Immediately posterior to it there isa large, elliptical ischiadic foramen, its major axis being parallelto the postpubic style. All the postero-lateral surface of thepelvis is smooth, and withal very much concaved. The elliptical obturator foramen merges largely into the obturator space, the latter running the entire length betweenthe pubic style and the lower border of th^ ischium. The posterior moiety of the pubis is somewhat broader andstouter than the anterior, while it curves mesiad toward the The Emu, Vol: XVIII.

Either one projects posteriorlybeyond the ischium of the same side for at least a centimeter ;both margins of this bone are rounded. There is the barestsuggestion of a prepiihis at the usual site on either side, and it ismost evident in fig. 15 ; it is so minute, however, as to be hardlyworthy of mention. The leading -pelvic vertebra has its body much individualized,while superiorly it fuses with the under surface of the iUa. Thepair of ribs it supports appear to be freely articulated ; but thisis not the case with the second pair. There are six of the leadingpelvic vertebrae that develop lateral processes, which are thrownout to the ventral surface of the ilium upon either side, there tosolidly co-ossify. Opposite the narrowest portion of the preacetabular moiety ofthe pelvis, the sacrum is very broad, and to some degreecompressed. From this locality, however, it gradua
