Witli a few exceptions, of which the Dcrmopteri and the Lepidosiren are cxamjjles, the intestines are divided into ' small,' and ' large.' The begin- ning of the small intestine, to which is arbitrarily given the name of ' duode- num,' fig. 278, (, fig. 281, c, e, is usually wider than the rest of that di-sasion of the canal: it receives the ducts of the liver and pancreas ; and, in most Osseous Fishes, that of the cajca, fig. 281, d, which are usually termed, from their communication with, or devclope- ment from, the commencement of the small intestine, ' appendices pylorica\' The termination of the small intestine is commonly marked by a circular valve.
