(After Edinger.) (b) Elasmobranchs.—In elasmobranchs the bulging corpora striata, which even grow into the lamina terminalis, and the dominant olfactory lobes constitute the bulk of the telencephalon (Figs. 647 and 653). From each olfactory lobe there extends forward a conspicuous olfactory stalk, ter- minating in an olfactory bulb which may be quite large. The velum inter- positum, the thin roof of the third ventricle, develops an invaginated trans- verse fold, or velum transversum, which marks the posterior limit of the dorsal part of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Walter, Herbert Eugene, b. 1867; Sayles, Leonard Perkins, 1902-.
