(syn. Pogoniulus Ϯ Yellow-rumped Tinkerbird P. bilineatus) Gr. μικρος mikros little; genus Pogonias Illiger, 1811, barbet; "Barbatula = Pogoniulus Lafrsn. (cf. Oberholser, l.c. p. 867, and Richmond, Proc. U.S. Nat. Mus. xxv. 634, 1909). I consider, however, that the three species occurring within our limits cannot be referred to the same grouip, Megalaema bilineata Sundevall differing from the other two, more typical, species in having the top of the head to the back uniform glossy blue-black and the bill larger, although the bird itself is smaller; this species I therefore propose to remove to another subgenus under the name of MICROPOGONIUS."
