718 AFRICAN RP:PTILES and BATRACHIANS — STEJNEGER. 



the supraoculars eutirely surrounded by granules (Zool. Auz., xvi, 

 April 10, 1893, p. 115). 



From Bouleno-er's description (Cat. Liz. i>r. Mns., iii, p. 57) our spec- 

 imen differs only in having all the gular granules of the same size, the 

 four posterior rows, including the edge of the collar, suddenly appear- 

 ing as Hat, subeciual scales, while Bouleuger says: " Gular scales mod- 

 erate, gradually increasing in size toward the collar. " 



From Peters' original description and figure (Monatsber. Akad. Ber- 

 lin, 1874, p. 309, pi. — fig. 2) our specimen differs chiefly in having a 

 narrow but elongate interparietal; in having the frenal divided oft" an- 

 teriorly; in having the subocular between fifth and sixth supralabials; 

 and in having only one series of very wide brachial plates covering the 

 outer aspect of the humerus. 



In our specimen the average number of scales across the body is 38; 

 ventral shields in 27 transverse rows; two enlarged median ineanals 

 surrounded anteriorly and laterally by a row of smaller scales ; femoral 

 pores 11 on each side. 



In coloration our specimen agrees very well with Peters description 

 of the type. 



Eremias seztaeiiiata, .sp. uov. 



Diagnosis. — Ventral plates in six straight subequal longitudinal 

 series; lower nasal undivided, resting on first labial only; supraoculars 

 entirely surrounded by granules; upper head-shields strongly striated; 

 subocular excluded from lip by one or two supralabials; back with six 

 l)ale longitudinal bands, including five darker clay colored bands, 

 which contain each a series of numerous black spots. 



Habitat. — Tana Kiver, East Africa. 



Type.— IJ. S. National Museum, No. 20080; W. A. Chanler coll. 



Eemnrks. — Differs from U. spekti chiefly in the exclusion of the sub 

 ocular from the lip and in the coloration. 



Two specimens were collected by Mr. Chanler (Nos. 20079-20080), 

 both having the subocular excluded from the lip by well-di!veloped 

 supralabials, two on both sides of No. 20080, while two on one side and 

 one long one on the other side in No. 20071>. 



On the other hand it appears that the types of J^. spekii (two speci- 

 mens in British Museum) as well as the types of JEJ. rngiceps Peters 

 (how many? Boulenger, Cat. Liz. Br. IMus., iii, p. 84, footnote, says 

 "Types (Mus. Berol. 9287) examined") all have the subocular bordering 

 the lip. 



This character might be supposed to be subject to individual varia- 

 tion, ami I have no material at hand that will throw any light upon 

 this subject, but I find that Boulenger {torn, clt.) when describing 

 species of which British Museum contains very large series (for instance, 

 E. (fKttiflafa, PI). 88-89, 28 si)ecimens; E. an/i(ta, p. 102, 28 specimens) 

 does not mention any variation in this character, although he always 

 notes the irregularities in the numbers of the adjoining supralabials.
