. Bulletin - United States National Museum. Science. Fig. 41.—Dorsal view of unguals of Stegosaueus. 1, Ungual of hind foot. Cat. no. 7419, Juvenile 2, of digit I, forefoot. Cat. no. 4937, , Type of Stegosaubus sulcatus Maksh. 3, Ungual of DIGIT I, FORE foot. CAT. NO. 7401, JUVTimLE. ALL FIGURES I SIZE. These unguals are flattened, hoof-like bones that during the life of the animal were doubtless incased in a horny nail. The specimens with which two unguals have been found show that they are of two styles, one of which is as broad as long, the other more elongated. The relative shape and size of these unguals are well shown in figure 41. From the position in the rock of the elements pertaining to the right fore foot of No. 4934, I am led to believe that the elongated ungual (1, fig. 41) belongs to digit I. In old individuals the surfaces of these bones become very much roughened, and the lateral, posteriorly directed points shown in figure 41, 1 and 3, continue to ossify until they project posterior to the articular end as blunt rounded points (fig. 41, 2). Belonging to the fore foot of No. 7401 are other elements which from their close resemblance to some of the reduced terminal phalanges of Eleplms are con- sidered the final ones of the remaining digits. Antero-posteriorly these are A^ery.
