Mammalian horizontal cells have generally been assumed to be spectrally non‐selective in their cone contacts until recently, when specific contacts have been found for some species. The rabbit retina is frequently studied as a representative of dichromatic mammalian retinae. These are the reasons for elucidating the connections of the two types of horizontal cells (A‐HCs and B‐HCs) with the green‐sensitive and blue‐sensitive cones of the rabbit retina. Individual A‐HCs and B‐HCs were revealed by Lucifer Yellow injections, the total cone population overlying them was stained using peanut agglutinin, and the blue cones among these were identified by the antiserum JH 455 against blue cone opsin. Both A‐HCs and B‐HCs indiscriminately contact the two cone types available. This holds for the green cone‐dominated dorsal retina and the blue cone‐dominated ventral retina. No evidence was found for a third, potentially blue cone‐selective, horizontal cell type [postulated by Famiglietti, E. V. (1990) Brain Res., 535, 174–179].
