by having anteriorly directed paroccipital processes that follow the curvature of the auditory bulla, and having a postorbital process of the zygomatic arch comprised primarily of the jugal. The upper toothrows diverge strongly posteriorly, with left and right PM4 nearly meeting at the midline. The individual teeth exhibit coronal hypsodonty, have welldeveloped roots, and a planar occlusal surface. Each consists of four transverse lophs, with both an anterior and posterior pair separated by a deep median flexus but joined lingually and thus form a distinctive Y shape; the two pairs of lophs are separated by a transverse flexus that extends completely across the tooth (fig. 114, left). Both the individual lophs and lingual confluence appear narrower, and with sharper corners, in

heard in middle and lower reaches of the Rio Jurua´. The latter expressed no more than five to 10 individual pulses in a given vocalization, with an average of about seven. Call structure varies extensively throughout Amazonia (Emmons, 1981; Emmons and Feer, 1997), but is organized geographically into high or low pulse numbers that likely correspond to the two species we recognize here (P. Santos, J. Podos, and M. N. F. da Silva, unpubl. data). The two species likely encounter one another somewhere along the upper Rio Juruá between our Upper Central sampling sites and Cruzeiro do Sul (fig. 1). We did not travel this section of the river, and thus have no notes on the nature of vocalizations through this area.
