I, II, and VI, figs, i, 12, 39 and 40; Ven.).—The ventricle, which is 42 mm. long by Ven. Fig. 27 mm. wide in this specimen, is shaped something like a 4- sided pyramid. Beginning bluntly, it gradually increases in width and then rapidly tapers down into a posterior apex. The ventricle has one more layer than the auricle. Outside is the.
