Lacerta. 307 



Ver. Magdeb. f. 1896-1897, p. 7) is probably based on some aberrant 

 specimen of L. danfordn. 



In all probability L. Icevis is directly derived from a form closely 

 related to L. hrandtii. There is not a single cbaracter that can be 

 said to be opposed to such a derivation. 



23. LACEETA JATAKAEI. 



Lacerta jayaJcari, Bouleng. Cat. Liz. iii, p. 40, pi. ii (1887), and Tr. 

 Zool. Soc. xxi, 1916, p. 64, pi. iv, figs. 6, 7. 



Head and body moderately depressed. Head 1| to if times as long 

 as broad ; snout pointed, as long as postocular part of head ; depth 

 of head in the tympanic region equal to the distance between the 

 anterior corner of the eye and the tympanum ; cheeks rather swollen 

 in the male ; pileus 2i to 2i times as long as broad. Neck slightly 

 constricted. Hind limb reaching the collar or a little beyond in the 

 male, the axil or the shoulder in the female ; foot as long as the 

 head or a little longer. Tail cylindrical, a little more than twice 

 the length of head and body. 



Nostril pierced between the nasal, two postnasals, the first upper 

 labial, and the rostral. Nasals forming a rather long suture behind 

 the rostral ; frontonasal as long as broad or a little broader than long ; 

 frontal usually shorter than its distance from the rostral, 1 1- t-o 1^ 

 times as long as broad, as broad, behind, as the major supraoculars 

 in the adult (narrower in the young) ; parietals 1^ to 1^ times as 

 long as broad, with straight or slightly convex outer border, not in 

 contact with the upper postocular ; occipital usually as long as and 

 much broader than the interparietal, sometimes shorter and but little 

 broader. Major supraoculars, of which the first is usually the longer, 

 separated from the superciharies by a complete series of granules ; 7 

 to 9 superciliaries, the suture between the first and second sometimes 

 vertical, sometimes oblique. 



Rostral largely entering the nostril ; two superposed postnasals ; 

 two loreals, first much shorter than second ; 6 upper labials anterior 

 to the subocular,* the lower border of which is usually but little 

 shorter than the upper. Temple covered with minute granules, which 

 are smaller than the dorsal scales ; the granules in front of the ear 

 may have a tendency to form a denticulation ; no masseteric shield ; 

 tympanic shield usually well developed, sometimes very small ; a large 

 anterior supratemporal shield, in contact with the fourth supraocular, 

 followed by a series of 2 or 3 smaller shields. 



* 7 on one side in one of the specimens.
