ttaching any age significance to its absence from the Angels Peak faunule. It should be mentioned, however, that no remains of _Haploconus_ were reported as a result of the more extensive collecting by Granger in the Angels Peak area. Incidentally, the type of _Haploconus angustus_ is said to come from near Huerfano Peak (Matthew, 1937:156). The high ratio of carnivores to ungulates is a peculiarity shared with, but far exceeded by, the Lebo fauna if figures obtained from surface collections of the latter are used. It seems unlikely that this ratio is the result of selective trapping in the accumulating sediments. Perhaps, this high ratio reflects the imperfectly carnivorous habits of the Paleocene creodonts as a group. One obvious explanation, regardless of probability or merit, is that some of these do not belong to the Carnivora. The percentage composition of the Angels Peak faunule based on 148 identifiable mammalian specimens, is as follows: Percent Insectivora: 5 Carnivora: Arctocyonidae: 32 Miacidae: 4 --- 36 Condylarthra: Hyopsodontidae: 22 Phenacodontidae: 18 Periptychidae: Anisonchinae: 10 Periptychinae: 5 --- 15 --- 55 Others: 4 ---- 100 The most common forms in the Angels Peak faunule are: _Tricentes_ cf. _T. subtrigonus_, _Chriacus truncatus_, _Ellipsodon acolytus_, _Tetraclaenodon_ nr. _T. puercensis_, and _Anisonchus sectorius_. Post-cranial skeletal elements are of relatively rare occurrence in the pocket. The presence of several more or less complete skulls, and the relatively frequent association of upper and lower dentitions, however, seem to be points against ascribing the accumulation to the activities of predators and scavengers, otherwise perhaps indicated by the large amount of resistant tooth material. AGE OF THE FAUNULE The Angels Peak faunule, as Granger stated, is of Torrejonian age. This fact is clearly evident for the genera are all, with the exception of the forms referred to the Primates, represented in beds of that age elsewhere in the Nacimiento. Further, approximately two-thirds of the known "Torrejon" genera are recorded by specimens from the Angels Peak pocket. The primate remains
