to the vent, tail 15 (imperfect). One of the types, a male, 

 collected by M. EcA'oil, is now in the British Museum. 



This very curious Lizard was originally described as a Uro- 

 mastix allied to U.princeps, O'Sh., which is the type of my genus 

 Aporoscelis. In all respects, except the shape of the tail, it is, 

 however, a true Agama and is well distinguished by its dentition 

 from Uromastir and Aporoscelis, as was first pointed out to me by 

 my friend Dr. Anderson. 



I cannot consider the shape of the tail, in this instance, as 

 warranting generic separation, and following the precedent laid 

 down in dealing with the Iguanoid genera Ctenosaura and Cachrijs 

 (Proc. Zool. Soc. 1886, p. 241), and the Scincoid Egernia (Cat. Liz. 

 iii. p. 134), I have no hesitation in placing Uromasiix baHlliferus 

 in the genus Agama. But it may be regarded as the type of a 

 distinct section or subgenus, for which I propose the name Xen- 

 cif/ama, characterized by the extreme flattening and abbreviation 

 of the tail.

Two specimens, male and female. 60 or 61 scales across the 

 middle of the body. The male has 7 femoral pores on each side, 

 the female 6.

The exclusion of the subocular from the lip and the absence 

 of a light vertebral streak distinguish this Lizard from E. spehii, 

 Gthr. 



17. Eeemias mucronata, Blanf. 



18. Eeemias smithi, sp. n. (Plate XXIX. fig. 4.) 



Head much depressed ; snout pointed, shorter than in E. Iren- 

 neri and mucronata. Upper head-shields rugose ; nasals feebly 

 swollen, lower divided, the nostril pierced between four shields ; 

 frontonasal as long as broad, separated from the rostral ; two 

 prsefrontals ; frontal strongly grooved ; three large supraoculars, 

 second and third forming together an oval disc surrounded with 

 granules ; a small interparietal in contact with a small occipital ; 

 an elongate shield on the outer border of the parietals ; temporal 

 scales granular, smooth ; no auricular denticulation ; lower eyelid 

 scaly ; subocular not reaching the lip, resting on the sixth and 

 seventh labials ; the two first labials in contact with the nasals ; 

 the two anterior pairs of chin-shields in contact. Collar curved,
