Show 522 MR. G. A. BOULENGER ON N E W [June 6, horizon of the present specimen may be taken as an almost certain indication of its distinctness from that form, I propose to regard it as representing a new species, under the name of T. majori. In the absence of a specimen of the humerus of T. lartetianus available for comparison, I am, however, unable to point out the distinctive differences of the present bone. UNDETERMINED SPECIMENS. Among the undetermined specimens there are several complete bones undoubtedly referable to small Passerines, although the materials available to m e do not admit of any satisfactory attempts at their generic discrimination. In figure 15 of Plate X L L I have, however, figured a left humerus which may be Picarian, in the hope that some one better acquainted with the osteology of these groups of birds may be able to determine its affinities.
