"New species of lizards are described from the Talamanca Mountains of Costa Rica and western Panama. Anolis fungosus, from lower montane rain forest of the Atlantic slopes, is a tiny, fungus-patterned anole with a pair of bony parietal knobs on the rear of its head. Anolis vociferans, which lives on the drier Pacific slopes and squeaks when handled, undergoes an ontogenetic transformation of the ventral granules--from obliquely conical and juxtaposed to keeled and imbricate. Both species appear related to the lowland Anolis pentaprion Cope, and a pentaprion species group is defined. Evolution within the group has included selection for lichenose and fungous camouflage; on the basis of osteology, color pattern, and scale features, A. vociferans is suggested as the most primitive member and A. fungosus as the most divergent. Notes are presented on the distribution, variation, behavior, and synonymy of Anolis pentaprion Cope, 1862; a lectotype is designated for the nominal Anolis panamensis Boulenger, 1890. A Colombian species, Anolis sulcifrons Cope, 1899, is resurrected from the synonymy of pentaprion. The importance of describing dewlap color in anoles is widely recognized, but collectors are also urged to record the coloration (or absence thereof) of the iris, the tongue, and the throat lining"--P.
