and the anterior border of the tympanum ; occipital region quite flat ; 

 snout obtusely pointed, shorter than postocular part of head ; cheeks 

 swollen in the male ; length of pileus twice or a little more than twice 

 its width. Neck as broad as head. Hind limb reaching the axil, 

 the shoulder, or the collar in the male, the elbow in the female ; foot as 

 long as the head in the male, usually a little longer in the female. Tail 

 cylindrical, 1^ to If times as long as head and body. 



Nostril pierced between the nasal, a postnasal, and the first upper 

 labial. Nasals forming a suture behind the rostral * ; frontonasal 

 broader than long ; frontal as long as its distance from the rostral or 

 the end of the snout. If to If times as long as broad, as broad, 

 behind, as the principal supraoculars or a little broader ; parietals 

 If to 14 times as long as broad, outer border straight or convex, usually 

 not in contact with the upper postocular, or, if in contact, very narrowly.f 

 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 super- 

 ciliaries, the granules sometimes reduced to 2 or 3. J No foramen in 

 the interparietal. § Occipital usually shorter than the interparietal, 

 sometimes broader. 



Eostral not entering the nostril ; a single postnasal ; two loreals, 

 first shorter than second. 4 (rarely 5) upper labials anterior to the 

 subocular, the lower border of which is not or but little shorter than 

 the upper. Temple covered with small scales, as large as or smaller 

 than dorsals, II these scales sometimes feebly keeled ; no masseteric 

 shield ; tympanic shield sometimes moderate, sometimes small, some- 

 times absent ; upper temporal moderately broad, long or short, usually 

 followed by a series of smaller shields.1[ 



No pterygoid teeth. 



* In one specimen examined by Peraooa, the frontonasal touches the rostral 



t More extensively in the specimen of the var. kibonoiensis which I have 

 examined in the Paris Museum. 



X In one specimen examined by 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, absent in a male from the Alluaud Collection 

 in the Paris Museum. 



§ This important character, first pointed out by Degen, is found in one other 

 species of the genus Lacerta, the West African L. echinata, Cope. That it is 

 not to be regarded as of generic importance is shown by the genera Draco, 

 Nucras, and Latastia, where we find the foramen present in some species and 

 absent in others. 



II Larger in specimens from the Kilimanjaro district (subsp. Hhonotensis). 



If Absent in a, female from Kegamaia and in the two males in the Paris 

 Museum.
