Amongst the numerous birds, collected by the Dutch botanist Teysmann in the district of Macassar during the year 1878, the Leyden Museum is in possession of a specimen of the genus Cinnyris, which I am not able to identify with any known species and which I introduce here under the name of Cinnyris Teysmanni. Entire crown, sides of head, hind neck, mantle, back and rump, wing-coverts and outer edge of quills uniform earthy brown with a slight tinge of olive, upper tailcoverts purplish brown, tail-feathers purplish black, the outer webs narrowly edged with metallic green; chin and throat metallic purplish blue, flanked on both sides with a broad metallic green stripe, forming a moustachial streak which is produced down to the sides of the chest; the latter is separated from the breast by a narrow maroonbrown cross-bar which is somewhat paler than in C. asiaticus: breast, flanks, abdomen and under tail-coverts black with a purplish gloss, pectoral tufts bright yellow without any trace of orange-red, under wing-coverts and thighs dusky black; bill of the same size as in C. asiaticus and C. zenobia, but rather less strongly bent, black; feet black. Wing 5,3 cm.; tail 3,5; tarsus 1,5, bill from front 1,8.
