56 MR. G. A. BOULENGEE ON LIZAEDS 



1| to 1| times as long as broad, outer border convex, usually not in contact 

 with the upper postocular, or, if in contact, very narrowly. Of the two major 

 supraoculars, the first is the longer ; 5 or 6 superciliaries, the suture between the first 

 and second oblique ; an incomplete series of granules between the supraoculars and 

 the superciliaries, the granules sometimes reduced to 2 or 3 *. No foramen in the 

 interparietal f. Occipital usually shorter than the interparietal, sometimes broader. 



Rostral not entering the nostril ; a single postnasal ; anterior loreal shorter than 

 second. 4 (rarely 5) upper labials anterior to the subocular, the lower border of whicli 

 is not or but little shorter than the upper. Temple covered with small scales, as large 

 as or smaller than dorsals J, these scales sometimes feebly keeled ; no masseteric 

 shield; tympanic shield sometimes moderate, sometimes small, sometimes absent; 

 upper temporal moderately broad, long or short, followed by a series of smaller 

 shields §. 



No pterygoid teeth. 



21 to 26 [I gular scales in a straight Hne between the symphysis of the chin-shields 

 and the median collar-plate, these scales strongly increasing in size towards the collar ; 

 gular fold more or less distinct. Collar even-edged or very slightly serrated, composed 

 of 7 to 10 plates. 



Dorsal scales rhombic-hexagonal, more or less distinctly keeled, juxtaposed or sub- 

 imbricate ; laterals a little smaller, feebly and diagonally keeled, or nearly smooth. 

 37 to 43 scales across the middle of the body ^ ; 23 ( $ ) to 35 ( rf ) scales, in the 

 middle of the back, corresponding to the length of the head, 2 or 3 on the sides 

 corresponding to a ventral plate. Ventral plates in 8 longitudinal series, the second 

 series on each side from the median line much broader than the others, the outer 

 series composed of very narrow plates ; 23 or 24 transverse series in males, 27 or 28 

 in females **. Prtieanal plate laige, with one or two semicircles of smaller plates, 

 one of the median of which is more or less enlarged, and may be described as a second 

 prseanal. 



Scales on upper surface of tibia smaller than dorsals, strongly keeled. 22 to 26 

 lamellar scales under the fourth toe. 16 to 20 femoral pores on each sideff. 



* In one si>ecimen examined b}' Peracca the series of granules is complete on one side and totally absent 

 on the other. The series is complete in one of the specimens described by Sternfeld. 



t This important character, first pointed out by Degen, is found in two other species of the genus Lacerta, 

 the East Afrioan L. vaueresdli Torn, and the West African L. echinata Cope. That it is not to bo regarded 

 as of generic importance is shown by the genera Draco, Sucras, and Latastia, where we find the foramen 

 present in some species and absent in others. 



i Larger in specimens from the Kilimanjaro district (snbsp. lihonotensis Liinub.). 



§ Absent in a female from Kakumega. 



II Up to 28, according to Degen and Sternfeld. 

 ^ 32 to 39, according to Peracca and Sternfeld ; up to 49, according to Degen. 



** 23 to 25 in males, 24 to 28 in females, according to Peracca, Degen, and Sternfeld. 



tt 14 to 20, according to Peracca and Sternfeld.
