lesser Sunda Islands from Lombock to Damar, Southeastern Islands. In Micronesia: Palau Islands--Babelthuap. _Remarks._--Yamashina (1940:675) records an adult male taken at Babelthuap in 1938. He assigns it to _E. o. connectens_, comparing it with a series of 15 specimens of this race from Celebes, Halmahera and Batchian. Mayr (1045a:302) refers this visitor to Palau to _E. o. pacificus_ (Latham); this form is migratory and may fly north from Australia to the Melanesian area between breeding seasons. =Hirundo rustica gutturalis= Scopoli Eastern Barn Swallow _Hirundo gutturalis_ Scopoli, Del.
