The figure of the deity shown in pl. XXXVII is in the Vienna Museum. It has been described by Dr. Heger, who has kindly sent me a number of photographs of the object, and some details regarding it. This has been identified by Dr. Seler as representing the god Xolotl, one of the deities or guardians of the Tonalamatl.[107] The specimen does not contain much mosaic decoration, being of highly polished wood. It is 3½ inches high and 2¾ inches broad. Dr. Heger has courteously sent me the following notes concerning the specimen: The posterior circular cavity (see side view) is partly filled with a resin-like mass, by means of which the piece must have been fastened to some other object. Vestiges of this resin-like substance are found in all the hollowed places where today some of the inlay is missing, as in each of the three rounded oval incurvations, of both lateral walls, in which probably small heads [of mosaic?] were also incrusted. The eyes and the six small teeth consist of milk-white shells; the two hook-like canines consist of white mother-of-pearl-like shells. The two large ear-lobes, as well as the inferior part of the nasal septum, are perforated transversely. The pretty little human head at the navel of the figure probably consists of pitch-black obsidian. The ear-pendants are missing on the left side. The pupils of the eye (right one missing) are enclosed in small rings of mother-of-pearl. Projecting from the opened mouth, there is above the red tongue another small white shell-plate with three sharp downward points (teeth). The little head shows injury in several places.

XXXIX A B KNIFE HANDLES OF WOOD WITH MOSAIC DECORATION PREHISTORIC AND ETHNOGRAPHIC MUSEUM, ROME] _Knife Handles_ The next group of objects to be noted consists of knife handles. The beautiful specimen on pl. XXXVIII is in the British Museum. It is a chipped leaf-shape bladed knife of honey-colored chalcedony. The handle is of a soft, light-colored wood, carved in the form of a crouching human figure. The actual socket in which the blade is fixed proceeds from the chest of the figure, which grasps it with a hand on each side, and rests his chin on the top. The socket is firmly bound with cord. The figure and the socket up to the binding have been covered with a mosaic, chiefly of turquois, varied with malachite and white, pink, purple, and orange shell, as well as a few pieces of pearl shell. Much of the mosaic has disappeared. The figure wears an eagle mask, the face appearing in the open jaws. This knife, which measures 12½ inches in length, is one of the most artistic of mosaic specimens. [Illustration: FIG. 19]
