LITERATURE on villus pattern in the rhesus monkey is scarce. Lineback1 noted, using ordinary histological methods, that villi were flange-shaped in the duodenum and that towards the lower end of the ileum they attained a more typical finger-like form. It is, however, difficult to decide firmly about the shape of villi without dissection microscopy. Booth et al.2 pointed out that leaf-like villi may appear finger-like in a histological section depending on its plane. This communication reports on the configuration of intestinal villi in apparently normal rhesus monkeys utilizing the technique of dissection microscopy.
