ZOOLOGY BATEACHIANS AND EEPTILES. 



This species is about the size of the 8. consobrinus, 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. 



SCELOPOEUS PMAEAGDLNUS, Cope, sp. nov. 

 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 four 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, CT.200 ; length to vent, O 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. & G., 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 8. 

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

 that of anv of the S. consdbrinus.
