354 MR. G-. A. BOULENGER ON THE VARIETIES OF 



little shorter, sometimes a little longer, as long as or a little longer than the fronto- 

 parietals 1 ; parietals once and one-fourth to once and a half as long as broad, usually 

 in contact with the upper postocular 2 , the outer border never distinctly concave for the 

 reception of the supratemporal. A female specimen from Voslau, near Vienna, is remark- 

 able for the very regular division of each parietal into two by a transverse suture 

 (PI. XXV. fig. 4). Occipital usually shorter than, and as broad as or narrower than, 

 the interparietal, but sometimes as long as the latter and not rarely broader 3 ; a small 

 additional shield not unfrequently intercalated between the two. A series of granules 

 between the major (second and third) supraoculars and the supraciliaries ; the first 

 or the first and second supraciliaries usually in contact with the second supraocular 

 (PL XXV. fig. 1), but the series of granules sometimes complete, extending from the 

 first supraocular to the upper postocular. 



The specimen from near Vienna, noticed above as having the parietal shield 

 divided, is further anomalous in the total absence of the first supraocular (PL XXV. 

 fig. 4). Postnasal single 4 ; nasal usually separated from the anterior loreal by the 

 postnasal 5 . Temporal scales small, often granular ; masseteric disk and tympanic 

 shield nearly always present 6 ; masseteric disk usually large, round or oval, and 

 separated from the parietal by a supratemporal shield or one or two, rarely three, series 

 of scales. Four upper labials anterior to the subocular, very rarely three or five, 

 and on one side only ; subocular very variable in shape 7 . 20 to 30 scales and granules 

 in a straight line between the symphysis of the chin-shields and the median collar- 

 plate; gular fold usually distinct, indicated by one, two, or three series of minute 

 granules. Collar without, or with merely a trace of, serration, composed of 7 to 12 

 plates, usually 9 to 11 (not including the outer, smaller plates which are separated 

 from the edge by granules). 



Scales on body granular, juxtaposed, round or oval-subhexagonal, more or less 

 distinctly keeled, rarely smooth s , often a little larger on the back than on the 



1 Shortest frontal, measuring only three-fifths its distance from end of snout, in a male from St. Malo 

 (PI. XXV. fig. 3). 



2 Exceptions in three specimens from Glenan Isles and in three from Eaux-Bonnes. I must here correct a 

 lapsus in my description of Laeerta depressa (P. Z. S. 1904, ii. p. 333) where "upper supraocular" should 

 read " upper postocular." 



3 Occipital very minute, almost reduced to a granule, in one specimen from Dinant. 



4 Absent, fused with the anterior loreal, in a specimen from St. Malo ; divided into two in a female from 

 Paris (Lataste Collection). 



s Exceptions, in which the nasal joins the anterior loreal above the postnasal, are not at all unfrequent. ; 

 I have noticed them in specimens from St. Malo, Glenan Isles, Eaux-Bonnes, Odilienberg, and Banda. 

 c Absent in a specimen from St. Malo and in one from Eaux-Bonnes. 



7 Its lower border sometimes as long as its upper border, a character which has been given as diagnostic of 

 L. depressa. 



8 In two specimens from Dinant, Belgium.
