II II 9 RESPIRATORY SPACES OF THE LUNGS 341 The respiratory epithelium of Tropidonotus natrix consists of twokinds of cells, namely, small, nucleated ones, which are always groupedin the intercapillary spaces, and large, flattened ones, which containno nuclei and connect the islands of small cells. These groups or islandsof small cells almost never fill up the whole of an intercapillary space,so that large cells come to lie totally or partly in them also. Here andthere one perceives an intercapillary space filled up with two groupsof small cells divided by flattened cells. It is rarer to find spaceswhich contain only large cells. The groups of small cells in the spacesoften form quite peculiar, irregular figures with very acute angles. Inrare cases one finds the groups of two neighboring spaces connectedby small cells, which run over the intervening capillaries. The num-ber of cells, of which a group consists, varies between two and thirty. Elenzs pictures show that the intercapillary
