In Nycticorax the supraoccipital region is carried to a point above, and is usually divided by a pronounced crest with rounded summit. A far broader strip separates the crotaphyte fossoe from each other in the median line. 'I'he occipital condyle, although of the same shape, is relatively much smaller, and finally the posterior orbital peripheries can be seen peeping above the parietal domes, all these differences enumerated giving to these two skulls, even when only casually compared from this view, a very dissimilar look. In a number of minor details, principally referable to relative posi- tion and form, the points for examination within the braincase present certain differences between the Night Herons and the genus Ardea. All the essential characters in the skull of Nycticorax n. iicevius agree with the corresponding ones in the skull of Ardea herodias, as they. Fu;. 8. Right lateral view of the sternum of Ardea herodias. Natural size, and same bone as shown in Figure 7. have been described above. The skull of the former, however, is about one-fifth less in point of size than it is in the last named species. (See Fig. 29.) The vHifidihle of the Herons offers us a number of points of interest for our 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 Carnegie Museum; Carnegie Museum of Natural History.
