. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. Cranium i>f Cranium of Phyllostoma. The jugal bone is small in most of the bats and very strait. The superior maxillary bone is considerably elongated in this order, particularly in. the frugivorous genera. The difference in this respect which exists between the frugivorous and insectivorous forms is shewn in the cranium of a Pteropus belonging to the former (Jig. 281, 282, 283), and a Phyllostoma to the latter group (Jig. 284, 285, 286). In the former case, the portion occupied by the teeth fully equals in length the portion of the cranium posterior to it; in the latter it is little more than as two to three. The number of teeth con- tained in this bone varies considerably. There is, however, always a single canine tooth on each side, which is tolerably robust and sharp. The molares of the insectivorous Bats are always shorter than those of the frugivorous, and are furnished with sharp points, the latter being truncated and longitudinally grooved. They vary in number from §, to f, or 5. The intermaxillary bones are always very small and short; they contain small incisores, varying in number according to the genera, from two to four in the upper, and in the lower jaw from two to six, there being always either the same numberin the two jaws, or two more in the lower than in the upper; thus there is always one of the following formula;—! \\$. The articu- lation of the lower jaw is transverse. The ascending ramus, with its coronoid process, is large and strong, rising very high above the level of the condyle. The vertebral column.— The cervical verte- bra; are in general very little raised, but they are developed laterally, so as to present the broadest portion of the whole vertebral column,.
