588 9. SCINCIDM 



Parietals in contact posteriorly. Supralabials seven, last 

 largest. Two azygous postmentals. Limbs overlap when 

 pressed against body. Twenty-four longitudinal rows of 

 scales, dorsals larger than laterals and ventrals. A median 

 series of transversely enlarged subcaudals, on each side of 

 which the other caudals become gradually smaller dorsally. 

 The ground color above and on the sides is dark olive. 

 There are two bluish gray lines on each side. The upper of 

 these lines originates on the internasal plate, crosses the 

 anterior loreal, prefrontal, supraocular, and parietal plate, 

 and runs along the dorsal scales (second and third rows 

 from the median line) to the tail. The lower traverses the 

 labial plates, crosses the ear-opening and runs along the side 

 of the neck and body to the hind limb, forming the lower 

 boundary of the olive ground color. The lower labials, 

 chin, throat, chest, preanal region, the lower surfaces of the 

 limbs, and the proximal half of the tail, are dull pinkish 

 buff. The belly and a faint bar across the throat, are bluish 

 gray. The tail is salmon or bright flesh color, marked, 

 except on its terminal fourth, with three narrow poorly de- 

 fined lines of slaty heliotrope, in continuation of the olive 

 ground color of the back.

Distribution. — This lizard, which is closely related to 

 Plestiodon skiltonianus, is known only from two specimens 

 secured at San Francisquito, Sierra Laguna, Lower Cali- 

 fornia. 



Remarks. — It is possible that Plestiodon lagunensis is 

 based upon mere individual variation in specimens of P.
