26. AsTURiNA NiTiDA NiTiDA (Latham). 



Three specimens, one adult and two immature, Vicinity of Para- 

 maribo, January, April, and August. 



27. RUPORNIS MAGNIROSTRIS MAGNIROSTRIS (GmcUn). 



Seven specimens, both sexes, Vicinity of Paramaribo, and Wana- 

 weg, March, April, May, and June. 



One skin, (464 Penard Coll.), is so much like R. ni. occidua Bangs 

 as to be practically indistinguishable. It is noteworthy that this par- 

 ticular bird is the only one collected away from the city, and was taken 

 at Wanaweg. It may be a straggler of R. m. occidua, but we do not 

 care to record it as such, since the similarity in coloration may be 

 due to individual variation. 



On examining a large series of the various forms of Rupornis magni- 

 rostris, the eastern Colombian bird stands out clearly, and may be 

 known as 



27a. Rupornis magnirostris insidiatrix, subsp. nov. 



Type.— M. -C. Z. E. A. & O. Bangs Coll. 5,014. Adult 9 Santa 

 Marta Mountains, Colombia. 16 January, 1898. W. W. Brown, Jr. 



Characters. — In general like R. m. magnirostris (Gmel.), and of 

 about the same size, but paler; upper parts and chest decidedly 

 paler gray; the darker barring on breast and sides paler and less 

 dusky, producing less contrast with the white bars. 



28. Busarellus nigricollis (Latham). 



Six specimens, both sexes, adult and immature, Vicinity of Para- 

 maribo, January, March, April, and June. 



These specimens average slightly smaller than Central American 

 birds examined, but we cannot detect any differences in color. 



29. BuTEOGALLUS AEQUiNOCTiALis (Gmclin). 

 » 

 One adult cf and one immature, Fort Nieuw Amsterdam, and 

 Tijgerbank, April, and September.
