The bones are all very thin in spots. Temporal ridges indistinct. The left parietal bone is somewhat higher than the right one, while the length of the two is nearly the same. Infero-superiorly at middle left 4.8, right 4.65 cm. Antero-posteriorly at middle "4.7 "4.7" IV. Rssum1i. Numbers.--Among the 391 Old World and American monkeys examined by me 52, or 13.3 per cent., show some form or other of anomalous parietal division. According to the species of the monkeys, the proportions of cases with division are as follows: Among the 17 previously reported cases of monkeyswith complete or incomplete parietal divisions, there are 13 Old World (1 Cynocephalus, l 8 Cercopitheci, 3 Macaci, and 1 Semnopithecus) and 4 New World monkeys (2 Cebi, 1 Mycetes, 1 Arctopithecus = Hapale). The Old World monkeys show in general a considerably larger proportion of complete, but a smaller proportion of incomplete, divisions than the American ones. If we count all the divisions together, their proportions in my two series of cases (there are no data as to the number of cases examined in other instances) are almost equal (12.8 % in the Old World, 14.4 % in the American monkeys); but such a combination and comparison are not fully justifiable: they would imply an equivalence of the divisions which cannot thus far be clearly proven. The proportion of the anomalies under consideration differs quite markedly in the various species of monkeys. Divisions of various nature are comparatively very frequent in the Macaques, particularly the Macacus rhesus, and quite frequent in the Cebi and Ateles, but rare in...
