D . & C [Received July 9, 1886.] To the meeting of this Society on December 1, 1885*, I communicated a paper on the " Comparative Osteology of the Trochilidae, Caprimulgidae, and Cypselidae," wherein I ventured to bring forward certain anatomical facts in support of Professor Huxley's expressed opinions upon the probable relations of the Humming-birds, Swallows, Swifts, and Nightjars (P. Z. S. 1867, p. 415). Although it does not in any way alter the general comparisons I made in m y first contribution to this subject, nor m y conclusions, yet I find an unfortunate error has crept into the drawings of one of the Plates in the paper in question (plate lxi. fig. 3). H ow this happened it would be impossible for m e to say at the present time, but the humerus of Trochilus alexandri in this figure is the right one, and not the left as stated in the text. It is quite possible that the extraordinary position of the pneumatic foramen in this bone, taken in connection with its diminutive size, or confusing the pair after the skeleton had been disarticulated for the purpose of studying the details, may have had something to do with the mistake. 1 See P.
