1 tails, so that we are, to-day, in an absolute want of a reliable, comprehensive work on the matter. The foramina on the maxillary of Lizards are the outlets for the rami gingivales & cutanei given off by the ramus alveolaris superior — represented, in this Order, by a single nerve — of the nervus infraorbitalis, which is the second branch of the nervus maxillaris, viz. of the Und nerve originating from the trigeminus stem. The correct name of these foramina is, thus, foramina maxillaria pro exitu ramorum gingivalium & cutaneorum rami alveolaris superioris nervi infraorbitalis, or, briefly, foramina maxillaria gingivalia 6c cutanea. They are known, in osteological literature, as „foramina alveolaria", an accepted, though unprecise term, the suppression of which is, hence, to be recommended. The artery passing the canalis maxillae pro ramo alveolari superiori n. infraorb. is the artéria alveolaris superior — referred to by C. K. HOFFMANN 44 as „A. dentalis superior" — belonging to the sphenomaxillary complex of the artéria maxillaris interna given off by the art. carotis externa. Its rami gingivales, and cutanei — for, apperently, such are also present — are going through the foramina gingivalia & cutanea maxillae. May be however, that the small artery branches passing through the foramina cutanea of the maxillary, lying above its foramina gingivalia, are sent off by the artéria infraorbitalis, constituting, thus, inlets instead of outlets as far as angiological conditions be concerned, a supposition based on the topographical conditions related to the course of the artéria infraorbitalis in Lizards, as well as on the fact that some small branches of the art. alveol. superior posterior of Mammals — man, e. g. — exhibit the tendence to fuse with adjacent branches of the art. infraorbitalis. These conditions point toward the necessity of a close examination of the relation existing between the branches sent off by the ramus alveol. sup. n. infraorb. and those taking their origin from the same nerve (n. infraorb.) in its more terminal course, i. e. rostrad from the origin of its superior alveolar ramus. It is possible, that such investigations will prove that some of the maxillary foramina here dealt with have to be looked upon also from a neurological point of view as inlets, and not as outlets, an anatomical difference to which no sufficient attention has been paid during osteological work. The terminological conclusion to be drawn from such neurological conditions would 44 In: H. G. BRONN'S Klassen u. Ordn. d. Thier-Reichs, VI, III. Abth., Rept, II. Eidechsen u.
