XLV. — Descriptions of new Species of Lizards and Frogs 

 collected by Herr A. Forrer in Mexico. By G. A. 



Boulenger. 



Eumeces Bocourtii, sp. n. 



Head small, its length (from end of snout to posterior 

 border of interparietal) contained nearly six times in the 

 distance from end of snout to vent; snout* ,short, obtuse; 

 cheeks not swollen. Limbs as in E. Skiltonianus. Head- 

 shields as in the latter species, but the postnasal smaller, 

 smaller (or at any rate not larger) than the nostril ; two pairs 

 of occipitals ; postmental not divided. Scales of body equal, 

 in twenty-six longitudinal series; fifty-two or fifty-six trans- 

 verse series from occipitals to base of tail ; no enlarged cer- 

 vical scales. Two large prseanal scales. Tail without enlarged 

 inferior series of scales. Bronze-coloured above, yellowish 

 beneath, the belly washed with greenish ; a brown band along 

 each side of head and body, passing through the eye and above 

 the ear ; on the head and neck this band is bordered above by 

 a rather indistinct yellowish line ; eight longitudinal series of 

 dorsal scales between the two brown bands.

Uta {Phymatolepis) lateralis, sp. n. 



Size and proportions of Phymatolepis bicarinatus 7 A. Dum., 

 from which it is distinguished by the following characters : — 



The frontal is divided in the middle by a transverse suture, 

 and in contact posteriorly with the large occipital, thus sepa- 

 rating the two fronto-parietals. 



The two vertebral series of keeled scales formed of much

larger, more strongly keeled, and still more regular scales, 

 the length of one of these scales measuring more than halt 

 the vertical diameter of the ear-opening ; the two series bor- 

 dered on their inner and outer sides by smaller keeled scales. 

 No scattered keeled scales among the granules of the back, 

 but a lateral series of irregular keeled scales from the neck 

 to above the hind limb.
