frontalis fron·ta·lis (frŭn-tā'lĭs)
Sitta frontalis corallipes (Sharpe): Velvet-fronted Nuthatch.
For instance Plotheia frontalis, a Noctuid which often abounds in Ceylon, shows an equally bewildering wealth of forms.
The common nuthatch of the Nilgiris is the velvet-fronted blue nuthatch (Sitta frontalis).
Dorsal surface sooty black as in stelleri, but with blue on forehead nearly as extended as in frontalis.
Some months previously to his coming under observation he developed a convulsive tic limited to the frontalis.
