An invaginating bipolar cell that has dendritic terminals forming the central elements of the cone triads is described for the retina of the cat. This type of bipolar contacts a minimum of four or five and a maximum of nine or ten cones. There is no evidence for a bipolar cell which contacts only one cone, i.e., a midget bipolar cell as in simians. There are flat bipolar cells that make superficial contacts with the bases of the cone pedicles and are postsynaptic to between 8 and 14 cones. One cone can be in contact with both an invaginating and a flat bipolar cell. There is evidence suggestive of two kinds of flat bipolars. A comparison is made between the bipolar connections in simians and the cat. The comparison is summarized in figures 29 and 30.
