The glycoproteins of the intestinal mucosa of five vertebrate species including fishes (Sparus auratus), amphibians (Rana perezi), reptiles (Testudo graeca), birds (Gallus gallus) and mammals (Mesocricetus auratus) were studied by means of methods of lectin histochemistry. Goblet cells of the intestine showed different lectin binding patterns depending upon the location in the villi. Thus, goblet cells located in the intestinal glands presented a different reactivity from that of the goblet cells located at the tip of the villi. Differences in lectin stainings between small and large intestines were more marked in higher than in lower vertebrates. WGA binding sites were the most abundant throughout the intestinal mucosa of the animals studied. Golgi areas of the different cell types studied were frequently reactive for DBA and SBA. The results obtained in the Brunner's glands of the hamster were similar to those obtained in other mammals, suggesting a common mucin composition. In the hamster intestinal glands, Con-A stained the Paneth cells.
