The fragment of mask on pl. XV is 5⅝ inches high. As before stated, it resembles the mask just described. The mosaic, of large bits of stone, is outlined by a line of single lighter stones. The forehead contains a mosaic of greenish stones, and the space above the ridge of the nose has a patch of light-red shell bits. The space on each side of the nose and in the mouth is painted red, while that above the eyes is painted jet black. A black composition disc is on the temple. The mask without mosaic on pl. XVI is 6⅞ inches high and 5¼ inches wide. The wood is of a light color, and rather soft. We have left on this specimen the tin plate which replaces the missing chin. That this mask was once covered with mosaic decoration may be seen in the fragment remaining at the right side of the mouth. The eyes in this specimen are semi-lenticular in shape, differing from the others which are either ovate or lenticular in outline. This closes our description of the specimens found in the deposit in the cave in the Mixteca. With them were found some fragments of native paper made of _amate_ fiber, two of which enclosed regularly shaped small masses of gum incense. In one of these several pieces of the gum were held together by an interlaced string of flexible bark. They provide further proof that the cave was resorted to for religious ceremonies or sacrifices.

XVII, is the only specimen known from Central America, and with the pieces found recently in the Mexican cave are the only major specimens found under archeological conditions. This mask is 8½ inches high, and the three facial projections extend 4 inches from the face. It is in the Museum of the American Indian, Heye Foundation. This interesting object was found some years ago in a cave in the mountainous region of Honduras, in an arroyo on the headwaters of a small stream flowing into the Rio Chamelecon, about 25 miles from the ruins of the ancient city of Naco. Hundreds of copper bells of varying sizes and shapes were found at the same time. The mask has been figured and described by A. H. Blackiston, whose description follows:
