The coloration, moreover, seems to otter another tangible diflerence. 

 Bouleuger describes E. spekii as being *•' brownish above, with three lon- 

 gitudinal paler lines, and a more indistinct one along each flank f small 

 black cross bars between the light streiks" (Cat. Liz. Br. Mus., iii, 

 X). 84), and Peters also describes the synonymous E. riigiceps as having 

 five longitudinal pale lines, of which the middle one bifurcates anteri- 

 orly, (Monatsber. Akad. Berlin, 1878, p. 203). Our specimens, on the 

 contrary, have G distinct pale lines, the median line, like the other dark 

 interspaces being marked with a series of black spots. The number of 

 these spots averages in each row eighteen to twenty. 



Eremias brenneri Peteks. 



The specimen (No. 20078) collected by Mr. Chanler on the Tana Kiver 

 agrees in all essential points with tlie characters given by Bouleuger 

 in the description of E. brenneri, as distinguished from E. mucronata 

 (Blanford) (Ann. Mus. Geneva (2), xii, 1802, p. 8). It has the upper 

 head-shields strongly striated, and the upper caudal scales strongly 

 keeled. 



Th } specimen seems, in fact, to be perfectly typical, except that it has 

 the anterior three chin-shields in contact, a difterence evidently within 

 the individual variation. The subocular is excluded from the lip, being- 

 wedged in between the sixth and seventh supralabials on the right side, 

 but between the seventh and eighth on the left side. There are, more- 

 over, five elongate infralabials on each side, followed by two or three 

 rows of small hexagonal scales. The top of the head is also normal, 

 but the interparietal is quite minute. With these exceptions, in addi- 

 tion to the strong striation of the upper head- shields, the figures of the 

 head of ^. erytlirosticta given by Bouleuger (Ann. Mus. Geiiova (2), xii, 

 1892, j)l. i., figs. 2a and 2&) would answer for our specimen; that one 

 representing the side of the head is particularly an exact reproduction 

 of No. 20078. 



Eremias hoehneli, sy. uov. 



Diagnosis. — Ventral plates in eight straight longitudinal series; 

 occipital shield present; lower nasal divided, resting on first and second 

 supralabial; supraoculars entirely surrounded by granules; scales on 

 upper surface of tibia much larger than dorsals ; upper head shields 

 strongly striated; subocular reaching the lip; i)osterior chin shields 

 reaching the lip; first pair of infralabials in contact behind the mental. 



Habitat. — Tana Kiver, East Africa. 



Type.—U. S. National Museum, No. 20077; W. A. Chanler coll. 



Remarks. — This species is very closely allied to E. brenneri, with 

 which it shares the strong striation of the upper head shields, the strong 

 cari nation of the upper scales of the tail, the granules surrounding 

 the supraoculars, and the divided subnasal. It difters, however, in 

 having eight longitudinal series of ventrals, instead of six, in the sub-
