Reimtrl's.—The family Khinopomidie is strikingly characterized by the presence of two phalanges in the second finger, the small trochiter of the humerus forming no secondary articula- tion with the scapula, the free premaxillaries from whicli the i)alatal branch is nearly lacjc- ing, and the absence of 2)ostorbital processes. The strongly primitive shoulder joint, ditier- ing from that of the Megachiroptera merely in the greater size of the humei'al tuberosities, as compared with the head of the l)one. indicates a low position for the group. This is con- firmed bv the retention of two distinct pha- langes in the second finger, a character not found elsewhere in the ]Microchiro[)tera, and by the free premaxillaries closely resembling i'"^- ii-Rhinop<.ma miceo- ,1 J- jl -r»j -1 I ,1 ' ... rHYLLl'M.

A similar conclusion was reached by Peters, and addi- tional evidence in its favor has been brought forward by AVi
