coat·ed pit

specialized depressions on the cell surface involved in receptor-mediated endocytosis; the visible proteinaceous layer on the cytosolic side of the depression provides the coated appearance.

A specialized depression on the cytoplasmic face of the cell membrane, lined by a ‘scaffolding’ protein, clathrin. Coated pits are the 1st stage in forming a coated vesicle, which internalises and degrades receptors for VIP, insulin and other hormones. Coated pits are involved in hormone receptor-mediated endocytosis, and are pivotal in down-regulating hormone activity

Coated pits were seen on the apical cell surface and nearby were large coated vesicles (Figs.
To these authors, there are two main vesicles involved in transport of substances into cells, that are derived from surface membrane invaginations and are called coated pits. Coated pits are invaginations braced by special membrane-associated proteins and are used to bring material into the cell for further processing.
Probably, as related by Stevens & Lowe, the coated pits became coated vesicles in the cytosol.
Coated pits, coated vesicles, and receptor-mediated endocytosis.
