144 ME. G. A. BOULENGEE ON THE 



their number is comparatively low (46-54), and so is the number of femoral pores 

 (13-18, only once 19-20). 



In view of the undue importance that has been attached by L. von Mehely and 

 others to certain characters of lepidosis, it will not be without interest to record their 

 variation in this series of over 100 specimens. 



The suture between the internasals is often very short, and in 5 specimens the 

 rostral forms a suture with the frontonasal. The occipital varies much in size ; in 

 some it is very small, in others it is much broader and even longer than the inter- 

 parietal. The suture between the first and second supraciliaries is vertical, at least on 

 one side, in 28 specimens. The series of granules between the supraciliaries and the 

 supraoculars is complete in 30 specimens *. In 9 specimens the parietal is not in 

 contact with the upper postocular, and in 2 it is so on one side only. The masseteric 

 disk is usually large, sometimes small, totally absent in 7 specimens ; in 4 specimens 

 it is separated from the last upper labial by a single granular scale. 4 specimens have 

 five anterior upper labials on both sides, 9 have five on one side only. 



Grey, olive-grey, or pale brown above, with black, brown, reddish-brown, or brick- 

 red markings ; two more or less distinct light streaks on each side, usually very 

 sharply marked in females and young, with a dark band or dark spots between them ; 

 a vertebral series of small dark spots, sometimes confluent into a streak, more often 

 absent than present. Lower parts red, pink, or white in females, salmon-pink or 

 brick-red in males, in which latter a series of azure-blue spots is present on the outer 

 row of ventral shield's ; black spots, if present, small. Tail of young often bluish.

The first specimen on the list has 8 rows of ventral plates instead of 6, the normal 

 number. Scales granular, smooth, or with faint keel ; caudals more or less strongly 

 keeled. Masseteric disk totally absent in two specimens, absent on one side in a third ; 

 in one specimen it is separated from the last upper labial on the right side by a single 

 granule. With one exception, occipital broader than interparietal. 



* This and the preceding character, given by Me'hely in the diagnosis of the ArchteolacertEe (1910, p. 224), 

 thus occur in more than 25 per cent, of the specimens from this part of Spain.
