The Ponapé Cicada Bird, _E. t. insperatum_, appears to represent a colonization distinct from that which established the populations at Yap and Palau. This conclusion is based on the fact that the adult female of _E. t. insperatum_ has distinctive reddish coloring and lacks the barring on the underparts, and that it may have been derived from an ancestral stock, which was reddish and not barred, such as _E. t. remotum_ of the New Ireland area. The three subspecies in Micronesia may represent remnants of a single colonization, since additional material from Yap may prove that this island population has characters intermediate between those of the other subspecies of Micronesia. =Dicrurus macrocercus harterti= S.

In Micronesia: Mariana Islands--Rota (introduced). _Specimens examined._--Total number, 7 (4 males, 3 females), from Mariana Islands, USNM--Rota (Oct. 18, 19, Nov. 2). _Remarks._--This drongo was introduced from Formosa to Rota by the Japanese South Seas Development Company (Nanyo Kohatsu Kabushiki Kaisha) apparently in 1935. An illustrated booklet, printed by this organization and seen by members of the NAMRU2 party at the Rota Civil Government headquarters, showed pictures of the captive birds before release and indicated that they had been brought to Rota for the purpose of controlling destructive insects. Dr. Charles Vaurie has examined these birds and compared them with a series of drongos from Formosa in the collection of the American Museum of Natural History. The drongo appears well adapted at Rota, where it prefers cultivated areas and the bombed village sites to thick woodlands. Birds were found in small flocks often perched in large shade trees in village areas. Weights of two immature males are 53 and 61 grams. One adult male measures: wing, 144, tail, 153, culmen, 26, tarsus, 22. =Corvus kubaryi= Reichenow Marianas Crow _Corvus Kubaryi_ Reichenow, Journ. f. Ornith., 1885, p. 110.
