roundinii' them, two of them transverse and posterior, and two longi- 

 tudinal and anterior. Tliree rows of brachial plates, the anterior 

 continuous with the posterior of two rows of antebrachials. No 

 postantebrachials. Four rows of plates on inferior side of femur at 

 middle, and two rows on inferior side of tibia. 



Color above dark brown, with three narrow yellowish stripes on 

 each side, which proceed respectively from the temple, and from the 

 superior and inferior borders of the tympanum. The inferior stripe 

 is more or less broken into elongate spots. The space between the 

 superior and median stripes is marked by black cross-bars, and a 

 row of black spots extends along the inner side of each of the supe- 

 rior stripes. A light stripe on the posterior face of the femur, which 

 is continued on the tail. Below this stripe on the femur, another 

 less perfect stripe, and above it a longitudinal row of spots. Tibia 

 with small light spots. Upper surface of femur and tibia brown, 

 blackish varied. Inferior surfaces pale greenish- blue; top of head 

 light lirown. 



Length of head and body, 64 mm. ; length to edge of gular fold, 

 21 mm.; do. to auricular meatus, 15 mm.; width of head at rictus 

 oris, 11 mm. Length of fore limb from axilla, 21 mm.; length of 

 fore foot, 10 mm. ; length of hind leg from canthus ani, 45 mm.; do. 

 of hind foot, 24 mm. 



This species resembles very much the younger specimens of the 

 Amiva iindujata, but is a true Cnemidophorus with sagittiform 

 tongue. It differs in specific characters from both that species and 

 the A. quadrillneaia, in the possession of three rows of brachial scuta, 

 instead of one. In coloration it differs from the young striped stages 

 of those species in having three light stripes on each side instead of 

 two. The longitudinal division of the interparietal plate is a marked 

 peculiarity, but may be abnormal. The two plates together, how- 

 ever, are larger in dimensions than a single interpainetal. Among 

 C'nemidophori it is nearest to the C. lemniscatus in appearance, but 

 it differs in almost all points of squamation of the head and throat.
