1. _Benedict, Charles County._—More than 50 years ago Cope (Proc. Nat. Sci. Phila., 1867, p. 155) reported the finding of peccary jaws mingled with remains of Miocene vertebrates collected by James T. Thomas, near his residence in Charles County, not far from Patuxent River, near Benedict. Cope recognized that the peccary and a part of a jaw of _Grison macrodon_ (referred by Cope to _Galera_) belonged to the Pleistocene. The peccary was referred to the existing species _Dicotyles (Tagassu) torquatus_; likewise their similarity to the remains described by Leidy from Charleston, South Carolina, was noted. They are assigned here to _Tagassu lenis_. The jaws from the Patuxent locality are now in the Academy of Natural Sciences at Philadelphia. 2. _Chesapeake Beach, Calvert County._—Mr. William Palmer, of the U. S. National Museum, has shown the writer 3 teeth of a peccary secured at the place named. These will be mentioned in the discussion of the geology of the locality. A left third premolar is 10.3 mm. long and 6.2 mm. wide. A left second molar is 12 mm. long and 10 mm. wide. These apparently belonged to _Tagassu lenis_. In March 1921, Dr. Adolph H. Schultz, of the Johns Hopkins Medical School, presented to the U. S. National Museum a part of the left ramus of the lower jaw of a peccary found at Chesapeake Beach. This fragment contains the first and second molars and the sockets of the fourth premolar and the third molar. This jaw and the teeth have been compared with the corresponding parts of a specimen of _Tagassu angulatus_ (No. 35815, U. S. Nat. Mus.), secured along the boundary between the United States and Mexico. In size the fossil teeth differ little from those of _T. angulatus_; the first molar is, however, somewhat wider; the conule between the two hindermost cones, the hypoconulid, is much smaller than in the existing peccary used for comparison. The inner face of each tooth is not so flat in the fossil as in the other species. In the fossil the height of the jaw at the second molar is 28 mm.; in _T. angulatus_ 35 mm. The specimen is referred to _Tagassu lenis_. 3. _Corriganville, Allegany County._—In a rock crevice 3 miles west of north of Cumberland, J. W. Gidley found abundant remains of peccaries. These were described by him in 1920 (Proc. U. S. Nat. Mus., vol. LVII, pp. 651–678, plates LIV, LV, 13 text-figs.). He recognized 4 species, 2 belonging to _Platygonus_ and 2 to _Mylohyus_. The new species, _Platygonus cumberlandensis_ and _P. intermedius_ and _Mylohyus exortivus_, are based on materials found in the fissure. With the other materials he recognized a part of a lower jaw, which he referred to _M. pennsylvanicus_.
