Scutel´lum, n.; pl. scutella. Scale. Any one of the divisions into which the podotheca may be broken up by regular lines of impression; especially such divisions when large and in regular vertical series; various smaller divisions being called reticulations. Scutella occur especially on the anterior face of the tarsus and top of the toes; often also on the back of the tarsus; sometimes they completely encircle the tarsus. When thus large, some ornithologists call them scuta; then using scutella for the smaller irregular reticulations. Scutella are sometimes obsolete. (Commonly, but erroneously, written scutellæ.)
