Electrical responses of the retinas of 4 species of microchiropteran bats stimulated by spectrally restricted light flashes were found to diverge systematically from the rhodopsin absorption spectrum. The divergence was progressively greater across the 4 species. The results appeared explainable by assuming a second photoreceptor class and photopigment which was present in progressively greater numbers in the retinas of Eptesicus fuscus, Desmodus rotundus, Artibeus jamaicensis and Carollia perspicillata.
研究发现，受光谱受限的闪光刺激时，4种小型食虫蝙蝠视网膜的电反应与视紫红质吸收光谱存在系统性差异。在这4种蝙蝠中，这种差异逐渐增大。通过假定存在第二种光感受器类型和光色素，且在棕蝠、吸血蝠、美洲果蝠和食果蝠的视网膜中数量逐渐增多，这些结果似乎可以得到解释。
