Diagnosis.—A tiny Sphaenorhynchus without an apparent tym- panum and without vomerine teeth. The absence of the two above-mentioned characters serves to sep- arate S. habrus at a glance from both S. dorisae and S. aurantiacus, the two other species of the genus known to occur in Colombia. Description.—UF 8508 (holotype), from Leticia, Amazonas, Colom- bia. Head moderately broad, width about equal to distance from snout to occiput; snout an obtuse triangle as seen from above, tapering abruptly to a slightly rounded tip; snout pointed and pronouncedly projecting as seen from the side; the eyes very dark and thus standing out prominently against, and through, the milky white skin, but the. ftk Figure 41.—Sphaenorhynchus habrus, holotype, UF 8508 (X 2, except foot and hand, which are X 3)..
