Fejérváry, G. J.: Notes on a very little-known lizard: Lacerta princeps Blanf., with description of the male specimen preserved in the Vienna Natural History Museum
Two superposed postnasals, the lower one almost entirely upon the first supralabial, only its lower posterior corner joining the second supralabial; lower postnasal somewhat larger than upper one; in the young described by DE MÉHELY the lower postnasal is said to rest merely upon the first supralabial. First loreal meeting the frontonasal and forming a rather long suture with the prefrontal; widely separated from the rostral by the upper postnasal. Median length of second loreal nearly equalling its distance from the superior end of the suture between rostral and first supralabial; in the young this length equals, according to DE MÉHELY, the distance between the 2 nd loreal and the hind border of the nostril. Two preoculars on both sides, the first larger than the second, especially the latter one being strongly keeled; the keel proceeding to, and continuing upon, the subocular, forming the upper edge of it, which is ventrally delimited by a deep and broad furrow; both the keel and the furrow are vanishing caudad; in DE MÉHELY'S specimen the occurrence of a single preocular is stated. Four upper labials anterior to the subocular which is considerably narrower beneath than above; three well developed supralabials posterior to subocular. Temple covered with large, polygonal shields; masseteric distinct on the right, less visible on the left side, separated from postoculars and supratemporals by a single, and from the tympanic by a double, row of shields; on the right side 1, on the left side 2 rows of shields separating the masseteric from the supralabials; tympanic comparatively small; the same features occur, though less pronounced, in the young in the female examined by BOULENGER; a small shield separates the tympanic from the 2 nd supratemporal. 2 large supratemporals, 1 ST not much larger than 2 nd ; no post-supratemporal granule, which is contrary to what I have found obtaining in all of the Massive Lizards known to me. 36 scales across the middle of body; 34 in BLANFORD'S, 37 in BOULENGER'S, and 35—36 in DE MÉHELY'S specimen; scales granular on the nape, with faint trace of a top-keel, smooth on the sides of the neck. Scales on back large, subimbricate, very strongly keeled; the keels are rather mesial than diagonal in position, which is contrary to the respective statements of BLANFORD, BOULENGER and DE MÉHELY; according to the latter author the keels are converging caudad towards the axis of the body; in the Vienna male I found the keels to be rather longitudinally subparallel. With respect to the occurrence of keels as sharp as that, L. princeps is, within its genus,
