ZOOLOGY— BATE AC HIANS AND EEPTILES. 



This species is about the size of the S. comobrinus, which it also resem- 

 bles in color ; but it is quite peculiar in having only three series of supra- 

 orbital scales, or only two posteriorly, from the failure of the outer row.

 Plate XXIV, Fig. 2. 



Cephalic plates smooth, the frontal transversely divided, and the 

 supraorbitals in four rows ; the latter consist of one series of transverse 

 scuta, separated from the frontal by a complete row of small scales ; a row 

 of similar small scales bounds the sharp supraoculars within, and incloses with 

 the large scuta three or two scales of intermediate size ; interparietal broad 

 as long ; parietal small, subtriangular ; scales of back, sides, and tail sub- 

 equal, strongly keeled, and mucronate ; the first named in forty-one rows 

 from head to base of tail in foiu- specimens; abdominal scales smaller, 

 notched. When the hind limb is extended, the longest toe reaches to the 

 orbit. Femoral pores fourteen; five free scuta in front of tympanum. Total 

 length, m .200 ; length to vent, m .085. 



Color bright-green, crossed above by dark blotches, interrupted on the 

 middle line, each half convex backward ; blue of sides well separated below ; 

 the entire middle portion of the throat blackish-blue. 



This species bears much relation in special points to the S. consobrinus, 

 B. & Gr., as in the number of supraorbital and dorsal scales. The outer 

 two supraorbital series are not of equal size, the inner being larger, as in S. 

 ornatus, B. & G. The coloration is quite characteristic, and the size exceeds 

 that of any of the 8. consobrinus.
