Show 288 MR. W . A. FORBES O N THE GREAT ANTEATER. [Mar. 7, The tip of the tongue is quite glabrous and globular ; but the greater part of the rest of its extent, anterior to the pair ot circumvallate papillae, is dorsally and laterally covered with similar, but smaller, retroverted papilli, best developed towards the tip of the organ, and gradually getting smaller and smaller towards its base, till they are scarcely'visible to the unaided eye except in certain lights. There is a median glabrous line, or shallow groove running along the Fig. 1. Palate of Myrmecophaga jubata; from a preparation in the Museum of the Royal College of Surgeons, prepared from specimen a. tongue till near its apex; but this is ventral in position. According to Owen there is a similar dorsal one; but if so, it is not very evident (I. c. p. 129). The dorsal surface, however, is slightly fluted towards the apex. In front of the circumvallate papilla? a slightly raised median longitudinal ridge extends for some 5 inches. M y observations on the salivary glands agree well in most points |
